Metal Helical Power Transmission Gears

The performance of gear transmission systems centers on coordinated control of tooth profile accuracy, surface hardness, and meshing characteristics.

Sprocket gears are essential mechanical components used to transfer rotary motion and mechanical power through chain-driven systems. Unlike conventional gears that directly mesh with one another, sprocket gears engage with the links of a chain, creating a positive and dependable transmission connection. They are widely used in conveyors, agricultural machinery, industrial equipment, packaging systems, motorcycles, bicycles, and many other mechanical applications.

Internal gears are precision transmission components in which the teeth are formed on the inside surface of a ring-shaped gear. When paired with an external gear, planetary gear, or pinion, they can deliver compact power transmission, high torque capacity, smooth engagement, and efficient use of installation space. However, choosing the wrong tooth profile, material, manufacturing tolerance, lubrication method, or mating gear can lead to noise, accelerated wear, backlash, and premature failure.

Many manufacturers of office equipment, medical devices and small robots are looking for lightweight, low-noise transmission parts to replace expensive metal bevel gears. Conventional metal bevel gears add extra weight to finished products, require regular lubrication and bring higher production costs, which cannot match the lightweight and low-maintenance design direction of consumer electronics and portable medical machinery. With over 30 years of gear manufacturing experience since 1988, Feida Machinery launches high-precision plastic straight bevel gears manufactured by advanced CNC gear processing equipment, solving multiple pain points of light-load transmission through optimized plastic material formulas and conical straight-tooth structural design.

Metal Straight Bevel Gears are compact mechanical components designed to transmit rotary motion and torque between intersecting shafts, commonly where a change in transmission direction is required. Their straight tooth geometry gives them a relatively simple construction and makes them suitable for many industrial mechanisms where dependable power transfer, compact installation, controllable manufacturing cost, and straightforward maintenance are important.
