Description

A self-loading torque device

technical field

The invention relates to an automatic loading device, in particular to an automatic loading torque device for a polymer composite material gear contact fatigue friction and wear testing machine.

Background technique

With the development of material science and the improvement of the lightweight requirements of industrial products, polymer composite materials are more and more widely used in gear production. In order to better study the friction and wear mechanism of polymer composite gears and the impact of polymer composite The material gear is used for life prediction, and the torque loading device of the polymer composite gear testing machine is studied. The traditional loading device will jump when the testing machine is running at high speed, which will cause large errors and inaccurate test data. Moreover, the traditional loading device cannot realize automatic loading, and the test efficiency is low.

Contents of the invention

The purpose of the present invention is to design an automatic loading torque device, which realizes the automatic loading of the torque of the test gear through a lead screw motor, a lead screw, a weight, a loading clutch and a pivot box, and is easy to operate, safe and efficient.

In order to achieve the above object, the present invention adopts the following technical solutions: an automatic loading torque device, the structure of which includes a transmission system and a loading system. The transmission system includes a motor. One end of the motor is connected to the pulley. The power output by the motor is transmitted to the test gearbox through the pulley. The test gearbox is connected to the transmission shaft. The power output by the test gearbox is transmitted to the test gear through the transmission shaft. The loading system includes a loading clutch, a pivot box, and one end of the pivot box is connected to a lead screw motor, which is connected to the lead screw through an elastic coupling, and the upper end of the lead screw is connected to a weight plate, and a weight is placed in the weight plate code.

The weight plate is connected with the lead screw through the lead screw nut, so that the free movement of the weight plate can be realized.

The driving shaft is connected with a loading clutch, and the loading clutch, the weight and the pivot box jointly complete the torque loading to the test gear.

The support frame for fixing the lead screw motor is fixedly connected with one end of the pivot box through set screws.

Detailed ways

In order to better understand the technical solution of the present invention, the automatic loading torque device will be further described below in conjunction with the accompanying drawings.

An automatic loading torque device, the structure of the automatic loading torque device includes a motor (1), one end of the motor (1) is connected to a small pulley (2), and the small pulley (2) is connected to a large pulley ( 4), one end of the large pulley (4) is connected to the driving shaft (8), the driving shaft (8) is connected to the accompanying gearbox (5), and the accompanying gearbox (5) is connected to the driven shaft (9). The loading clutch (6) is connected to the shaft (8), the universal joint (7), the pivot box (11) and the test gear (12) are connected to the driving shaft (8) and the driven shaft (9) , one side of the pivot box (11) is connected with the displacement sensor (10), and the other side of the pivot box (11) is connected with the pivot box support hinge (13) and the lead screw motor (14), and the lead screw motor (14) passes through The elastic coupling (15) is connected to the lead screw (17), the two ends of the lead screw (17) are connected to the bearings (16), the upper end of the lead screw (17) is connected to the weight plate (18), and the weight plate (18) is placed There are weights (19). During the test, after the test gear is installed, disconnect the loading clutch (6), turn the pivot box (11) to adjust the system to a certain angle, then close the loading clutch (6), and put the weight ( 19), start the lead screw motor (14), make the weight plate (18) move freely, the pivot box (11) will rotate around the pivot box supporting hinge (13), until the driving shaft (8) and the driven shaft (8) When the shafts (9) are parallel to each other, stop the lead screw motor (14). At this time, the torque generated by the weight (19) is loaded onto the test gear through the pivot box (11), so as to realize the automatic loading of the torque of the test gear.
