Embodiment Construction

[0030] The rotational torque, radial force and axial force comprehensive loading test method of a kind of transmission system of the present embodiment, such as Figure 1~Figure 4 shown, including the following steps:

[0031] a. Install a pair of transmission system I1 and transmission system II1' back-to-back, between the transmission system I1 and the back-to-back connection flange I2, the conical surface 11 of the hub of the transmission system I1 matches the conical surface 21 of the back-to-back connection flange I2, and The press-fit bolt I12 screwed into the hub 17 of the transmission system I1 presses the pressure block I13 used to limit its axial displacement and is fixedly connected; between the transmission system II1' and the back-to-back connecting flange II2' passes through the hub of the transmission system II1' The conical surface 11' matches the conical surface 21' of the back-to-back connection flange II2', and presses the pressure block II13 for limiting it...

Abstract

The invention provides a comprehensive loading test method and device for the rotational torque, radial force and axial force of the transmission system, which provides the rotation speed and torque by driving and loading the motor to complete the rotational torque loading of the transmission system; using the radial force loading device The oil cylinder is equipped with the radial force loading device roller supported by the radial direction to complete the radial force loading of the transmission system; the axial force loading device oil cylinder is used together with the slip ring of the axial force loading device to complete the axial force loading of the transmission system; The control system precisely controls the torque and speed of the motor and the thrust of the oil cylinder of the radial force loading device and the axial force loading device, realizing the comprehensive loading of the rotational torque, radial force and axial force of the transmission system.

Description

technical field [0001] The invention belongs to the technical field of transmission system testing, and in particular relates to a test method and device for comprehensive loading of rotational torque, radial force and axial force during a gear transmission system loading test. Background technique [0002] The transmission system, especially the gear transmission system, such as wheel speed reducer, wind power gearbox, etc., is generally compact in structure due to the limited installation space; and its loading conditions are extremely complicated due to the harsh operating environment. Therefore, the performance requirements of the transmission system are extremely high, and high requirements are also put forward for the test and inspection. [0003] In order to verify the performance of the product, in the prior art in the transmission system field, the no-load running-in or rotational torque loading test is usually used to replace the test of installing the transmission...
