Description

Air bearing motor

Technical field

The utility model relates to motor design field more particularly to air bearing motors.

Background technique

Motor, also known as starter.By hot-wire coil, the Forced rotation band mechanical starter shaft in magnetic field rotates for it, shaft On pinion gear drive engine flywheel rotation, to drive crank rotation.

Air motor is prime mover using compressed air as working media, it is the expansion using compressed gas, Pressure energy is converted to the power device of mechanical energy.The gas motor of all kinds of patterns although structure is different, have any different by working principle, but big Most gas motors have the disadvantages that

It cannot achieve stepless speed regulation, can not realize that rotating forward and reversion, vibrated, high temperature, electromagnetism, radiation etc. influence, no It is useful in severe working environment, is difficult to work normally under the unfavorable conditions such as inflammable, explosive, high temperature, vibration, humidity, dust.

Utility model content

The purpose of this utility model is to provide air bearing motors, effectively solution above-mentioned technical problem.

Effectively to solve above-mentioned technical problem, the technical solution that the utility model is taken is as follows:

Air bearing motor, including a main structure body, the main structure body are intracavitary by front cover and rear cover composing type chamber, Yu Suoshu type Equipped with shaft, graphite and collector ring are equipped between the shaft and the front cover, the front cover and rear cover junction are equipped with magnet Circle and neodymium-iron-boron iron ring.

Particularly, the graphite-filled formula is set between the shaft and the collector ring.

Particularly, it is covered after described and is respectively equipped with braking stomata, air bearing stomata and brake stomata.

Particularly, the rear cover is made of back shroud and rear decorative cover.

The utility model has the following beneficial effects: the air bearing motor of the utility model, stepless speed regulation, if control intake valve or The aperture of exhaust valve controls the flow of compressed air, is just adjustable the output power and revolving speed of motor.Adjusting can be reached to turn The purpose of speed and power；Can rotate forward can also invert, and can have with instantaneous reverse in the ability that can be instantaneously raised to full speed, Work safety, not vibrated, high temperature, electromagnetism, radiation etc. influence, suitable for severe working environment, inflammable, explosive, high temperature, It can work normally, starting torque with higher, can directly be started with load under the unfavorable conditions such as vibration, humidity, dust, Easy to operate, Maintenance and Repair, which are easier to gas motor, has structure simple, and small in size, light-weight, horsepower is big, and manipulation is easy, maintenance It is convenient, medium, the difficulty in unavailability are used air as, used air is not required to handle, and is put into pollution-free in atmosphere, compression Air can be with centralizedly supply, long-distance sand transport.

The utility model is described in detail with reference to the accompanying drawing.

Detailed description of the invention

Fig. 1 is air bearing motor complete machine structure schematic diagram described in the utility model.

Fig. 2 is air bearing motor sectional view described in utility model.

Fig. 3 is air bearing motor configuration exploded view described in the utility model.

Specific embodiment

Embodiment 1:

As shown in Figure 1-3, air bearing motor configuration setting provided in this embodiment:

Air bearing motor, including a main structure body 1, the main structure body 1 is by 3 composing type chamber 4, Yu Suoshu of front cover 2 and rear cover It is equipped with shaft 5 in type chamber 4, graphite 6 and collector ring 7, the front cover 2 and rear cover 3 are equipped between the shaft 5 and the front cover 2 Junction is equipped with magnet circle 8 and neodymium-iron-boron iron ring 9.

6 filled type of graphite is set between the shaft 5 and the collector ring 7.System is respectively equipped on the rear cover 3 Take offence hole 11, air bearing stomata 12 and brake stomata 10.The rear cover 3 is made of back shroud 32 and rear decorative cover 31

Technical scope is as follows:

Stepless speed regulation controls the flow of compressed air, is just adjustable horse as long as the aperture of control intake valve or exhaust valve The output power and revolving speed reached.It can achieve the purpose that adjust revolving speed and power；Can rotate forward can also invert, and can be instantaneous Commutation has in the ability that can be instantaneously raised to full speed, work safety, and not vibrated, high temperature, electromagnetism, radiation etc. influence, be suitable for Severe working environment can work normally under the unfavorable conditions such as inflammable, explosive, high temperature, vibration, humidity, dust, have compared with High starting torque can be started directly with load, and easy to operate, Maintenance and Repair, which are easier to gas motor, has structure simple, body Product is small, and light-weight, horsepower is big, and manipulation is easy, easy to maintenance, uses air as medium, the difficulty in unavailability, used sky Gas is not required to handle, and is put into pollution-free in atmosphere, and compressed air can be with centralizedly supply, long-distance sand transport.

The utility model is not limited to the above embodiment, it is all using structure similar to the utility model and its method come real All embodiments of existing the utility model aim are within scope of protection of the utility model.
