Abstract

The utility model discloses a pneumatic motor consisting of a cylinder, a turbine and an idler pulley. The surrounding border of the idler pulley is provided with an oblique operating vent hole. The surrounding border of the turbine is provided with a plurality of blades. The idler pulley is positioned on the turbine and both idler pulley and the turbine are positioned in the annular cylinder. The utility model converts the air pressure into a mechanical energy for revolution with the cooperation of the idler pulley and the turbine through a simpler structure, and has a compact structure under the premise of the same output power, hereby satisfying more special operating conditions.

Description

Pneumatic motor

Technical field

The utility model relates to a kind of motor, especially a kind of pneumatic motor.

Background technique

Existing motor mostly is electric motor or motor of the internal-combustion engine.Motor of the internal-combustion engine power is bigger, but the volume heaviness, and power consumption is big, but also can pollute.And electric motor totally cleans, and the volume ratio motor of the internal-combustion engine is littler, uses more flexible.But, under some certain conditions, need smaller and more exquisite motor, and guarantee to export powerful power, and the watt level of motor directly is subjected to its rotor coil and restriction unshakable in one's determination, therefore need accomplish very little, still very difficult.

Through observational study, find that air pressure can become the power that promotes machine operation, and utilizing air pressure and the motor that moves, its volume is subjected to rotor coil and iron a bit to the restriction of power unlike motor, and utilizes the motor of air pressure as power, to environment also without any pollution, clean environment firendly, energy consumption is low, the rotating speed height, power is big, and is safe in utilization and of many uses.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of pneumatic motor, can utilize air pressure to carry out work as power by simple structure, reduces the volume as motor greatly, can adapt to the restriction of more conditions.

For solving the problems of the technologies described above, the technological scheme of the utility model pneumatic motor is, comprise cylinder, turbine and guide wheel, described guide wheel week, the side margin place was provided with oblique work ventilating hole, edge around the described turbine is provided with a plurality of blades, and described guide wheel and described turbine superpose up and down and be arranged in the described ring-type cylinder.

The utility model utilizes cooperating of guide wheel and turbine, by very simple structure, air pressure is converted into the mechanical energy of rotation, and is reaching under the prerequisite of identical output power, can accomplish that volume is smaller and more exquisite, can adapt to the requirement of more particular job conditions.

Embodiment

As shown in Figure 1, the utility model pneumatic motor 2 can be installed in the shell 1, and the air communication mistake is arranged in shell 1, will drive pneumatic motor 2 rotations.

The structure of the utility model pneumatic motor as shown in Figure 2, comprise cylinder 3, turbine 5 and guide wheel 4, described cylinder 3 is a ring-type, as shown in Figure 3 and Figure 4, the structure of described guide wheel 4 such as Fig. 5, Fig. 6 and shown in Figure 7, described guide wheel 4 all side margin places are provided with oblique work ventilating hole 41, also are provided with true dip direction and the opposite balance ventilating hole 42 of described work ventilating hole 41 true dip directions on the edge of described guide wheel side 4 last week.It is identical with described work ventilating hole 41 true dip directions also to be provided with true dip direction on the edge of described guide wheel side 4 last week, but the little startup ventilating hole 43 of relative aperture work ventilating hole 41.Edge around described blade 5 is taken turns is provided with a plurality of blades 51, and the blade 51 of described turbine 5 is " people " font blade of side direction.Described guide wheel 4 superposes up and down with described turbine 5 and is arranged in the described ring-type cylinder 3.

When shell 1 has air communication out-of-date, air-flow can make turbine 5 begin rotation by starting ventilating hole 43, and air communication is crossed work ventilating hole 41 and made turbine quicken rotation afterwards, and proper functioning.Because be subjected to the effect of air-flow, turbine can be shaken with air-flow, this shake not only makes whole pneumatic motor vibration aggravate, but also can reduce the power of pneumatic motor.Also be provided with balance ventilating hole 42 on guide wheel 4, the true dip direction of balance ventilating hole 42 is opposite with the true dip direction of work ventilating hole 41, and air communication overbalance ventilation oral pore 42 can be offset original shake, thereby it is more steady to make that pneumatic motor work gets.The blade of turbine 5 is " people " font, can improve the service behaviour of pneumatic motor greatly so that turbine is exported bigger power.

Claims

1. pneumatic motor, it is characterized in that, comprise cylinder, turbine and guide wheel, described guide wheel week, the side margin place was provided with oblique work ventilating hole, edge around the described turbine is provided with a plurality of blades, and described guide wheel and described turbine superpose up and down and be arranged in the described ring-type cylinder.

2. pneumatic motor according to claim 1 is characterized in that, also is provided with true dip direction and the opposite balance ventilating hole of described work ventilating hole true dip direction on the edge of described guide wheel side last week.
