The clutch type worm gear and worm reducer also comprises a push rod, a push block, a first clutch sleeve and a second clutch sleeve; the first clutch sleeve and the second clutch sleeve are matched with each other; the first clutch which sleeves the output shaft is fixedly connected with the worm gear; the second clutch sleeve is connected to the output shaft in a sliding mode through a spline; the push block is flexibly arranged inside axial space of the output shaft in an axial mode; the push block is abut against an inner end of the second clutch sleeve under the push of a tail end of the push rod; an outer end of the second clutch sleeve, which is far from the first clutch sleeve, is provided with a compression spring; the push rod is flexibly arranged inside an inner hole of the output shaft in an axial mode; a head of the push rod is abut against an end cam which is arranged in a rotating mode. The clutch type worm gear and worm reducer which adopts a clutch structure which is simple in structure is simple in operation and stable and reliable in working.
Description
Technical field
The utility model relates to a kind of speed reducer, particularly a kind of clutch type worm-gear speed reducer.
Background technique
Speed reducer, for the transmission device of low rotation speed large torque, reaches motor, internal-combustion engine or other power running up the object of deceleration through the gearing down group between input shaft and output shaft.In a few thing occasion; the working equipment being connected on speed reducer output terminal need to carry out shutdown operation continually; this power source equipment that just requires to be connected on speed reducer input end stops frequently and starts; this not only can bring great induced pressure for power source equipment; shorten its working life, and can cause the waste of resource.Although speed reducer also has few clutch structure that adopted, complex structure, operation inconvenience and work stability and reliability are not high.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of clutch structure that adopts, and clutch structure is simple, the reliable clutch type worm-gear speed reducer of easy and simple to handle and working stability.
For this reason, the utility model is realized in the following way: a kind of clutch type worm-gear speed reducer, comprise deceleration box, input shaft and output shaft, input shaft is vertical with output shaft to be laid, the worm gear that the worm screw that described input shaft is provided with is provided with output shaft engages, it is characterized in that: also comprise push rod, pushing block and first clutch cover of working in coordination and the second clutch cover, described the first clutch cover empty set is fixedly connected with on output shaft and with worm gear, described the second clutch cover is slidably connected on output shaft by spline, axially movable setting in the axial space that described pushing block is provided with at output shaft, pushing block offsets with the inner of the second clutch cover under the impetus of the tail end of push rod, the second clutch cover is provided with Compress Spring away from the outer end of the first clutch cover, described push rod is axially movable setting of endoporus of output shaft, the head end of push rod offsets with the end cam that rotates setting.
In the utility model, the second clutch cover offsets with pushing block all the time under the effect of Compress Spring, when speed reducer need to carry out clutch action, can make push rod generation axial displacement by the rotation of end cam, in the time that push rod moves to the second clutch cover direction, push rod can promote the clutch tooth of the second clutch cover and the clutch tooth of the first clutch cover disengages by pushing block, make input shaft idle running can not drive output shaft to export, in the time that push rod moves to the second clutch cover opposite direction, under Compress Spring effect, the clutch tooth of the second clutch cover contacts with the clutch tooth engagement of the first clutch cover, when being rotated, input shaft can drive output shaft to export.Above-mentioned clutch structure is simple, easy and simple to handle and working stability is reliable.
For make speed reducer " from " or the position of " closing " there is reliable location, the utility model has adopted following technological scheme: described end cam is connected on the inner bar head of motion bar, motion bar rotates setting in the ending cover hole of deceleration box, the outer end bar head of motion bar stretches out that the end cap of deceleration box is outer to be connected with rocking handle; the rocking arm of rocking handle is provided with hinge last; the end cap of deceleration box is provided with positioning pin hole, when hinge last and positioning pin hole are to punctual activity insertion locating stud.Adopt after such scheme, speed reducer " from " or " closing " position, design hinge last aims at and inserts locating stud with positioning pin hole, so just can make clutch position be located reliably.
Accompanying drawing explanation
Fig. 1 be the utility model in " from " structural representation of position;
Fig. 2 is the structural representation of the utility model in " closing " position.
Embodiment
With reference to accompanying drawing, this clutch type worm-gear speed reducer, comprise deceleration box, input shaft 14, output shaft 1, push rod 8, pushing block 4 and first clutch cover 6 of working in coordination and the second clutch cover 5, input shaft 14 laying vertical with output shaft 1, the worm gear 7 that the worm screw 15 that described input shaft 14 is provided with is provided with output shaft 1 engages, described the first clutch cover 6 empty sets are fixedly connected with on output shaft 1 and with worm gear 7, described the second clutch cover 5 is slidably connected on output shaft 1 by spline, interior axial movable setting of axial space 3 that described pushing block 4 is provided with at output shaft 1, pushing block 4 offsets with the inner of the second clutch cover 5 under the impetus of the tail end of push rod 8, the second clutch cover 5 is provided with Compress Spring 2 away from the outer end of the first clutch cover 6, described push rod 8 is axially movable setting of endoporus of output shaft 1, the head end of push rod 8 offsets with the end cam 9 that rotates setting, described end cam 9 is connected on the inner bar head of motion bar 10, motion bar 10 rotates setting in end cap 13 holes of deceleration box, the outer end bar head of motion bar 10 stretches out that the end cap 13 of deceleration box is outer to be connected with rocking handle 12, rocking arm of rocking handle 12 is provided with hinge last, the end cap 13 of deceleration box is provided with positioning pin hole, when hinge last with positioning pin hole to punctual activity insertion locating stud 11.
When speed reducer of the present utility model need to carry out clutch action, first extract locating stud 11, then rotation crank 12, can make push rod 8 that axial displacement occurs by the rotation of end cam 9, in the time that push rod 8 moves to the second clutch cover 5 directions, push rod 8 meetings promote the clutch tooth of the second clutch cover 5 by pushing block 4 and the clutch tooth of the first clutch cover 6 disengages, input shaft 14 is dallied can not drive output shaft 1 to export, in the time that push rod 8 moves to the second clutch cover 5 opposite directions, under Compress Spring 2 effects, the clutch tooth of the second clutch cover 5 and the engagement of the clutch tooth of the first clutch cover 6 contact, when being rotated, input shaft 14 can drive output shaft 1 to export.Completing after clutch operation, locating stud 11 is inserted in hinge last and positioning pin hole again, so rocking handle 12 just can not rotate, so just make clutch position be located reliably.
