Embodiment Construction

[0010] Such as figure 1 It is a structural schematic diagram of the present invention, an oil pump gear, including a ring gear 1, a transmission shaft 2, an elastic pin 3, a gear tooth 4 and a chamfer 5, the ring gear 1 and the transmission shaft 2 are connected by an elastic pin 3, and the ring gear 1 Gear teeth 4 are provided on the top, and chamfers 5 are provided on the gear teeth 4. The gear teeth 4 are twisted obliquely and distributed along the circumference of the ring gear 1 in a helical structure.

[0011] When in use, insert the elastic pin 3 into the pin hole of the ring gear 1 and the transmission shaft 2, so that the ring gear 1 is fixedly connected with the transmission shaft 2, and several gear teeth 4 are distributed along the circumference of the ring gear 1, and the gear teeth 4 are oblique The twisted gear teeth are distributed along the circumference to form a helical structure, and the four sides of the gear teeth 4 have chamfers 5 . This kind of oil pum...

Abstract

The invention relates to the technical field of gears and especially relates to a lubricating oil pump gear. The lubricating oil pump gear comprises a gear ring, a transmission shaft, a resilient pin, gear teeth and chamfers. The gear ring is connected to the transmission shaft by the resilient pin. The gear ring is provided with the gear teeth. The gear teeth are provided with the chamfers. The gear teeth twist obliquely and are uniformly distributed along the periphery of the gear ring to form a helical structure. The lubricating oil pump gear has the advantages of strong versatility, simple structure, use convenience, small processing difficulty, short process period, stable quality, high material utilization rate, high transmission stability, high wear resistance, long gear service life, good rotation flexibility in work, stable lubricating oil pump output pressure, good interchangeability and good feasibility.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to an oil pump gear. Background technique [0002] The existing oil pump gear pressure angle is small, the machining is difficult, the undercut phenomenon is serious, the production efficiency is low, the process cycle is long, the quality stability is poor, the material utilization rate is relatively low, and the wear resistance is relatively low due to the transmission torque during work. Poor, shorten the service life of the oil pump gear. Contents of the invention [0003] In order to overcome the disadvantages of the existing oil pump gear such as high processing difficulty, low production efficiency, long process cycle, poor stability, poor wear resistance and short service life, the invention provides an oil pump gear. [0004] The technical solution adopted by the present invention to solve the technical problem is: an oil pump gear, including a ring gear, a transmission sh...
