Embodiment Construction

[0019] Describe the present invention below in conjunction with specific embodiment:

[0020] Refer to attached figure 1 , A multifunctional gear transmission test bench in this embodiment includes a motor 1, an NJ-type torque speed sensor 3, a gear transmission system 5 and a magnetic powder brake 7, all of which are installed on a test bench 8. The motor transmits power to the NJ type torque speed sensor through the first elastic sleeve pin coupling 2, and the NJ type torque speed sensor measures the rotational torque, speed and power output by the motor. The output shaft of the NJ type torque speed sensor is connected with the input shaft of the gear transmission system through the second elastic sleeve pin coupling 4 . The output shaft of the gear transmission system is connected with the magnetic powder brake through the third elastic sleeve pin coupling 6 . The magnetic powder brake provides load for the test device, and the test conditions under different load states ...

Abstract

The invention provides a multifunctional gear transmission testboard, which includes an electric motor, a torque revolving speed sensor, a gearbox and a brake, wherein the gearbox includes one input shaft, two intermediate shafts and one output shaft which are all mounted in parallel. According to the invention, shafts at different positions and corresponding gears in the gearbox can be dismounted on a base of a testing platform, so as to form a stand-alone power two-branch gear transmission wheel train structure, a two-stage expanded gear transmission wheel train structure, a single-stage independent torsion type gear transmission wheel train structure and a single-stage gear transmission wheel train structure; gears with web boards of different thicknesses and shafts of different diameters can be replaced to vary the rigidity of web boards of the gears and the torsional rigidity of the shafts, so that the dynamic performances of the power two-branch transmission system under different rigidity of the web boards of the gears and the torsional rigidity of the shafts can be studied, and testing support for rigidity of the web boards and the shafts can be provided.

Description

technical field [0001] The invention relates to the technical field of gear mechanical transmission tests, in particular to a multifunctional gear transmission test bench. Background technique [0002] With the development of industry and the increase of engine power, the requirements for the torque transmission capacity of gear transmission are also increased. Under the premise of the same transmission size and quality, the ways to improve the torque transmission capacity are: first, tooth surface hardening treatment (and gear modification and other measures); second, multi-branch power split transmission. The former often requires additional equipment, such as large heat treatment equipment and gear grinding machines. Since the weak link of gear transmission strength is the gear teeth, multi-branch power splitting can reduce the load on the gear teeth, thereby reducing the size and mass of the gear transmission. [0003] The basic principle of power splitting technology ...
