Abstract
The utility model relates to a chain wheel auxiliary mounting structure of an oil pump. The chain wheel auxiliary mounting structure comprises an oil pump body, wherein an oil pump drive shaft is arranged inside the oil pump body; the oil pump drive shaft is connected with a chain wheel through a fastening bolt; the chain wheel auxiliary mounting structure further comprises an auxiliary mounting pin; a boss is arranged on the oil pump body; the boss is close to the connecting part of the chain wheel and the oil pump body; a first pin hole is formed in the boss; a second pin hole is formed in the oil pump drive shaft; the first pin hole is coaxial with the second pin hole; the auxiliary mounting pin penetrates the first pin hole and the second pin hole. The pin holes are formed in the oil pump body and the oil pump drive shaft; the auxiliary mounting pin penetrates the first pin hole in the boss on the oil pump body and the second pin hole in the oil pump drive shaft, so that the oil pump drive shaft is fixed onto the oil pump body, and the oil pump drive shaft is prevented from rotating during the fastening process of the chain wheel bolt.
Description
Technical field
The utility model relates to oil pump technical field, is specifically related to a kind of sprocket wheel auxiliary mounting structure of oil pump.
Background technique
Oil pump is arranged in oil sump, passes through chain drive by bent axle.Sprocket wheel is bolted on oil pump live axle.Because oil pump live axle can freely rotate, so chain wheel bolt cannot be fastening.In prior art, the general comparatively frock of complexity that adopts is carried out the installation of sprocket wheel, installation process complexity, and installation efficiency is poor.
Model utility content
The purpose of this utility model is for above-mentioned technical problem, and a kind of sprocket wheel auxiliary mounting structure of oil pump is provided, to guarantee the screw-down torque of chain wheel bolt.
The technical solution adopted in the utility model is: the sprocket wheel auxiliary mounting structure of oil pump, comprise oil pump body, in oil pump body, be provided with oil pump live axle, oil pump live axle is connected with sprocket wheel by sprocket wheel clamping bolt, it is characterized in that: also comprise auxiliary mount pin; On described oil pump body, be provided with boss, described boss is near the joint of sprocket wheel and oil pump body; On boss, be provided with the first pin-and-hole, be provided with the second pin-and-hole on oil pump live axle, described the first pin-and-hole is coaxial with the second pin-and-hole; Described auxiliary mount pin is through the first pin-and-hole and the second pin-and-hole.
The beneficial effects of the utility model are: on described oil pump body and oil pump live axle, be processed with pin-and-hole, auxiliary mount pin is through the first pin-and-hole on oil pump body convex platform and the second pin-and-hole on oil pump live axle, oil pump live axle is fixed on oil pump body to oil pump drive shaft turns while preventing fastening chain wheel bolt.
