What are the types of output shafts for YTC shaft mounted gear reducers

The output shaft of YTC shaft mounted gear reducer mainly adopts a single end output shaft structure, usually a cylindrical solid shaft with a flat keyway or spline interface, used to directly connect load equipment such as rollers, sprockets or pulleys. This design eliminates the need for intermediate couplings, achieving a compact and efficient transmission layout.

1、 Main types and characteristics of YTC gearbox output shaft

1. Standard cylindrical solid shaft (with flat keyway)

The most common form of output shaft has a standard sized keyway machined on the shaft end (such as 14 × 8 × 32, 16 × 10 × 40, etc.), which is matched with keys and fastening nuts to transmit power to external components.

The advantages are simple structure, low cost, and strong universality, suitable for most conveying, packaging, and light industry machinery scenarios.

2. Spline output shaft

The use of involute spline shafts under high torque or frequent start stop conditions can improve the connection strength and alignment accuracy between the shaft and the load hub.

The spline has a larger meshing area, stronger load-bearing capacity, and better impact resistance than the flat key structure. It is commonly used in heavy-duty conveyor lines or metallurgical equipment.

3. Hollow shaft (a few customized models)

A few YTC series variant products can be equipped with a hollow shaft structure, allowing the driven shaft to pass through the output end of the gearbox, achieving a more compact spatial layout.

Commonly seen in special equipment with extremely limited space or requiring a central axis, but not in the mainstream configuration of YTC.

2、 Support and installation method of output shaft

1. Cantilever support structure: The output shaft is supported on one side by the internal bearing of the reducer, forming a cantilever beam structure that directly connects to the external load. This design simplifies installation, but requires that the radial and axial forces of the load be within the allowable range to avoid early bearing wear caused by overload.

2. Axial positioning and sealing: The output end is equipped with a skeleton oil seal and a slinger ring to prevent lubricating oil leakage; Some models have positioning steps at the shoulder of the shaft to ensure accurate axial positioning of the connecting components.
