Torque loader and closed power flow type gearbox testing device

Abstract

The invention provides a moment loader and a closed power flow type gearbox testing device, wherein the moment loader comprises a first rotating disc which is used for connecting an external to-be-tested first gearbox, a second rotating disc and a worm; the second rotating disc is used for connecting an external to-be-tested second gearbox; gear teeth are arranged in the circumferential direction of the second rotating disc, and the second rotating disc is located on one side of the first rotating disc; and the worm is rotationally mounted on the first rotating disc and meshed with the gear teeth on the second rotating disc, the worm rotates to drive the second rotating disc to rotate, and the worm and the second rotating disc can be self-locked, wherein the axis of the worm and the axis of the second rotating disc are arranged at an angle. Through meshing self-locking of the worm and the gear teeth, the torque loader can be automatically locked after loading torque, other auxiliary devices are not needed, the structure of the torque loader is effectively simplified, and the cost of the torque loader is reduced; the moment loading process is safer; the torque loading direction adjustment operation is simple and convenient; and the whole torque loading and adjusting process is simple and quick to operate.

Description

technical field [0001] The invention relates to the field of mechanical experiment equipment, in particular to a moment loader and a closed power flow type gearbox testing device. Background technique [0002] Loading test is a very important method for performance verification in the design and processing of gears and gearboxes. The moment loader device is one of the key devices in the closed power flow gearbox test device. Compared with the open power flow gearbox test device, the closed power flow gearbox test device has been paid more and more attention to and adopted because of its advantages of low power consumption, high efficiency and energy saving, and low experimental cost. [0003] The common moment loader devices currently on the market are polarized. For example, mechanical torque loaders with relatively simple structures such as "thread type" or "pawl external type", but their torque adjustment range is small, and the torque adjustment is segmented, which can...

AI Technical Summary

Problems solved by technology

For example, mechanical torque loaders with relatively simple structures such as "thread type" or "pawl external type", but their torque adjustment range is small, and the torque adjustment is segmented, which cannot be accurately adjusted to any torque value, and the operation is complicated; For example, "planetary gear transmission mechanism and servo motor and control system", "hydraulic loading and servo control system" and other torque loading devices with precise control and precise torque adjustment, but their structures are too complicated, the price is extremely expensive, and the operation is complicated and inconvenient use

Therefore, the closed power flow gearbox test bench is limited to be widely used

[0004] In addition, at present, some mechanical moment loaders with simple structures can only load torque in one direction, which are less suitable for working conditions and have a smaller application range; of course, there are also mechanical moment loaders that can load forward and reverse torques. However, when adjusting the loading direction, it is necessary to add other auxiliary structures to complete the adjustment of the moment loading direction, the adjustment operation is complicated, and the structural cost is high
