Novel dynamometer

Abstract

The invention discloses a novel dynamometer. The novel dynamometer comprises a front vertical plate, the rear side of which is provided with a rear vertical plate matched with the front vertical plate. The front vertical plate and the rear vertical plate are localized by positioning pins, and are connected together. An opening is formed between the front vertical plate and the rear vertical plate, and a brake is erected on the opening. The brake is erected between the front vertical plate and the rear vertical plate by a rotating shaft. The brake comprises a rotor disposed on the outer part of the rotating shaft in a sleeved way, and a stator matched with the rotor is disposed on the outer part of the rotor in a sleeved way. The front end of the rotor is fixedly provided with a rotor end cover. The rotor end cover is connected with a rotor cup, and the rotor cup is disposed on the outer part of the rotor. One end of the rotating shaft is extended out of the front vertical plate in a penetrating way, and the other end is disposed in the rear vertical plate. The end of the rotating shaft disposed in the rear vertical plate is connected with a code disc. The novel dynamometer is advantageous in that heat dissipation performance is better, and operation is more stable; during the operation of the dynamometer, hot air is led to the outside the first time, and a rapid cooling effect is achieved, and therefore the stable and normal operation of the dynamometer is guaranteed.

Description

technical field [0001] The invention relates to a new type of dynamometer. Background technique [0002] The dynamometer can be used to test the torque, speed, power, etc. of the engine, and can also be used as a loading device for the gearbox, reducer, and gearbox to test them. Traditional dynamometers use sensors to sense the torque of the engine, The speed, power, etc. are digitized, and the front and rear supports of the dynamometer are mostly split structures. The machining of the bearing holes on the front and rear support structures is prone to errors, resulting in errors in assembly accuracy and affecting measurement accuracy. [0003] During the operation of the dynamometer, high temperature will be generated inside the dynamometer. Most dynamometers will set cooling pipelines in the stator and use cooling water to cool down. However, this way of cooling has requirements on the structure and does not It is not suitable for all types of dynamometers, and the cooling...

[0003] During the operation of the dynamometer, high temperature will be generated inside the dynamometer. Most dynamometers will set cooling pipelines in the stator and use cooling water to cool down. However, this way of cooling has requirements on the structure and does not It is not suitable for all types of dynamometers, and the cooling is carried out through the cooling pipeline. It is necessary to set the water inlet pipe and the water outlet pipe on the front vertical plate to connect the cooling pipeline. When testing the torque, the brake of the dynamometer will appear With a certain swing, the water inlet pipe and the water outlet pipe will form a corresponding pulling force, which will pull the swinging brake, thus affecting the measurement accuracy
