Lubrication structure of babbitt alloy sliding bearing bush for speed increasing machine

Abstract

The invention discloses a lubrication structure of a babbitt alloy sliding bearing bush for a speed increasing machine. The lubrication structure comprises a lubricating oil pipe, a body through hole of the speed increasing machine, an oil trunking, oil storage grooves and babbitt alloy sliding bearing bushes, wherein the forced lubricating oil pipe is a bent pipe of 90 degrees, an oil inlet is form in one end of the forced lubricating oil pipe, and the other end of the forced lubricating oil pipe is connected to the body through hole of the speed increasing machine; the body through hole of the speed increasing machine horizontally penetrates through the body of the speed increasing machine and is connected with the oil trunking; a hole is formed in the side of the oil trunking and is respectively connected with the body through hole of the speed increasing machine and the oil storage grooves, and pinhole-shaped small holes are formed in the upper surfaces of the oil storage grooves; the babbitt alloy sliding bearing bushes are arranged above the oil storage grooves, the bodies of the babbitt alloy sliding bearing bushes are made of 45 steel, abrasion-proof babbitt alloy layers are plated on the bodies of the babbitt alloy sliding bearing bushes, needle-shaped through holes are formed in the bodies of the babbitt alloy sliding bearing bushes, and the positions of the through holes are aligned with the small holes in the tops of the oil storage grooves. The number of the through holes can be changed along with the changes of the size and the structure of the speed increasing machine. According to the lubrication structure disclosed by the invention, a pressure oil membrane of 0.15-0.2mm can be formed, the friction is reduced, and the operating efficiency of the speed increasing machine is improved.

Description

technical field [0001] The invention belongs to the field of mechanical speed-increasing lubrication, and in particular relates to a Babbitt alloy sliding bearing bush lubrication structure applied to speed-increasing machines. Background technique [0002] At present, most of the speed increasers used in various industries use rolling bearings or copper tiles. During the operation of the speed increaser, although there is a forced lubrication or cooling device, the temperature rise of the bearings when the speed increaser is running at a high speed (below 12000r / min) can be reduced. The problem has not been solved all the time. The limit speed of the existing speed increaser can only reach 3500r / min, and the efficiency of the speed increaser is low during operation. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and proposes a babbitt alloy sliding bearing pad lubrication structure applied to speed incr...
