the wheel shaft is fixed with the telescopic end of the elastic telescopic mechanism;
the pinch roller is rotatably sleeved on the wheel shaft through a bearing. Through adopting above-mentioned scheme, press by the pinch roller and touch on chain or hold-in range, when chain or hold-in range pulling force increase, elasticity telescopic machanism will contract back, otherwise, when chain or hold-in range pulling force reduce, elasticity telescopic machanism will stretch out to the effect that compresses tightly of self-adjusting pinch roller pair chain or hold-in range makes chain or hold-in range be in best elasticity state.
Preferably, the side plate is provided with a strip-shaped connecting hole, and the connecting plate is provided with a fixing hole corresponding to the connecting hole; the fastener comprises a bolt and a nut, and a screw rod of the bolt sequentially penetrates through the fixing hole and the connecting hole to be connected with the nut. Through adopting above-mentioned scheme, be convenient for adjust the position of support and pinch roller.
Preferably, the elastic telescopic mechanism comprises two telescopic rods, each telescopic rod comprises an outer rod and an inner rod, the outer rods are fixed to the mounting plate, one end of each inner rod is slidably arranged inside the outer rod, the end of each inner rod is connected with a supporting spring, and the wheel shafts are fixed between the other ends of the two inner rods.
Preferably, the pinch roller is a double-row chain wheel with an integrated structure. Through adopting above-mentioned scheme, make pinch roller can cooperate with double chain engagement.
Preferably, a reinforcing block is connected between the two outer rods. Through adopting above-mentioned scheme, improve the steadiness of two telescopic links.
The utility model has the advantages and beneficial effects that: the pressing device for the rotating wheel transmission mechanism is reasonable in structure, enables a chain or a synchronous belt to be in the optimal tightness state, and achieves accurate control over tightness of the chain or the synchronous belt.
