Abstract

The utility model discloses a cycloidal hydraulic fluid motor with wheel, which comprises oil seal cap, shell, former lateral plate, stator body and back lateral plate with seal housing. The conversion of the fluid pressure energy is accomplished by the cycloid wheel and dipyre in the seal shell which output the power by cycloid wheel that formed involute spline broach contacting with chief axis. It is provided with the advantages that the sealed and withstanding high pressure oil seal and wiper scraper seal voltage chief axis are provided on the surface between the chief axis and the oil seal cap, the block bearing between the chief axis and shell is improved into a pair of roller bearings whose two surfaces are provided with a pair of needle roller thrust bearings. The improved motor is equipped with strong radial bearing capacity and with the capacity of bearing the outer and inner axial force and the oil-pressure of 15Mpa, preventing ingress of war, adapting to high pressure, thin film, frequent starting and inverting, and the middle and the light vehicle under the hostile environment.

Description

The wheel cycloid hydraulic motor
Technical field
The utility model relates to a kind of oily cycloid hydraulic motor of axially joining, in especially a kind of being suitable for, the wheel cycloid hydraulic motor that drives of Lightweight Vehicles wheel.
Background technique
Cycloid hydraulic motor is a kind of mechanism that can be converted into mechanical energy by cycloid wheels realization hydraulic pressure, it has that the output torque is big, starting characteristic good, speed range is wide, adjustment is steady, low speed is stable, volume is little, in light weight, flexible arrangement, can be directly and advantages such as operation mechanism links to each other, be widely used in fields such as agricultural, fishery, engineering machinery, but as in, the special-purpose vehicle of certain specific function such as Lightweight Vehicles such as road sweeper, more require under the prerequisite that does not increase radial dimension, to improve radially bearing capacity; Require motor can adapt to high pressure, often startup, frequent commutation, the abominable operating mode of environment; And acting on axial force on the axle or the like to bearing inside and outside portion, existing cycloid hydraulic motor is difficult to be competent at.
Summary of the invention
Goal of the invention of the present utility model all provides in a kind of being applicable in the defective that overcomes prior art, under the Lightweight Vehicles particular job condition anti-sealing and can bear radially, the wheel cycloid hydraulic motor of axial force.
Goal of the invention of the present utility model is achieved through the following technical solutions:
A kind of wheel used cycloid hydraulic motor, forms hermetic shell by oil seal cover, housing, front side plate, rotor, back side panel that link links to each other, and case body is provided with A chamber, B chamber, inclined oil hole of air a, inclined oil hole of air b, oil through; Also be provided with 2 one-way valves on the housing; What realization hydraulic pressure can transform is interior cycloid wheel and pin post of rotor Seal cage, the transmission shaft of this cycloid wheel and axially locating, transmission shaft and the main shaft that is bearing in the housing by bearing mesh the output of composition power with involute splines, main shaft is provided with circular groove a, circular groove b and the rectangle groove of joining oil, it is characterized in that:
The junction plane of a, described output main shaft and oil seal cover is provided with high pressure resistant oil sealing and dust ring;
Block bearing between b, described main shaft and housing is a pair of needle bearing, and the main shaft two ends are provided with needle roller thrust bearing.
Being connected to of described housing and oil seal cover is embedded, and promptly the housing end face is an indent formula groove, and oil seal cover embeds to be fitted in this groove and fixes.
One-way valve on the described housing is made up of " O " RunddichtringO, unidirectional valve seat, steel ball, straight pin.
Described back side panel is provided with the sealing plug screw.
Compare with existing cycloid hydraulic motor, the utility model in, the requirement of Lightweight Vehicles particular job condition improves, selected of the supporting of the less needle bearing of outside dimension for use as main shaft, radial dimension does not increase, but radially bearing capacity improves greatly, the operating mode that makes this motor can adapt to high pressure, thin oil film and often start, frequently commutate; The application of thrust-bearing can be born outside and the axial force of internal action on axle; The setting of high pressure resistant oil sealing and dust ring, make this motor can bear 15Mpa internal oil pressure and prevent that outside foreign material from entering, the performance of anti-sealing more makes this motor can be operated in environmental pollution, the more rugged environment of dust; Housing is connected with the embedded of oil seal cover, makes the motor axial dimension shorten 20% than original structure.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Embodiment
Below in conjunction with the accompanying drawings the utility model embodiment is described in detail again.
As shown in Figure 1, the wheel cycloid hydraulic motor, by oil seal cover 37, housing 6, front side plate 26, rotor 16, back side panel 24 is formed hermetic shell, being connected to of housing and oil seal cover is embedded, be that the housing end face is processed into indent formula groove, equipped fixing by link 5 again in the oil seal cover embedded groove with it, shortened axial dimension, on the two junction plane, be provided with " O " RunddichtringO 34, housing 6 and front side plate 26, front side plate and rotor 16, be equipped with " O " RunddichtringO 14 on the junction plane of rotor and back side panel 24, and be fastenedly connected one by link 21 and Sealing 20.Housing is provided with A chamber 10, B chamber (not shown), inclined oil hole of air a7, inclined oil hole of air b11,7 uniform oil throughs 9.2 one-way valves on the housing are made up of " O " RunddichtringO 27, unidirectional valve seat 29, steel ball 28, straight pin 30.
