Abstract
The invention discloses a hydraulic single-stage planetary gear reducer. The hydraulic single-stage planetary gear reducer comprises a machine shell, a motor, a gear coupler, a sun gear, a planet gear, a hinge pin and a planet carrier, wherein the gear coupler, the sun gear, the planet gear, the hinge pin and the planet carrier are arranged inside the machine shell, the motor is connected with the sun gear through the gear coupler, the sun gear is meshed with the planet gear through a gear, the planet gear is connected with the planet carrier through the hinge pin, and the motor is a hydraulic motor. According to the special design of the hydraulic single-stage planetary gear reducer, hydraulic power is adopted; the hydraulic single-stage planetary gear reducer has the advantages of being compact in structure, long in service life, large in rated output torque and the like, and hydraulic power can be converted into mechanical power.
Description
Technical field
The present invention relates to gear reducer technical field, be specifically related to a kind of hydraulic pressure single-stage planetary gear reducer.
Background technique
Retarder is the separate transmission parts for reducing rotating speed, transferring power, increase torque.Retarder plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and in modern mechanical, application is very extensive.
Traditional kind of drive is due to the shortcoming of self, can cause be short of power, excursion is limited, impact force is excessive, layout troublesome poeration, be prone to the phenomenons such as accident, also can make the use of retarder shorten.
Summary of the invention
For address the above problem the invention discloses a kind of power foot, excursion wide, impact little, simple to operate, use safe hydraulic pressure single-stage planetary gear reducer, comprise: casing, motor, toe joint hand, sun gear, planet wheel, bearing pin, planet carrier, described toe joint hand, sun gear, planet wheel, bearing pin, planet carrier are all inner at casing, described motor is connected with sun gear by toe joint hand, described sun gear and planet wheel mesh by gear, described planet wheel is connected with planet carrier by bearing pin, and described motor is oil hydraulic motor.
The present invention adopts hydraulic power, and hydraulic power is converted into machine power, and power is sufficient, excursion is large, impact force is little, layout is simple to operate, be not prone to the phenomenons such as accident, also can make extend the working life of retarder.
Owing to adopting technique scheme, the present invention has following beneficial effect fruit:
1) compact structure, working life, very long, specified output torque was large;
2) can convert hydraulic power to machine power.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Wherein: 1-casing; 2-motor; 3-toe joint hand; 4-sun gear; 5-planet wheel; 6-bearing pin; 7-planet carrier.
Embodiment
A kind of hydraulic pressure single-stage planetary gear reducer as described in Figure 1, comprise: casing 1, motor 2, toe joint hand 3, sun gear 4, planet wheel 5, bearing pin 6, planet carrier 7, described toe joint hand 3, sun gear 4, planet wheel 5, bearing pin 6, planet carrier 7 are all in casing 1 inside, described motor 2 is connected with sun gear 4 by toe joint hand 3, described sun gear 4 meshes by gear with planet wheel 5, described planet wheel 5 is connected with planet carrier 7 by bearing pin 6, and described motor 2 is oil hydraulic motor.
Finally it should be noted that: above embodiment is only in order to illustrate the present invention and unrestricted technological scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the present invention; And all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in claim scope of the present invention.
