Description
Technical field
The utility model relates to an oil hydraulic motor, is specifically related to a kind of axle and joins the outer five-pointed star radial piston hydraulic motor of oil.
Background technique
At present, oil hydraulic motor has been widely used in various engineering field, oil hydraulic motor generally refers to and carries out exporting rotary motion, and the hydraulic energy provided by oil hydraulic pump changes the energy conversion device of mechanical energy into, can be divided at a high speed and low speed two class greatly by the rated speed of oil hydraulic motor.High-speed hydraulic motor is divided into gear type, screw type and blade type substantially, and their main feature is that rotating speed is higher, rotary inertia is little and regulates highly sensitive; The main feature of low speed hydraulic motor is that discharge capacity is large, volume is large and rotating speed is low, and without the need to speed reducer; But the equal complicated structure of this two classes motor, and additional valve block is long-pending comparatively large, can not better meet user demand; In prior art, the working pressure of oil hydraulic motor is relatively low, joins oily mode based on planar oil distributing, and work under the environment that pressure is higher, copper cushion block is easy to wear up to distortion; In addition, comparatively large owing to impacting greatly, rubbing, fluid heating is serious, and the oil overheating of hydraulic system, a series of problem causing hydraulic actuator normally to work can be caused.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of axle and joining the outer five-pointed star radial piston hydraulic motor of oil, joining oily working stability, not easy to wear, improve fluid heating problem, extend the working life of oil hydraulic motor.
(2) technological scheme
Axle of the present utility model joins the outer five-pointed star radial piston hydraulic motor of oil, comprises housing; Oil distributing shaft and bent axle are installed in described housing; On housing, the first oil inlet and outlet and the second oil inlet and outlet is offered above described oil distributing shaft; The rear side of described oil distributing shaft is provided with logical food tray; Described oil distributing shaft offers static balance groove; Described logical food tray is connected with tilt cylinder cylinder body by high pressure runner; Plunger is provided with on rear side of described tilt cylinder cylinder body; Connected by bearing housing between described plunger and bent axle; Between institute's bent axle and bearing housing, bearing is installed; Connecting rod is provided with in described plunger.
Further, the outside of described bent axle is provided with end cap; Cross key is provided with below described logical food tray; Described tilt cylinder cylinder body arranged outside has stifle; The rear side of described stifle is provided with capping; The joint of described capping and bent axle is provided with oil sealing.
As preferred embodiment, described bearing is tapered roller bearing.
As preferred embodiment, the joint of described plunger and bearing housing offers osculum.
(3) beneficial effect
Compared with prior art, axle of the present utility model joins the outer five-pointed star radial piston hydraulic motor of oil, crankshaft group is formed by bent axle, bearing housing and bearing, by its Spielpassung, and produce rolling friction, greatly reduce the frictional force between plunger and bearing housing, improve the mechanical efficiency of motor further; Osculum is opened in plunger and bearing housing joint, and high pressure oil herein can produce a reaction force, makes bearing housing and plunger fitting surface play the effect of static balance, thus reduces the friction between plunger and bearing housing, and the little oil liquid temperature of frictional force can be effectively controlled; There is static balance oil groove can make to form oil film between bent axle and logical food tray, reduce friction factor and just can effectively control fluid heating problem; Oil distributing shaft has static balance oil groove, make the balance of the radial pressure acted on oil distributing shaft, the wearing and tearing of slidingsurface can be alleviated, also can leak by control gap, substantially increase the volumetric efficiency of motor like this; Connecting rod and plunger, with mating spherical surfaces, can bear greater impact power; The tapered roller bearing adopted can carry certain radial force, so more can be suitable for the environment of certain radial force and axial force work; The working pressure of current oil hydraulic motor is relatively low; join oily mode based on planar oil distributing; work under the environment that pressure is higher; copper cushion block is easy to wear up to distortion; and in the utility model, adopt the mode of axial oil distribution well to avoid these problems, also can control oil temperature rises, and makes hydraulic element can obtain certain protection; improve working environment, thus motor is improved working life.
