The utility model discloses gear for hydraulic pump, the gear design has ring channel and lightening hole, makes it at little, little, the speed stabilization of vibration of transmission in -process load, be equipped with the helical tooth on barrel and the rim plate, can reduce the wearing and tearing between the gear, avoid becoming flexible between the gear, seted up the centre bore on the barrel, the centre bore surface is equipped with anti -corrosion coating, can avoid corroding, carries the life of high tooth wheel.
Description
Technical field
This utility model relates to gear technique field, particularly relates to a kind of hydraulic pump gear.
Background technology
Hydraulic pump is the dynamical element of hydraulic system, and its effect is the pressure energy that the mechanical energy of prime mover is converted into liquid.Hydraulic pump refers to the oil pump in hydraulic system, and it provides power to whole hydraulic system.Gear is the internal common gearing parts arrived of hydraulic pump.Existing hydraulic pump gear heavier-weight, gear vibrates relatively big in the course of the work, produces substantial amounts of noise when causing work, and the abrasion between gear can be made for a long time relatively big, and loosening occurs in transmission, thus has influence on the normal work and use life-span of gear.
Utility model content
The purpose of this utility model is contemplated to overcome the defect of above-mentioned hydraulic pump gear, it is provided that a kind of load is little, it is little, lightweight to vibrate, the hydraulic pump gear of length in service life.
Solve the technical problem that required by this utility model and can be achieved through the following technical solutions:
A kind of hydraulic pump gear, including cylinder, is the wheel disc of antirust treatment outside described cylinder, described wheel disc surrounding is along being evenly distributed with helical tooth, described cylinder is respectively arranged at two ends with centre bore, have rotating shaft and centre bore with the use of, one end of described cylinder is evenly distributed with helical tooth.
Further, described sheave surface offers cannelure.
Further, lightening hole is offered in described cannelure.
Further, described lightening hole has multiple, is evenly distributed on wheel disc.
Further, described central aperture surface is provided with corrosion-resistant coating.
The beneficial effects of the utility model: a kind of hydraulic pump gear, design of gears has cannelure and lightening hole so that it is load is little in transmission process, vibrate little, stabilization of speed；Cylinder and wheel disc are provided with helical tooth, can reduce the abrasion between gear, it is to avoid loosening between gear；Offering centre bore on cylinder, central aperture surface is provided with corrosion-resistant coating, can avoid corrosion, improves the service life of gear.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, this utility model is expanded on further.
When being embodied as, in conjunction with Fig. 1-3, a kind of hydraulic pump gear, including cylinder 1, is the wheel disc 2 of antirust treatment outside cylinder, and wheel disc 2 surrounding is along being evenly distributed with helical tooth 3.Cylinder 1 is respectively arranged at two ends with centre bore 4 and centre bore 7, have rotating shaft and centre bore 4 and centre bore 7 with the use of, one end of cylinder 1 is evenly distributed with helical tooth 5.
In order to alleviate the weight of gear, offer cannelure 8 on wheel disc 2 surface.Can offer lightening hole 6 in cannelure 8, lightening hole 6 can have multiple, be evenly distributed on wheel disc.
In order to reduce the corrosion of gear, improve the service life of gear, be provided with corrosion-resistant coating at centre bore 4 and centre bore 7 surface.
A kind of hydraulic pump gear, design of gears has cannelure and lightening hole so that it is in transmission process, load is little, vibrate little, stabilization of speed；Cylinder and wheel disc are provided with helical tooth, can reduce the abrasion between gear, it is to avoid loosening between gear；Offering centre bore on cylinder, central aperture surface is provided with corrosion-resistant coating, can avoid corrosion, improves the service life of gear.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
