Abstract
The invention discloses a single-stage planetary gear speed reducer which comprises a shell, a gear coupler, a sun gear, a planetary gear, an internal gear, a pin roll and an output shaft. The gear coupler is fixedly connected with the sun gear, the sun gear is meshed with the planetary gear, the planetary gear is connected with the output shaft through the pin roll, and the internal gear is meshed with the planetary gear. The single-stage planetary gear speed reducer is different from a traditional speed reducer, is a planetary speed reducer, and has the advantages of being large in load torque, high in speed ratio, large in starting-allowed impact load, small in size and the like.
Description
Technical field
The present invention relates to speed reducer technical field, be specifically related to a kind of single-stage planetary gear reduction unit.
Background technique
Speed reducer 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.
Tradition speed reducer drives gearwheel to reach the object of deceleration by small gear, but this traditional speed reducer bearing torque is limited, and speed ratio is little, and startup impact allowance load is little, and volume is large, due to these effects limit the application of speed reducer in modern mechanical.
Summary of the invention
For addressing the above problem, the invention discloses a kind of single-stage planetary gear reduction unit, comprise: casing, toe joint hand, sun gear, planet wheel, internal gear, bearing pin, output shaft, described toe joint hand, sun gear, planet wheel, internal gear, output shaft are all inner at casing, described toe joint hand and sun gear are affixed, described sun gear and planet wheel engagement, described planet wheel is connected by bearing pin with output shaft, described internal gear and planet wheel engagement.
The present invention is different from traditional speed reducer, and power is by sun gear, and sun gear drives planet wheel, planet wheel can be in internal gear rotation around sun gear revolution, the revolution of planet wheel drives output shaft rotation, such speed reducer machine bearing torque is large, speed ratio is large, starts impact allowance load large, and volume is little.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Wherein: 1 casing; 2-toe joint hand; 3-sun gear; 4-planet wheel; 5-internal gear; 6-bearing pin; 7-output shaft.
Embodiment
A kind of single-stage planetary gear reduction unit as shown in Figure 1, comprise: casing 1, toe joint hand 2, sun gear 3, planet wheel 4, internal gear 5, bearing pin 6, output shaft 7, described toe joint hand 2, sun gear 3, planet wheel 4, internal gear 5, bearing pin 6, output shaft 7 are all in casing 1 inside, described toe joint hand 2 is affixed with sun gear 3, described sun gear 3 and planet wheel 4 engagements, described planet wheel 4 is connected by bearing pin 6 with output shaft 7, described internal gear 5 and planet wheel 4 engagements.
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.
