Abstract
The utility model relates to a speed reducer whose one end of the output shaft forms a cylinder shape, an annular gear is fixed in the output shaft, and an input shaft with a central gear is connected together with the output shaft through a needle bearing. A planet gear is installed on the spoke of a brake wheel through the shaft of the planet gear, and the brake wheel is installed on the input shaft through a bearing; a brake is installed on the outer side of the brake wheel. When in use, the output shaft can be made to rotate or stop by controlling the brake to skid or cut off the braked wheel to achieve the aim of decelerating output or cutting off movement. The utility model skillfully centralizes the functions of a clutch and a speed reducer on one body and has the advantages of simple structure, convenient operation and small size.
Description
The utility model relates to a kind of retarder.
For a long time, people need a kind of retarder with clutch function always.People have done a large amount of work for this reason, but do not obtain ideal results always, and the common practice is that clutch and retarder are combined simply at present.Though do the purpose that also can realize clutch and deceleration like this, its complex structure, bulky, operation inconvenience, cost are higher, especially are not suitable for using and are limiting the occasion of its volume.
The purpose of this utility model is that a kind of planetary reducer with clutch function will be provided, and it can overcome the prior art complex structure, and is bulky, unhandy shortcoming.
The utility model mainly is made of output shaft, input shaft, central gear, planetary pinion, internal gear, Brake drum and break etc., wherein an end of output shaft is a drum, internal gear installs and fixes within it, an input shaft that has central gear links together by bearing and output shaft, planetary pinion is installed on the spoke of Brake drum by it, on input shaft, break is equipped with in the Brake drum outside to Brake drum by Bearing Installation.When break is checked Brake drum, a planetary pinion rotation of not revolving round the sun, and drive internal gear and rotate, motion is by the output shaft output of slowing down.When the releasing of brake Brake drum, Brake drum is not owing to there being external load to dally, and planetary pinion had not only revolved round the sun but also rotation, and then owing to very big the stopping operating of being with work mechanism load, motion is disconnected for internal gear and output shaft.
Input shaft in the utility model can be connected with rolling bearing with output shaft, also can connect with sliding bearing; Central gear can be fastened on the input shaft, for example is connected and fixed with key, also can be that both manufacturing become the gear shaft form.
The utility model rolls into one the function of clutch and retarder dexterously, have simple in structure, reliable performance, easy to operate, the advantage that volume is little.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the sectional drawing according to the planetary clutch retarder that the utility model proposes.
Below concrete structure and the working condition contrast accompanying drawing that the utility model proposes is elaborated.
This planetary clutch retarder comprises output shaft (6), input shaft (9), central gear (8), planetary pinion (5), internal gear (2), Brake drum (11) and break (12) etc.Wherein: the left end of output shaft (6) is a drum, and internal gear (2) installs and fixes within it by screw (1), and the cylinder interior edge face has a bearing hole, and the right-hand member of output shaft (6) is the female splined shaft nested structure.Input shaft (9) becomes the gear shaft structure form with central gear (8) manufacturing, and the right-hand member of input shaft (9) is equipped with needle bearing (7), and input shaft (9) is packed into by this bearing (7) and realized in the bearing hole of output shaft (6) and being connected of output shaft.Brake drum (11) is installed in the left side that input shaft (9) is gone up central gear (8) with bearing (10), on Brake drum (11) spoke three planet pins (3) are installed evenly, be installed on the planet pin (3) with bearing (4) with three planetary pinions (5) of central gear (8) and internal gear (2) engagement, lock formula break (12) is equipped with in the Brake drum outside, and break among the figure (12) is in the position of checking Brake drum.
When wanting output movement, need only move the manipulating handgrip (not drawing among the figure) of break (12), make break (12) check Brake drum (11), at this moment the motion transmitted of input shaft (9) reaches planetary pinion (5) through central gear (8), because Brake drum (11) does not rotate, can only rotation so planetary pinion (5) just can not revolve round the sun, drive internal gear (2) and output shaft (6) simultaneously and rotate, deceleration of motion is exported.
In the time will disconnecting motion, need only move the manipulating handgrip of break (12), make break (12) take-off the brake wheel (11), though at this moment motion still reaches planetary pinion (5) and internal gear (2) by input shaft (9) through central gear (8), but because Brake drum (11) does not have external load, and only overcoming the idle running of surface friction drag, planetary pinion (5) had not only revolved round the sun but also rotation simultaneously.Output shaft (6) then because the institute's work mechanism of be with load is very big, and internal gear (2) and output shaft (6) just stop operating as being fixed, reaches the purpose that disconnection is moved.
Claims (3)
1, a kind of planetary clutch retarder, comprise output shaft (6), input shaft (9), central gear (8), planetary pinion (5), internal gear (2), Brake drum (11) and break (12) etc., it is characterized in that: an end of output shaft (6) is a drum, internal gear (2) installs and fixes within it, an input shaft (9) that has central gear (8) links together by bearing and output shaft (6), planetary pinion (5) is installed on the axle spoke of Brake drum (11) by it, on input shaft (9), break (12) is equipped with in Brake drum (11) outside to Brake drum (11) by Bearing Installation.
2, planetary clutch retarder according to claim 1 is characterized in that output shaft (6) cylinder interior edge face is provided with a bearing hole, and the bearing of installing in the hole can be that rolling bearing also can be a sliding bearing.
3, planetary clutch retarder according to claim 1 is characterized in that central gear (8) is fastened on the input shaft (9) with key.
