Abstract
The invention discloses a planetary speed reducer capable of disengaging from meshing. The speed reducer comprises a shell and a sun wheel which is arranged in a planetary speed reduction mechanism. The speed reducer is characterized in that the position corresponding to the sun wheel, on the shell is provided with an end cover; the end cover is provided with a plurality of screw thread holes; the shell is correspondingly provided with a plurality of screw thread holes; the end cover and the shell are connected together through the matching of screws and the screw thread holes; the screw thread holes of the end cover is also provided with top threads in a matched mode; and the end cover and the sun wheel are connected together. When a configured motor and a brake are failed, an inner gear of the speed reducer can be disengaged from meshing, after the meshed gear is disengaged from meshing, the speed reducer can rotate under the external force effect, and a host machine which is matched with the speed reducer can transfer the field.
Description
Technical field
The present invention relates to the speed reducer technical field, especially planetary speed reducer.
Background technique
Being applied at present the speed reducer that vehicle track or wheel drive is all the out-of-gear clutch mechanism of gearless, if motor or break break down, speed reducer is inactive, join this speed reducer main frame also can not shift place.
Summary of the invention
The shortcoming existed in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of can out-of-gear planetary speed reducer, it is when motor and break break down, engaging gear breaks away from engagement, facilitates speed reducer to realize under external force rotating the main frame of joining this speed reducer and shifts place.
In order to address the above problem, the present invention is by the following technical solutions: this can out-of-gear planetary speed reducer, comprise housing, be arranged on the sun gear in planetary gear speed reducing mechanism, on housing an arrange end cap corresponding with described sun gear position, this end cap is provided with a plurality of tapped holes, also be correspondingly provided with a plurality of tapped holes on housing, end cap and housing by the cooperating together of screw and tapped hole, coordinate and also are provided with jackscrew with the tapped hole of end cap; End cap and described sun gear link together.
As further technological scheme of the present invention:
In this can out-of-gear planetary speed reducer, on the interior edge face of described end cap, connection one can embed the draw ring of housing, draw ring hollow and one step is set at inner chamber, the draw ring inner chamber clamps a pressure ring and passes through described step to the pressure ring axial limiting, described pressure ring is provided with the axial screw thread through hole, and an attachment screw passes the axial screw thread through hole of pressure ring and is screwed into described sun gear end face.
The invention has the beneficial effects as follows: when joined motor and break break down, the speed reducer internal gear can break away from engagement, and after engaging gear is broken away to engagement, speed reducer can rotate under external force, join this speed reducer main frame can shift place.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is described further:
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is that the embodiment of the present invention breaks away from the engagement schematic diagram,
In figure: 1 sun gear, 2 end caps, 3 draw rings, 4 pressure rings, 5 jackscrews, 6 screws, 7 attachment screws, 8 housings.
Embodiment
As shown in Figure 1, this can mainly comprise housing 8, be arranged on the sun gear 1 in planetary gear speed reducing mechanism by out-of-gear planetary speed reducer, on housing an arrange end cap 2 corresponding with described sun gear 1 position, this end cap 2 is provided with a plurality of tapped holes, also be correspondingly provided with a plurality of tapped holes on housing 8, end cap 2 and housing 8 i.e. cooperating together by screw 6 and tapped hole.Coordinate and also be provided with jackscrew 5 with the tapped hole of end cap 2.
On the interior edge face of described end cap 2, connection one can embed the draw ring 3 of housing 8, draw ring 3 hollows and one step is set at inner chamber, draw ring 3 inner chambers clamp a pressure ring 4 and pass through described step to pressure ring 4 axial limitings, described pressure ring 4 is provided with the axial screw thread through hole, and an attachment screw 7 passes the axial screw thread through hole of pressure ring 4 and is screwed into described sun gear 1 end face.
When the motor of joining when speed reducer and break break down, pull down the screw 6 on end cap 2, jackscrew 5 is screwed in the tapped hole of end cap 2, end cap 2 drives sun gear 1 and moves right together with draw ring 3, pressure ring 4, attachment screw 7, thereby make sun gear 1 break away from engagement, as shown in Figure 2, speed reducer can rotate under external force like this, and it is also removable that main frame is joined by institute.
