Abstract
The utility model discloses a transmission system at the front end of an earthmover engine, which comprises a stand, a fan bracket, an engine, a water pump and a generator, wherein the fan bracket, the engine, the water pump and the generator are arranged on the stand; a fan bracket pulley is connected with a crankshaft pulley of the engine through a belt I; a water pump pulley, a generator pulley and the fan bracket pulley are connected through a belt II; and the stand is provided with an automatic tension pulley and an idle pulley of the belt I. According to the transmission system at the front end of the earthmover engine, the belt used for connecting the water pump pulley, the generator pulley with the fan bracket pulley can automatically tension; the problems that belt tension is uneven, the belts slip, abnormal sound is generated by the belts and the like cannot be generated when the height difference between the crankshaft center and the fan center of the engine is greater. The transmission system at the front end of the earthmover engine is suitable for earthmovers. The automatic tensioning of the belts is realized without manual regulation; the belt tension is ensured to be constant; and the slipping, the abnormal sound and the excessive tension of the belts are avoided, so that the belts are always in the best tensioning state.
Description
Technical field
The utility model relates to a kind of bulldozer motor head transmission system.
Background technique
At present loader all adopts belt to carry out power transmission with diesel engine front end transmission system, and the existing mode that belt is carried out tensioner is common expansion tightening wheel tensioner, and installing afterwards, the train fixed-site can't change.Because it is aging that belt occurs in long-term the use easily, cause belt tension uneven, skid, abnormal sound even fracture, reduced the Security and the reliability of diesel engine.And bulldozer is high with fan center's height ratio loader of diesel engine, and the requirement of belt is more increased.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of belt tension performance good bulldozer motor head transmission system.
In order to solve the problems of the technologies described above; The utility model comprises frame and rack-mounted fan bracket, motor, water pump and generator; The crank pulley of fan bracket belt pulley and motor is connected through belt one; Water pump pulley, generator pulley and fan bracket belt pulley are connected through belt two, and described frame is provided with the automatic expansion tightening wheel and the idle pulley of belt one.
Be connected with turnbuckle between said water pump and the generator; The housing of water pump is fixed on the frame, and the housing of generator is rotationally connected through bearing pin and frame, and an end of turnbuckle and the housing of water pump are rotationally connected; Turnbuckle is provided with nut, and the housing of nut and generator fixes.
The beneficial effect of the utility model: the utility model is used to connect the belt of water pump pulley, generator pulley and fan bracket belt pulley can automatic tension; When the height difference of engine crankshaft center and fan center is big the belt tension inequality can not take place yet; Skid, problem such as abnormal sound, be suitable for bulldozer and use.Realized the automatic tension of belt, need not artificial adjusting, guaranteed that belt tension is constant, avoided belt slippage, abnormal sound and overtension, made belt be in best tensioner state all the time.The automatic expansion tightening wheel Unit Installation is more convenient with dismounting in addition.
