Electric synchronous loader

Abstract

The invention provides an electric synchronous loader which comprises a base, a speed reducer, a loading motor, a brake, a braking frame assembly and a second left end cover, wherein the speed reducer comprises a first-stage casing, a fixed inner tooth ring, a second-stage casing and an output-end supporting seat which are connected in sequence to form a rotary housing of the speed reducer; the loading motor comprises a motor housing and a rear cover which form a rotary housing of the loading motor; the brake is arranged in a tail inner cavity of the loading motor and integrally combined with the loading motor; the braking frame assembly is arranged on the second left end cover and connected with an external lead wire for introducing an external three-phase power supply. The electric synchronous loader can be used for realizing no-load starting of a test device and freely changing the size and the direction of a torque in a running process, and is infinite in loading travel angle, high in loading precision, automatic in load locking, stable in running, allowable in high-speed rotation, large in loading torque, small in external contour size, high in reliability, low in loading motor power, low in use cost and good in economy.

Description

technical field [0001] The invention relates to the field of loaders, in particular to an electric synchronous loader. Background technique [0002] In the mechanical power closed gear test device, the loader is a very important part. When used to simulate the actual working load of the tested gearbox, the performance of the loader directly affects the performance and technical and economic indicators of the mechanical power closed gear test device. Therefore, the quality of the loader determines the success or failure of the design of the mechanical power closed gear test device The essential. [0003] At present, loaders used in mechanical closure test devices are mainly divided into three categories: [0004] (1) Internal force loader: This type of loader has the advantages of simple and compact structure, good processing and assembly process, convenient maintenance, low energy consumption and low noise during operation, but loading and unloading can only be carried out...

Problems solved by technology

[0004] (1) Internal force loader: This type of loader has the advantages of simple and compact structure, good processing and assembly process, convenient maintenance, low energy consumption and low noise during operation, but loading and unloading can only be carried out when the test is stopped , and it is impossible to start the test device without load and change the magnitude and direction of the load during operation

[0005] (2) External force loader: This type of loader can be loaded by external force (mechanical force, hydraulic pressure, air pressure, etc.) during static or running, and can realize the no-load start-up of the test device, and can change the load during operation and direction, however, there are disadvantages such as limited loading stroke angle or complex connection (movable joint) of external force transmission line and too many auxiliary equipment.

[0006] (3) Moment loader: This type of loader uses meshing transmission to generate torque to load the closed system, and can be loaded and unloaded during operation. However, there are limited loading stroke angles or meshing loss and transmission noise or damage to the loading motor. Disadvantages such as high requirements and complex structure

[0007] At present, the commonly used electric synchronous loader is a torque type loader, which has low loading accuracy, poor running stability, self-loosening, too small loading torque and too large external size, allowing low-speed rotation, high production cost, and high reliability. Low-level problems need to be further improved and perfected
