Abstract
The utility model discloses a pneumatic motor with double air inlets. The pneumatic motor mainly comprises a housing, an air pump and a connecting base, wherein the air pump comprises a pump body, a pneumatic rotor, blades, a front end cover and a rear end cover; the blades are inserted into a slot of the pneumatic rotor; the front end cover is arranged at the front end of the pump body; the rear end cover is arranged at the rear end of the pump body; the two air inlets are formed in the rear end cover of the air pump and are arranged in a manner of a 74-degree included angle; an exhaust vent is formed in the lateral wall of the housing; and the blades inserted into the slot of the pneumatic rotor is made of brass materials. The pneumatic motor is compact in structure; three gas vents are formed in the motor, wherein two of the gas vents are the air inlets, and the other gas vent is the exhaust vent, so that the motor stably operates, and an air pump can not be deadly locked in the operational process. In addition, the blades made of the brass materials have stronger toughness and abrasive resistance than the conventional blades made of glass fiber epoxy cloth plates.
Description
Technical field
The utility model relates to pneumatic motor, and what be specifically related to is a kind of compact structure, the two inlet hole pneumatic motors that operate steadily.
Background technique
Pneumatic motor is the power engine take pressurized air as working medium, and it is the expansion that utilizes pressurized gas, pressure energy is converted to the power plant of mechanical energy; Generally formed by front cover, rear end cover, Pneumatic rotor, air pump and shell.
Existing traditional pneumatic motor, owing to only be provided with an inlet hole on the motor, an exhaust port, so when the gas expansion for doing work in the motor is maximum, gas is not in time discharged, and motor remains in operation, and causes the pressurized gas part gas energy that enters in the motor to be cancelled, and then so that motor rotary speed reduces even the phenomenon that is stuck.
In addition, in existing traditional pneumatic motor, its blade that is plugged on the Pneumatic rotor is comprised of glass yarn epoxy cloth plate material, and the shortcoming that this material exists is a little less than the toughness, and is not wear-resisting, needs often to change blade, thereby causes the increase of cost.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of compact structure, the two inlet hole pneumatic motors that operate steadily.
The utility model is achieved through the following technical solutions: two inlet hole pneumatic motors mainly are comprised of shell, air pump and connecting base; Described air pump comprises the pump housing, Pneumatic rotor, be plugged in blade in the Pneumatic rotor slot, be installed in the front cover of pump housing front end and be installed in the rear end cover of pump housing rear end; It is characterized in that: the rear end cover of air pump is provided with two inlet holes, and these two inlet holes are that modes with 74 degree angles arrange, and side wall of outer shell is provided with an exhaust port, and the described blade that is plugged in the Pneumatic rotor slot is comprised of brass material.
The intracardiac radial ball bearing that is respectively equipped with in described front cover and the rear end cover, and front cover and rear end cover couple together by elastic cylindrical pin and the pump housing respectively, rear end cover by bolt-locking on shell.
Air pump is established in the enclosure and by bolton and is installed on the connecting base.
The beneficial effects of the utility model embody and to be: the utility model compact structure, and by three gas ports are set at motor, two inlet holes wherein, an exhaust port makes motor operation steady, and it is stuck in running air pump can not occur; In addition, brass material blade is stronger than the blade toughness of traditional glass silk epoxy fabric swatch material, has more wear resistance.

Embodiment
To shown in Figure 6, two inlet hole pneumatic motors mainly are comprised of shell 6, air pump 2 and connecting base 1 such as Fig. 1; Described air pump 2 comprises the pump housing 21, Pneumatic rotor 23, be plugged in blade 24 in Pneumatic rotor 23 slots 231, be installed in the front cover 22 of the pump housing 21 front ends and be installed in the rear end cover 4 of the pump housing 21 rear ends; The rear end cover 4 of air pump 2 is provided with two inlet holes (41,42), and these two inlet holes (41,42) are to arrange in 74 modes of spending angles, shell 6 sidewalls are provided with an exhaust port 5, and the described blade 24 that is plugged in Pneumatic rotor 23 slots 231 is comprised of brass material.
Intracardiacly in described front cover 22 and the rear end cover 4 be respectively equipped with radial ball bearing 7, and front cover 22 and rear end cover 4 couple together by elastic cylindrical pin 8 and the pump housing 21 respectively, rear end cover 4 by bolt-locking on shell 6.
Be separately installed with air inlet nozzle 3 on two inlet holes (41,42) on the described rear end cover 4, on the exhaust port 5 of shell 6 exhaust nozzle 9 be installed.
The utility model compact structure, motor operation is steady.In the working procedure, Pneumatic rotor is not easy to be stuck, and blade employing brass material formation, and is more wear-resisting than traditional glass yarn epoxy fabric swatch material, longer service life, thus reduced the raw material user cost.
