Abstract
The utility model discloses a single-stage planetary gear speed reducer which comprises a shell, a tooth coupling, a sun wheel, a planetary wheel, an inner gear, a pin shaft and an output shaft, wherein the tooth coupling is fixedly connected with the sun wheel; the sun wheel is engaged with the planetary wheel; the planetary wheel is connected with the output shaft through the pin shaft; the inner gear is engaged with the planetary wheel. The single-stage planetary gear speed reducer is different from a conventional speed reducer and has the advantages of large bearing torque, high speed ratio, large start-allowed impact load, small size and the like.
Description
Technical field
The utility model relates to speed reducer technical field, is 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.
Model utility content
For addressing the above problem, the utility model 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 in casing inside, described toe joint hand and sun gear are affixed, described sun gear engages with planet wheel, and described planet wheel is connected by bearing pin with output shaft, and described internal gear engages with planet wheel.
The utility model is different from traditional speed reducer, power is by sun gear, sun gear drives planet wheel, planet wheel can be in internal gear rotation revolving round the sun around sun gear, the revolution of planet wheel drives output shaft rotation, and such speed reducer machine bearing torque is large, and speed ratio is large, start impact allowance load large, volume is little.
Brief description of the drawings
Fig. 1 is sectional view of the present utility model.
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 is all in casing 1 inside, described toe joint hand 2 is affixed with sun gear 3, described sun gear 3 engages with planet wheel 4, described planet wheel 4 is connected by bearing pin 6 with output shaft 7, and described internal gear 5 engages with planet wheel 4.
Finally it should be noted that: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model 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 utility model; And all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in claim scope of the present utility model.
