Technical field
The utility model relates to retarder technical field, specifically a kind ofly realizes the adjustable planetary gear speed-reduction transmission device of reduction speed ratio between input block sun gear and output block planet carrier.
Background technique
Retarder plays coupling rotating speed and transmitting torque between prime mover and working machine or actuator, and plane table thermoconductivity meter is a kind of speed reduction gearing being widely used in modern mechanical.Common plane table thermoconductivity meter only has planet wheel, input block sun gear and output block planet carrier to rotate, and external toothing is fixed, so the reduction speed ratio between input block sun gear and output block planet carrier also just immobilizes.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, and a kind of adjustable planetary gear speed-reduction transmission device of reduction speed ratio between input block sun gear and output block planet carrier of realizing is provided.
The purpose of this utility model solves by the following technical programs:
A kind of planetary gear speed-reduction transmission device, comprise ring gear, planet wheel, as the sun gear of this transmission device input block and as the planet carrier of output block, planet wheel is intermeshing with sun gear and ring gear respectively, and planet carrier is arranged on planet wheel, it is characterized in that: the outer surface of described ring gear is provided with conductor ring, the outside of conductor ring is provided with the permanent magnetism adjustable claw that can shrink or open.
Described permanent magnetism adjustable claw swings to shrink or open along the fixing pin at its middle part.
Described permanent magnetism adjustable claw is splayed shape.
Described conductor ring is fixedly installed on the outer surface of ring gear.
The utility model has the following advantages compared to existing technology:
The utility model swings along the fixing pin at its middle part under control mechanism effect by splay permanent magnetism adjustable claw, to change the distance between conductor ring and permanent magnetism adjustable claw, regulate the rotational speed of ring gear, realize the adjusting of transmitting torque and speed between input block sun gear and output block planet carrier.
Compact structure of the present invention, has realized the step-less adjustment of input output reduction speed ratio, suitable promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-sun gear; 2-planet wheel; 3-planet carrier; 4-ring gear; 5-conductor ring; 6-permanent magnetism adjustable claw; 7-fixing pin.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 1: a kind of planetary gear speed-reduction transmission device, comprise ring gear 4, planet wheel 3, as the sun gear 1 of this transmission device input block and as the planet carrier 3 of output block, planet wheel 2 is intermeshing with sun gear 1 and ring gear 4 respectively, planet carrier 3 is arranged on planet wheel 2, outer surface at ring gear 4 is fixed with conductor ring 5, conductor ring 5 is followed ring gear 4 and is together rotated, the outside of conductor ring 5 is provided with the splay permanent magnetism adjustable claw 6 that can shrink or open, permanent magnetism adjustable claw 6 swings to shrink or open along the fixing pin 7 at its middle part under control mechanism effect, to change the distance between conductor ring 5 and permanent magnetism adjustable claw 6, regulate the rotational speed of ring gear 4, realize the adjusting of transmitting torque and speed between input block sun gear 1 and output block planet carrier 3.
When planetary gear speed-reduction transmission device of the present utility model uses: when permanent magnetism adjustable claw 6 is shunk, distance between conductor ring 5 and permanent magnetism adjustable claw 6 reduces, between conductor ring 5 and permanent magnetism adjustable claw 6, transmitting torque and active force increase, ring gear 4 will be braked locked, and input block sun gear 1 and output block planet carrier 3 are by the reduction speed ratio running by design; When permanent magnetism adjustable claw 6 is opened, distance between conductor ring 5 and permanent magnetism adjustable claw 6 increases, between conductor ring 5 and permanent magnetism adjustable claw 6, transmitting torque and active force reduce, ring gear 4 is by unfettered free to rotate, under the driving of sun gear 1, ring gear 4 rotates freely, and the rotating speed of planet carrier 3 becomes 0.
The utility model swings by splay permanent magnetism adjustable claw 6 fixing pin 7 along its middle part under control mechanism effect, to change the distance between conductor ring 5 and permanent magnetism adjustable claw 6, regulate the rotational speed of ring gear 4, realize the adjusting of transmitting torque and speed between input block sun gear 1 and output block planet carrier 3; This planetary gear speed-reduction transmission structures is compact, has realized the step-less adjustment of input output reduction speed ratio, suitable promoting the use of.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technological scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
