Problems solved by technology

Since the driving gear on the engine crankshaft not only transmits power to the water pump shaft, but also transmits power to the large plate gear on the clutch, or to the oil pump shaft, the original driving gear on the crankshaft cannot be easily changed. Therefore, the transmission ratio between the driven gear on the water pump shaft and the driving gear on the crankshaft cannot be adjusted, so the water pumping volume of the engine cannot be changed by changing the transmission ratio of the gear pair.

Abstract

Disclosed water pump modified based on integral type water pump for engines includes following structure: (1) two seal rings in excircle grooves are located on cylindrical faces in different diameters, and oil drain hole is between the said two seal rings; (2) impeller is installed on one end of water pump shaft, and bearing support is installed on the other end. Bearing on the support is seated on bearing seat in crankcase; (3) driven gear on water pump shaft is located between bearing in body of water pump and bearing in crankcase; (4) driving gear 21 and water pump driving gear 5 are installed on crankshaft, and driving gear 5 is engaged to the driven gear. The invention overcomes swing of water pump shaft, reduces abrasion between parts. Adjusting transmission ratio of gear pair can change water pumpage.

Description

technical field [0001] The invention relates to a vehicle transmission device, in particular to a water-cooled motorcycle engine water pump and a starting mechanism thereof. Background technique [0002] At present, water-cooled engine water pumps are mainly composed of water pump shaft, impeller, mechanical water seal moving ring, mechanical water seal static ring, bearings, water pump body, sealing ring, water pump cover, etc. Since the shape of the water pump body is two sections with different diameters The cylinder has 1 to 2 sealing rings on the small cylindrical surface of the same diameter, and because the diameter of the small cylindrical surface is similar to the diameter of the pump body installation hole on the crankcase cover, when the water pump body is installed on the pump body of the crankcase cover When in the hole, the oil drain orifice on the crankcase cover correspondingly matched with the small cylindrical surface will inevitably scratch the sealing rin...
