Abstract
The utility model relates to a novel air motor, which comprises a casing (1), and a stator (2) and a rotor (3) which are arranged in the casing (1). An air chamber (6) between the stator (2) and the casing (1) is communicated with an air outlet channel (5); a plurality of air holes (7) are formed on the part where the air chamber (6) contacts with the stator (2); an air inlet channel (4) arranged on the casing (1) is communicated with the cavity of the stator (2); and the novel air motor is characterized in that a gap (8) is left between the stator (2) arranged between the stator (2) and the casing (1), and the stator (2) is arranged between an air chamber (6) and the air outlet channel (5); a sealing ring (9) is clamped at the part where the stator (2) contacts with the casing (1); and the outer diameters at two end parts of the stator (2) tightly contact with the inner diameter of the matched part of the casing (1). The novel air motor has the advantages of skillful structure, reasonable design, low noise during operation, and high efficiency.
Description
Technical field
The utility model relates to a kind of gas motor, and especially a kind of structure is ingenious, reasonable in design, and effect height, not eccentric can effectively be lowered the temperature, the novel gas motor of noise reduction.
Background technique
The gas motor is the drive unit that many operation occasions need use, but there is following shortcoming mostly in existing gas motor: at first rely on machining accuracy to guarantee seal between stator and the housing fully, and in actual production process, because the restriction of machining condition and assembly technology, sealing effect is relatively poor, this can cause the hyperbaric chamber of motor to be connected with low-pressure cavity, the effect when reducing motor operation; Secondly, in the gas motor of existing structure, need to rely on the two contacted camber line partly to locate between stator and the housing, and the distance of this section camber line is shorter relatively, inaccurate situation therefore can occur locating; The gas motor of last conventional construction adopts the mode of in line wind, and it is abundant inadequately to cause pressurized air to expand in housing, and back pressure is excessive, can produce bigger noise when operation.
Summary of the invention
The utility model is in order to solve existing in prior technology the problems referred to above, to provide a kind of structure ingenious, reasonable in design, and noise is little during operation, the novel gas motor that effect is high.
Concrete solution of the present utility model is: a kind of novel gas motor, comprise housing 1 and be arranged at its interior stator 2 and rotor 3, be provided with air chamber 6 between stator 2 and the housing 1, with offer a plurality of pores 7 on the stator 2 of air chamber 6 contact segments, the gas-entered passageway 4 that is arranged on the housing 1 communicates with the inner chamber of stator 2, it is characterized in that: the stator 2 between described air chamber 6 and the outlet passageway 5 leaves space 8 with housing 1.
Described stator 2 is folded with seal ring 9 with housing 1 contact segment.
The external diameter at described stator 2 two end part closely contacts with the internal diameter of the partial shell 1 that matches.
The utility model is compared with prior art, has following advantage:
The utility model embodiment's novel gas motor, simple in structure, ingenious, reasonable in design, can solve the inaccurate problem in location between stator that the gas motor of embryonal structure exists and the housing, the mode that adopts the contact of wholecircle week to locate guarantees processing and installation precision; Also avoided simultaneously causing the hyperbaric chamber of motor to communicate with low-pressure cavity because of the restriction on machining condition and the assembly technology, the situation that effect reduces when making operation takes place; Simultaneously, adopt the air draft mode of loop checking installation, pressurized air is expanded in housing fully afterwards discharge, reach the purpose of abundant cooling, noise reduction.This product possesses extensive market prospects, very helps applying in the art.

Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the A portion sectional view of Fig. 2.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As Fig. 1, Fig. 2, shown in Figure 3: a kind of novel gas motor, comprise housing 1, in housing 1, be provided with the stator 2 and the rotor 3 that match, gap between stator 2 and housing 3 is an air chamber 6, on stator 2, be provided with a plurality of pores 7 with air chamber 6 contacted parts, be arranged on the intracavity inter-connection of gas-entered passageway 4 and stator 2 on the housing 1, stator 2 between air chamber 6 and the outlet passageway 5 leaves space 8 with housing 1, space 8 and air chamber 6 structure that is communicated as one, the gas of discharging from pore 7 just can enter outlet passageway 5 by air chamber 6 and the space 8 that is communicated with like this, and finally discharges gas motor outside; In stator 2 and housing 1 contacted part, also be provided with seal ring 9, it can guarantee that the hyperbaric chamber of gas motor and low-pressure cavity are isolated fully, avoids taking place because of the situation that poor sealing causes effect to reduce; Two ends at stator 2, its external diameter closely contacts with the internal diameter of the housing 1 of this part, help guaranteeing the sealing of air chamber 6 so on the one hand, on the other hand because the two all has contact on whole circumference, therefore belong to wholecircle Zhou Dingwei, this orientation type is than the form good positioning effect of having only part circumferential contact location in the structure in the past, and is also safer in the gas motor operations, stable.
The working procedure of the utility model embodiment's novel gas motor is as follows: when the gas motor starting, pressurized air enters the inside of stator 2 by gas-entered passageway 4, because stator 2 only contacts herein with the inwall of housing 1, and the contact segment at the two also is provided with seal ring 9, this structure just can be effectively with the hyperbaric chamber of gas motor and low-pressure cavity is isolated fully comes, avoid the generation of rough sledding; Entering stator 2 internal compression air driven rotors 3 rotates, and in its rotation, enter air chamber 6 by pore 7, and since air chamber 6 be connected with space 8 between the stator 2 at housing 1, and space 8 communicates with outlet passageway 5, so this part pressurized air is just discharged outside the gas motor via air chamber 6, space 8 and outlet passageway 5; And owing to the two end part of stator 2 closely contact and seal with the housing 1 of the part that matches, so gas motor safety, reliable in course of action.
