Abstract

The invention relates to the field of tensioning devices, and discloses an automatic tensioning device for an electric generator. The automatic tensioning device comprises an engine, the electric generator, a driving wheel, a driven wheel and a belt. The engine is provided with a first side wall and a regulating device. A rotating base is provided with a second side wall. The first side wall and the second side wall form a V-shaped groove. The regulating device comprises a piston cylinder and a piston. The piston is connected into the piston cylinder in a sliding mode. The piston is conical and abuts against the first side wall and the second side wall. A fixing ring coaxial with the electric generator is arranged on the periphery of the electric generator. A plurality of inflators are fixed to the inner wall of the fixing ring. Air plugs are connected into the corresponding inflators in a sliding mode, and compressed springs are arranged between the air plugs and the outer wall of the electric generator. All the inflators communicate with the piston cylinder through an air pipe. The automatic tensioning device for the electric generator is provided, and accordingly the electric generator belt can be tensioned automatically.

Description

technical field [0001] The invention relates to the field of tensioning devices. Background technique [0002] The alternator of the automobile is installed on the engine and is connected with the driving wheel of the engine through a belt. The pre-tightening force of the belt has a great influence on the generating efficiency, life and shaft pressure of the alternator. Insufficient pre-tightening force will result in low load transmission capacity and low power generation efficiency, and will cause the driven wheel on the generator to heat up rapidly, resulting in belt wear; excessive pre-tightening force will cause the generator bearings to heat up and wear. Therefore, ensuring the proper preload of the generator is an important factor to ensure the normal operation of the belt drive. [0003] However, during the use of the generator, the pre-tightening force of the belt will gradually decrease due to wear or aging of the belt; at the same time, the bearings in the genera...
