Abstract
The utility model discloses a valve disc for a hydraulic motor, and belongs to the technical field of valve discs for hydraulic motors. For solving the technical problems, the utility model provides a valve disc with a simple structure and a good using effect for a hydraulic motor. According to the technical scheme, the valve disc for the hydraulic motor is characterized in that a valve disc body is a convex cylinder, the valve disc body is radially provided with a spline hole along the axis, 6 straight holes and 6 oblique holes are uniformly formed in the circumference of the spline hole and arranged at intervals, and the valve disc body is manufactured by adopting a powder metallurgy process. The valve disc realizes positive rotation and reverse rotation through mutual conversion of an oil inlet hole and an oil return hole, and is simple in structure and good in using effect; and the valve disc is manufactured by adopting the powder metallurgy process, so that the production efficiency is greatly improved, the cost is saved, the utilization rate of a material is improved, and the valve disc can be used for large-batch production.
Description
Technical field
A kind of hydraulic motor valve disc of the utility model belongs to oil hydraulic motor valve disc technical field.
Background technique
Valve disc major part in the at present domestic oil hydraulic motor is that import is external, has plenty of and uses steel part machining to make, and cost is high, and efficient is low.
The model utility content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of simple in structure and hydraulic motor valve disc that using effect is good.
In order to solve the problems of the technologies described above, the technological scheme that adopts is: a kind of hydraulic motor valve disc, the valve disc body is the convex cylinder, and the valve disc body radially has splined hole along axis, evenly has 6 straight holes and 6 inclined holes and straight hole and inclined hole interval around the splined hole and arranges.
Described valve disc body adopts the powder metallurgical technique manufacturing.
The beneficial effect that the utility model compared with prior art has is: the utility model is realized forward and reverse by the mutual conversion of oil inlet hole and spill port, and simple in structure, using effect is good; The utility model adopts powder metallurgical technique to make, and has greatly improved manufacturing efficiency, has saved cost, has improved stock utilization, can produce in enormous quantities.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the rear view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 1.
Embodiment
Shown in Fig. 1-3, a kind of hydraulic motor valve disc of the utility model, valve disc body 1 is the convex cylinder, valve disc body 1 radially has splined hole 2 along axis, evenly has 6 straight holes 3 and 6 inclined holes 4 and straight hole 3 and inclined hole 4 intervals around the splined hole 2 and arranges.
