Description
Technical field
This utility model relates to field of gears, particularly relates to a kind of noise-reducing oil pump gear。
Background technology
Gear pump is a critical component in machinery hydraulic system for conveyance fluid medium, and it relies on the high speed rotary motion pumped (conveying) medium of a pair oil pump gear。Owing to oil pump gear requires different from general mechanical drive gear job specification, during oil pump gear engagement, its sideshake is all only small with bottom clearance, the pressure medium of output is higher again, its suffered load that interacts is very big, gear shaft produced deflection deformation during work, pressure medium is more high, deforms more big。Owing to deformation causes that gear shaft worsens with bearing supporting place mated condition, promoting the aggravation of gear pump component abrasion, generation abnormal sound, dielectric leakage, pressure to decline, service efficiency reduces, and shortens working life。The continuous rotation of gear simultaneously, what the alternate stress of generation can continue acts on gear shaft, and long-term work can make material produce tired and cause axle journal fracture to cause gear pump to be scrapped。
Summary of the invention
This utility model is mainly solving the technical problems that provide a kind of noise-reducing oil pump gear, it is possible to reduces the noise and vibrations that produce when running, increases the service life。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of noise-reducing oil pump gear, including: housing, drivewheel and driven pulley it is provided with in described housing, described housing lateral symmetry offers oil-in and oil-out, the engagement place of described drivewheel and driven pulley is positioned at the middle of oil-in and oil-out, described housing is offered at least 2 sound-absorbing grooves, it is provided with acoustical cotton in described sound-absorbing groove, the inside of described housing is further opened with multiple damping trough, in described damping trough, is provided with shock absorber part。
In one preferred embodiment of this utility model, the quantity of described damping trough is 8, and the cross section of described damping trough is in sector。
In one preferred embodiment of this utility model, the quantity of described sound-absorbing groove is 2, and 2 described sound-absorbing groove claddings are arranged at the outside at drivewheel and driven pulley。
In one preferred embodiment of this utility model, the cross section of described housing is 8-shaped, and described housing is that No. 45 steel are made。
In one preferred embodiment of this utility model, described shock absorber part is damping spring。
The beneficial effects of the utility model are: this utility model noise-reducing oil pump gear, it is possible to reduce the noise and vibrations that produce when running, increase the service life。
