Shaanxi TGL (NL) nylon internal gear coupling

TGL (NL) nylon internal gear coupling is a national standard model. Another nylon internal gear coupling produced by our factory is NL nylon internal gear drum gear coupling.

●Nylon inner ring gear coupling: The inner ring gear adopts MC nylon material, and the outer gear shaft sleeve adopts No. 45 forged steel. It has small size, light weight, low moment of inertia, low noise, easy assembly and disassembly, no lubrication, etc. Advantages, can be applied to small and medium torque working conditions, such as fans, water pumps, lubrication pumps, textile machinery, etc.

●TGL (NL) nylon internal gear coupling has the following three structural types:

A---type basic type: B---type inner retaining ring type: C---type outer retaining ring type

Drum-shaped gear coupling parts structure diagram As a transmission device, the drum-shaped gear coupling has evolved from the development of ordinary straight-tooth couplings. Drum-shaped gear couplings have various standards and standards in many industries. The series of products consist of two drum-shaped outer gear sleeves and a pair of straight-tooth inner gear rings.The torque is transmitted by the meshing of the inner and outer teeth, and the axis of the inner ring gear of the straight teeth of the drum-shaped outer gear sleeve is oscillated (called angular displacement) to compensate for the relative deviation of the two transmission axes.The greater the bulge in the tooth length direction, the greater the angular displacement, up to 6°. Generally, 1°～1.5° is recommended for use, while the old gear coupling only allows 0.5°; from the point of view of bending strength and load-bearing capacity, Under the same working conditions, the transmission torque of the drum gear coupling can be increased by 15-20%.The bulge in the tooth length direction makes the tooth pair contact better. Therefore, the drum gear coupling has the advantages of large transmission capacity, large angular displacement, stable transmission, and long life.

What is the difference between TGL (NL) nylon internal gear coupling and NL nylon coupling?

TGL (NL) type nylon internal gear coupling is similar in structure to the NL type nylon coupling that is often said on the market, but the performance and size are not right. When purchasing, the collective name of NL1 and TGL1 cannot be reduced.

Structural features of TGL (NL) nylon internal gear coupling:

1. It has high cushioning and vibration reduction performance, and has a large range of compensation capabilities for axial, angular, and radial displacement deviations.

2. Due to the cooperation of engineering plastics and metal parts, it has good self-lubricating performance and is an ideal approximate universal elastic coupling.

3. The shell mold forming simplifies the processing technology and has low cost.The operating environment temperature is -20ºC+80ºC.

4. Assembly and maintenance are particularly simple.It is widely used in various hydraulic pumps, lubricating pumps, pneumatic pumps, compressors, textile machines and other machinery.
