Abstract
The utility model discloses a double needle hydraulic motor, which consists of an output shaft, an anti-dust ring, a skeleton oil seal, a front cover, a bearing housing, a coupling, a stator rotor pair, a serial gear, a rear valve body, a seal ring and a bearing. The double needle hydraulic motor is characterized in that the bearing housing is arranged on the front end of the stator rotor pair, the bearing is arranged inside the bearing housing, the front cover is arranged on the front end of the bearing housing, the output shaft is arranged inside the front cover, the anti-dust ring and the skeleton oil seal are arranged between the output shaft and the front cover, the coupling is arranged on the rear end of the output shaft, the serial gear is arranged inside the stator rotor pair, the rear valve body is arranged on the rear end of the stator rotor pair, and the seal ring is arranged between the rear valve body and the stator rotor pair. The double needle hydraulic motor has the beneficial effects that by the adoption of the design of a double gear, adverse effect on the performance of the stator rotor pair due to unperfect precision of a long gear is avoided, and the performance of an overall hydraulic motor is guaranteed.
Description
Technical field
The utility model belongs to the hydraulic machinery technical field, says more specifically a kind of double pin oil hydraulic motor.
Background technique
At present, the oil hydraulic motor of prior art, particularly the cover of 1000 milliliters of discharge capacity stator-rotator pairs of BMT motor is longer, its supporting pin tooth is because long and often do not reach technical requirements, namely not good because of its long pin-teeth precision, and affect the stator-rotator pair performance, thus affect the overall performance of oil hydraulic motor.
Summary of the invention
In order to address the above problem, the utility model provides a kind of double pin oil hydraulic motor, its concrete scheme is: described double pin oil hydraulic motor is by output shaft, dust ring, outside framework oil seal, protecgulum, bearing housing, coupling, stator-rotator pair, the tandem needle tooth, rear valve body, seal ring, bearing forms, the front end that it is characterized in that stator-rotator pair arranges bearing housing, the inside of bearing housing arranges bearing, the front end of bearing housing arranges protecgulum, the inside of protecgulum arranges output shaft, dust ring and outside framework oil seal are set between output shaft and the protecgulum, the rear end of output shaft arranges coupling, the inside of stator-rotator pair arranges the tandem needle tooth, the rear end of stator-rotator pair arranges rear valve body, between rear valve body and the stator-rotator pair seal ring is set.
The beneficial effects of the utility model are that double pin oil hydraulic motor adopts double pin tooth design, namely the short pin-teeth with two series connection replaces original long pin-teeth, and stator and rotor are still integral body, get rid of the adverse effect to the stator-rotator pair performance that produces because the long pin-teeth precision is not good, guaranteed the overall performance of oil hydraulic motor.
Description of drawings
Accompanying drawing is structural representation of the present utility model; In the accompanying drawing:
1. output shaft, 2. dust ring, 3. outside framework oil seal, 4. protecgulum, 5. bearing housing, 6. coupling, 7. stator-rotator pair, 8. tandem needle tooth, 9. rear valve body, 10. seal ring, 11. bearings.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail, so that the public grasps implementation methods of the present utility model better, the utility model specific embodiment is: described double pin oil hydraulic motor is by output shaft 1, dust ring 2, outside framework oil seal 3, protecgulum 4, bearing housing 5, coupling 6, stator-rotator pair 7, tandem needle tooth 8, rear valve body 9, seal ring 10, bearing 11 forms, the front end that it is characterized in that stator-rotator pair 7 arranges bearing housing 5, the inside of bearing housing 5 arranges bearing 11, the front end of bearing housing 5 arranges protecgulum 4, the inside of protecgulum 4 arranges output shaft 1, dust ring 2 and outside framework oil seal 3 are set between output shaft 1 and the protecgulum 4, the rear end of output shaft 1 arranges coupling 6, the inside of stator-rotator pair 7 arranges tandem needle tooth 8, the rear end of stator-rotator pair 7 arranges rear valve body 9, between rear valve body 9 and the stator-rotator pair 7 seal ring 10 is set.
The beneficial effects of the utility model are that double pin oil hydraulic motor adopts double pin tooth design, namely the short pin-teeth with two series connection replaces original long pin-teeth, and stator and rotor are still integral body, get rid of the adverse effect to the stator-rotator pair performance that produces because the long pin-teeth precision is not good, guaranteed the overall performance of oil hydraulic motor.
