Abstract
The utility model provides an oil pump shaft inner rotor component relating to an oil pump component in particular to the oil pump shaft inner rotor component consisting of an inner shaft, a pump shaft and a pin. The inner rotor covers the bump shaft provided with a through hole across which is embedded with the pin, the two ends of which are exposed outside of the through hole. The utility model is characterized in that the corresponding position of the inner rotor and the pin is provided with a pin groove in which the end exposed outside is embedded. The utility model is not provided with a through hole on the thin wall of the inner rotor but is provided with the pin groove on the end surface, thus greatly improving the overall strength of the inner rotor and avoiding the fragmentation when the torque moment is transmitted. And also because the utility model does not need riveting and processing on the inner rotor surface, so the surface is smooth and has a small rotating friction.
Description
Affiliated technical field
The utility model relates to a kind of oil pump assembly, particularly oil pump pump shaft internal rotor assembly.
Background technique
Existing oil pump pump shaft internal rotor assembly is made up of internal rotor, pump shaft and pin.Internal rotor is enclosed within on the pump shaft.On the axial plane of pump shaft, offer a through hole along direction perpendicular to the pump shaft axis, corresponding to the thin-walled position of through hole, also offer two through holes on the internal rotor sidewall.Pin is in the through hole of internal rotor and pump shaft, and the two ends of pin are fixedly connected by riveted way and internal rotor.There are two big defectives in this existing oil pump pump shaft internal rotor assembly: the first, owing on the thin position of internal rotor sidewall, opened two through holes, therefore the bulk strength of internal rotor self has been subjected to bigger weakening, makes internal rotor in the process of transmitting torque, easily produces cracked; It two is, during riveted joint the burr of drift easily cause rotate between internal rotor and the external rotor dumb.
Summary of the invention
The purpose of this utility model is to provide a kind of internal rotor intensity height, and is not easily broken, and the shape face is level and smooth, the oil pump pump shaft internal rotor assembly that pivoting friction is little.
Technical solution of the present utility model is: oil pump pump shaft internal rotor assembly is made up of internal rotor, pump shaft and pin, internal rotor is enclosed within on the pump shaft, on pump shaft, be provided with a through hole, pin is through in the through hole, expose outside the through hole at the two ends of pin, it is characterized in that: with the pin corresponding position, offer cotter way on the internal rotor, the exposed junction of pin is embedded in the cotter way.
The utility model is not owing to offer through hole at internal rotor thin-walled place, but offers cotter way in the end, so the internal rotor bulk strength significantly improves, and during transmitting torque, cracked phenomenon can not occur.Needn't rivet processing in inner rotor face owing to the utility model again, so its shape face is level and smooth, pivoting friction is little.
