Description

Technical Field

[0001] This utility model belongs to the field of testing technology for lubricating materials for speed reducers, specifically relating to a device for testing the wear resistance of lubricating materials for planetary speed reducers of floor scrubbers. Background Technology

[0002] A planetary reducer is a power transmission mechanism that uses gears to reduce the speed of a motor to the desired speed while obtaining a larger torque. Because planetary reducers can increase torque, the forces between the gears inside are relatively large. To reduce wear, lubricating materials are usually added inside, which not only lubricate but also dissipate heat, extending service life. Current testing of lubricating materials used in planetary reducers for floor scrubbers, particularly measuring noise, temperature rise, vibration, and torque caused by different lubricating materials under normal operating conditions at a maximum speed of 3000 rpm, mainly relies on physicochemical parameter tests such as cone penetration, dropping point, viscosity, and pumpability, as well as performance tests of four-ball, Timken, and FZG gears, and stability tests such as colloid, oxidation, and mechanical tests. However, these tests are relatively standard and have limited or no relevance to simulating the actual operating conditions of planetary reducers, failing to simulate and quantify the test data.

The test bracket 6 is vertically positioned on the right side of the coupling A2, and its upper mounting hole connects to the planetary reducer 8 at the other end. The input end of the planetary reducer 8 is connected to the output end of the stepper motor 10, and the vibration sensor 9 is positioned on the upper part of the stepper motor 10. The laser sensor 7 is positioned on the outside of the test bracket 6, with its test head parallel to the planetary reducer 8. The magnetic powder brake 5 is positioned on the left side of the top surface of the base plate 1, and symmetrical supports 11 are equidistantly arranged on both sides for its erection. The shaft end of the coupling B4 passes through the mounting hole on the upper part of the support 11 and is interconnected with the magnetic powder brake 5. The magnetic powder brake 5 is used for testing here. The magnetic powder brake 5 is based on the electromagnetic principle and uses magnetic powder to transmit torque. It can transmit a certain torque without being related to slip. It has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration and energy saving. At the same time, it is calibrated by the dynamic torque sensor 2. By adjusting the torque linear range of the magnetic powder brake 5, the voltage corresponds to the torque. It can be finely adjusted and quantified to make the load reach a constant test. It is used to test the wear resistance of the reducer lubricating material under the corresponding ideal working conditions.

The outer end of the reciprocating shaft 18 is interconnected with the load shaft 15, and a bearing 20 is provided at the junction of the reciprocating shaft 18 and the swing disk 17; a weight 21 is sleeved on the upper part of the load shaft 15; a linear bearing 22 is also provided at the junction of the load shaft 15 and the linear seat 14; the load shaft 15 and the weight 21 move in a reciprocating motion, with the torque increasing when moving upward and decreasing when moving downward, and changing back and forth; the torque can be changed by increasing or decreasing the number of weights, which can be used to test the wear resistance of the reducer lubricating material under the condition of periodic load change.

[0019] In practical use, this invention involves filling the planetary reducer 8 with a fixed amount of lubricating material, mounting the assembled planetary reducer 8 and stepper motor 10 onto the test bracket 6, tightening the coupling, installing the vibration sensor 9, adjusting the target position of the laser sensor 7, setting parameters such as speed, duration, and load value, starting the test, and completing the test according to the settings. Data such as starting torque, operating torque, noise, temperature rise, and vibration are obtained through an embedded algorithm. This device uses a controllable load or periodic load to replace the original installed load, ensuring stable and controllable load with precise load quantity. Different load quantities can be added for testing as needed, greatly improving test repeatability and accuracy. This integrated testing device combines a fixed torque load, reciprocating simulated load, closed-loop speed control, precision torque sensor, data acquisition, and data algorithm, enabling standardized measurement of the wear resistance of lubricating materials used in planetary reducers for floor scrubbers, solving the problem that traditional methods cannot simulate and quantify test data.
