Description

A kind of piston type pneumatic motor air distributing device
Technical field
The utility model relates to a kind of pneumatic motor air distributing device, and what be specifically related to is a kind of piston type pneumatic motor air distributing device.
Background technique
Piston type pneumatic motor adopts pressurized air to be the energy, the gas discrepancy groove that gas is put by distributing valve, and through the intake and exhaust channel be arranged in housing, be assigned to cylinder, promote piston movement, piston is passed to bent axle again and exported.
The performance of piston type pneumatic motor is mainly reflected in rotating speed and moment of torsion and air consumption, and when air pressure is constant, the factor affecting the properties of motor concentrates on: component precision is not high, and the frictional force between crucial transmission part is large.Existing pneumatic motor adopts air distributing device usually, be assemblied in copper sheathing by distribution spool, the performance of motor is have impact on from amechanical angle, and copper sheathing and distribution valve body also can constantly wear and tear in long time running, constantly reduce the performance of motor, client is safeguarding pneumatic motor, generally all recopper cover, distribution spool will be followed, accompany gas valve core, copper sheathing, distribution valve body three parts production time long, up-to-standard rate is low, and cost compare is high.To improve the progress of component further, need increase the input of high-precision process equipment and high-precision product Inspection equipment, input ratio is larger.Existing pneumatic motor is so the frictional force reduced between transmission part is vital.
Model utility content
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: a kind of piston type pneumatic motor air distributing device, comprise bearing, exhaust cap, exhaust cap bolt, exhaust cap screw, distribution spool, distribution valve body, distribution valve body bolt, distribution valve body screw, inlet hole, described exhaust cap both sides are provided with exhaust cap screw, in described exhaust cap screw, exhaust cap bolt is installed, described exhaust cap bolt is arranged on distribution valve body away from one end of nut, described distribution valve body side is provided with distribution valve body screw, distribution valve body bolt is installed in described distribution valve body screw, described distribution valve body is provided with inlet hole away from distribution valve body screw side, described distribution spool is arranged on distribution valve inner, between described distribution spool and distribution valve body, bearing is installed.
Further, described bearing is provided with 4.
Further, described exhaust cap is connected with distribution valve body spiral by exhaust cap bolt.
The beneficial effects of the utility model are: the utility model reduces frictional force, increase the power of motor, reduce customer care cost, also the impact of the performance on motor is greatly reduced, extend the working life of motor, client, when safeguarding, only needs to change bearing, compares also lower relative to replacing copper sheathing, distribution valve body cost.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is a kind of pneumatic motor air distributing device structural representation described in the utility model.
Number in the figure illustrates: 1, exhaust cap, 2, exhaust cap screw, 3, exhaust cap bolt, 4, distribution valve body, 5, distribution valve body screw, 6, distribution valve body bolt, 7, inlet hole, 8, distribution spool, 9, bearing.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
With reference to shown in Fig. 1, the utility model provides a kind of technological scheme: a kind of piston type pneumatic motor air distributing device, comprise bearing 9, exhaust cap 1, exhaust cap bolt 3, exhaust cap screw 2, distribution spool 8, distribution valve body 4, distribution valve body bolt 6, distribution valve body screw 5, inlet hole 7, exhaust cap 1 both sides are provided with exhaust cap screw 2, in exhaust cap screw 2, exhaust cap bolt 3 is installed, exhaust cap bolt 3 is arranged on distribution valve body 4 away from one end of nut, distribution valve body 4 side is provided with distribution valve body screw 5, distribution valve body bolt 6 is installed in distribution valve body screw 5, distribution valve body 4 is provided with inlet hole 7 away from distribution valve body screw 5 side, it is inner that distribution spool 8 is arranged on distribution valve body 4, and bearing 8 is installed between distribution valve body 4, bearing 8 is provided with 4, exhaust cap 1 is connected with distribution valve body 4 spiral by exhaust cap bolt 3, easy disassembly distribution valve body 4 and exhaust cap 1, be easy to change bearing 9.
The working principle of the present embodiment is as follows: power source pressurized air passes through distribution part by distribution spool 7, have employed bearings distribution spool 7, distribution spool 7 does not contact with distribution valve body 4, make to be assigned to motor piston chamber successively, produce thrust, promote the motion of piston, drivening rod throw crank axle circular movement, realize the output shaft motion acting of motor.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
