Description

Technical Field

[0001] This utility model relates to a compaction test platform, specifically to a transmission mechanism applied to a large compaction test platform. Background Technology

[0002] With the rapid development of the national new energy industry, especially the increasing demand for new energy vehicle-related components, the car frame and transmission box need to be designed to be lightweight. In order to ensure the reliability of structural components, rolling tests are required to test whether the deformation of structural components under different rolling pressures can meet the requirements.

[0003] Existing pressure testing equipment has low rolling pressure and inconvenient rolling speed adjustment, which cannot meet the pressure testing requirements of structural components and makes it inconvenient to adjust the test cycle. Summary of the Invention

[0004] The purpose of this utility model is to provide a transmission mechanism for a large rolling test platform, which can adjust the speed of the rolling roller according to actual use requirements, and can brake quickly, thereby improving transmission reliability and saving equipment operating costs.

[0005] The technical solution of this utility model is as follows: The transmission mechanism applied to a large compaction test platform consists of a transmission assembly mounted on a support assembly. The support assembly includes: a first support base, a second support base, a main support, a motor support, a first base, a main support bracket, and a second base. The transmission assembly includes: a transmission shaft, a compaction roller, a diaphragm coupling, a planetary reducer, a drum gear coupling, and a speed-regulating motor. The main support bracket is welded to the first and second bases, and the main support is bolted to the main support bracket. The motor support is bolted to the main support, and the first and second support bases are bolted side-by-side to the first and second bases. The speed-regulating motor is mounted on the motor support, and the planetary reducer is mounted on the main support. The speed-regulating motor is linked to the planetary reducer via the drum gear coupling. The transmission shaft is mounted on the first and second support bases, and the planetary reducer is linked to the transmission shaft via the diaphragm coupling. The compaction roller is linked to the transmission shaft via a spline.

[0006] A further design incorporates a brake on the speed-regulating motor.

[0007] Further design features a split upper and lower support base, which is fixed with bolts.

[0008] The advantages of this utility model are: 1. A speed-regulating motor with a brake is used, which provides multiple speeds for the transmission system and achieves rapid braking in a more economical way, for stopping the rolling system and preventing the rolling rollers from reversing.

[0009] 2. The speed-regulating motor and the planetary reducer are connected by a drum-shaped gear, which can not only compensate for the alignment error between the motor and the reducer, but also reduce the impact of rolling impact on the motor.

[0010] 3. The planetary reducer and the drive shaft adopt a diaphragm coupling to reduce the impact of crushing and impact on the reducer; if the overload is severe, the diaphragm coupling will be damaged first, avoiding the impact on the reducer and motor.

[0011] 4. The drive shaft and the rolling roller are connected by a spline, which facilitates disassembly and assembly.

[0012] 5. This utility model has a simple structure and flexible combination, providing high rolling pressure and multi-cycle working range for rolling equipment, improving equipment reliability and facilitating maintenance. Attached Figure Description
