Abstract

The invention relates to the technical field of lubricating grease, in particular to a transmission shaft spline lubricating grease composition and a preparation method and application thereof. The main components of the transmission shaft spline lubricating grease composition comprise base oil, a thickening agent, an antioxidant, an antirust agent and an extreme pressure anti-wear agent, whereinthe thickening agent is a composite lithium thickening agent; the viscosity of the base oil at 100 DEG C is 9-30 mm < 2 >/s; the antioxidant is an amine antioxidant and/or a phenol antioxidant; the antirust agent is barium sulfonate; the extreme pressure anti-wear agent is organic molybdenum phosphate and/or polytetrafluoroethylene; the thickening agent accounts for 10-15% of the total mass of themain components; and based on the total mass of the main components, the use amount of the extreme pressure anti-wear agent is 2.5-5%. Various properties of the transmission shaft spline lubricatinggrease composition are superior to those of products in the prior art.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a transmission shaft spline lubricating grease composition and a preparation method and application thereof. Background technique [0002] With the rapid development of the automobile industry, automobile output and product structure have also undergone great development, thus putting forward newer and higher requirements for automobile lubricating grease. The problems faced by auto parts and lubricating grease are: on the one hand, although the amount of lubricating grease used in auto parts is small, the variety and performance requirements are relatively high; Even the cost of the whole vehicle is much lower, but in recent years, due to the cost pressure of the automobile OEMs, the auto parts factories have to reduce the cost. [0003] The basic function of the drive shaft spline is to transmit torque from one transmission to another; the torque of the car engine i...
