specialized in manufacture cast nylon polyamide palstic gear wheels 
Nylon is a kind of engineering plastics used in comprehensive industries, has been applied almost every industrial field.The caprolactam monomer is first melted, and added catalyst, then poured it inside moulds at atmosphere pressure so as to shape in different castings, such as: rod, plate, tube.
 

Since the end of 1980’s, HangZhou Engineering Plastics Industireis Company has devoting herself on developing the technology of Nylon modification, greatly extended the applications in different industries. Basing on the Nylon, reinforced with variety of additives during the reaction, such as lubricant, molybdenum disulfide, graphite glass fiber, carbon fiber etc, to improve the properties, higher performance of wear-resistance, corrosion-resistance, self-lubrication, vibration-absorption, noise-absorption. At the same time, as the technics and structure of the moulds is quite simple, so that it can be manufactured in lower cost, becomes the ideal substitutes of bronze, stainless steel, Babbitt alloy,PTFE and so on.
 
Oil Nylon (green)
 
Oil Nylon(green)is the new engineering plastics that developed by HangZhou Engineering Plastics Industireis Company in the later 1980’s by importing the advanced technology from Nylacast Co., Ltd, UK, was the first authentic lubricating nylon that builds the liquid lubricant system during the processing stage, which makes its coefficient of friction is 50% lower than the general PA6 or PA66, the wear-resistance is 10 times than the general ones. Oil Nylon is specially developed for the parts of non-self-lubrication, heavy-loading and low-speed-running, which obviously resulted in a substantial increase in bearing life-5 times that of general PA6 and 25 times that of phosphor bronze! The lubricant contained within the material will not drain, adsorb or dry out and never needs replenishment. The uniform distribution of the lubricant throughout the product guarantees the constant performance of the parts over the whole service life and improvements in rate of wear, sliding frictional properties, abrasion resistance and stick slip performance, which are just a few of the benefits offered by this material. Oil Nylon has been successful in considerable enlarging the application of nylon in many industries and specifically for some un-lubricated running parts.

What is the purpose of using spur gears in machinery?

In machinery, spur gears serve several important purposes due to their unique characteristics and capabilities. Here’s a detailed explanation of the purpose of using spur gears in machinery:

  1. Power Transmission: Spur gears are primarily used for power transmission in machinery. They transfer rotational motion and torque from one shaft to another, allowing machinery to perform various tasks. By meshing the teeth of two or more spur gears together, power can be transmitted efficiently and reliably throughout the machinery.
  2. Speed Reduction or Increase: Spur gears enable speed reduction or increase in machinery. By combining gears with different numbers of teeth, the rotational speed can be adjusted to match the desired output speed. For example, using a larger gear driving a smaller gear can increase the speed output while reducing the torque, while the opposite arrangement can decrease the speed while increasing the torque.
  3. Torque Amplification: Spur gears can amplify torque in machinery. By using gears with different numbers of teeth, the torque can be adjusted to match the required output. For example, using a smaller gear driving a larger gear can increase the torque output while reducing the speed, while the opposite arrangement can decrease the torque while increasing the speed.
  4. Directional Control: Spur gears provide directional control in machinery. By meshing gears with opposite orientations, the rotational direction of the driven shaft can be reversed or changed. This directional control is crucial for machinery that requires bi-directional motion or needs to change the direction of operation.
  5. Mechanical Advantage: Spur gears offer a mechanical advantage in machinery. By utilizing gear ratios, spur gears can multiply or divide the force exerted on the input shaft. This mechanical advantage allows machinery to generate higher forces or achieve precise movements with reduced effort.
  6. Precision Positioning: Spur gears facilitate precise positioning in machinery. The accurate tooth engagement of spur gears ensures precise control over rotational motion, making them suitable for applications that require precise positioning or synchronization of components. Machinery such as CNC machines, robotics, and automation systems often rely on spur gears for accurate movement and positioning.
  7. Compact Design: Spur gears have a compact design, making them suitable for machinery with space constraints. They can be arranged in-line, parallel, or at right angles, allowing for efficient power transmission in tight spaces. Their compactness enables machinery to be designed with smaller footprints and optimized layouts.
  8. Reliability and Durability: Spur gears are known for their reliability and durability in machinery. The direct tooth engagement and uniform load distribution result in efficient power transmission with reduced wear and stress concentration. When properly lubricated and maintained, spur gears can withstand heavy loads and operate reliably over extended periods.
  9. Cost-Effectiveness: Spur gears are often cost-effective in machinery applications. Their simple design and ease of manufacturing contribute to lower production costs. Additionally, their high efficiency helps reduce energy consumption, resulting in potential long-term cost savings. The availability of spur gears in various sizes and materials further enhances their cost-effectiveness.

By utilizing spur gears in machinery, engineers and designers can achieve efficient power transmission, speed and torque control, directional versatility, mechanical advantage, precise positioning, compact design, reliability, durability, and cost-effectiveness. These advantages make spur gears a popular choice in a wide range of machinery applications across industries.

What is a spur gear and how does it work?

A spur gear is a type of cylindrical gear with straight teeth that are parallel to the gear axis. It is one of the most common and simplest types of gears used in various mechanical systems. Spur gears work by meshing together to transmit rotational motion and torque between two parallel shafts. Here’s a detailed explanation of spur gears and how they work:

A spur gear consists of two or more gears with cylindrical shapes and an equal number of teeth. These gears are mounted on parallel shafts, and their teeth mesh together to transfer rotational motion from one gear to another. The gear with power input is called the “drive gear” or “driver,” while the gear receiving the power output is called the “driven gear” or “follower.”

The key characteristics and components of spur gears include:

  • Teeth: Spur gears have straight teeth that are cut parallel to the shaft axis. The teeth are evenly spaced around the circumference of the gear. The number of teeth determines the gear ratio and affects the speed and torque transmission between the gears.
  • Pitch Diameter: The pitch diameter is the theoretical diameter of the gear at the point where the teeth mesh. It is determined by the number of teeth and the module or diametral pitch of the gear.
  • Module or Diametral Pitch: The module is a parameter used in metric gear systems, while the diametral pitch is used in imperial gear systems. They define the tooth size and spacing of the gear. The module is the ratio of the pitch diameter to the number of teeth, while the diametral pitch is the number of teeth per inch of pitch diameter.
  • Pressure Angle: The pressure angle is the angle between the line tangent to the tooth profile at the pitch point and a line perpendicular to the gear axis. Common pressure angles for spur gears are 20 degrees and 14.5 degrees.
  • Meshing: Spur gears mesh by engaging their teeth, creating a point or line contact between the contacting surfaces. The teeth transfer rotational motion and torque from the drive gear to the driven gear.
  • Gear Ratio: The gear ratio is determined by the number of teeth on the drive gear and the driven gear. It defines the relationship between the input speed and the output speed. The gear ratio can be calculated by dividing the number of teeth on the driven gear by the number of teeth on the drive gear.
  • Operation: As the drive gear rotates, its teeth come into contact with the teeth of the driven gear. The contact between the teeth transfers rotational motion and torque from the drive gear to the driven gear. The meshing teeth maintain a constant speed ratio, allowing for the transmission of power between the shafts. The direction of rotation can be changed by meshing gears with an odd or even number of teeth.

Spur gears offer several advantages, including simplicity, ease of manufacture, efficiency, and reliability. They are commonly used in a wide range of applications, including machinery, automotive systems, appliances, power tools, and more.

In conclusion, spur gears are cylindrical gears with straight teeth that mesh together to transfer rotational motion and torque between parallel shafts. Their simple and efficient design makes them a popular choice for various mechanical systems.
