Abstract
A planetary speed reducer capable of disengaged operation includes a housing and a sun wheel arranged in the planetary speed reducing mechanism, and is characterized in that an end cover corresponding to the sun wheel in position is arranged on the housing; a plurality of threaded holes are arranged on the end cover, and a plurality of threaded holes are correspondingly arranged on the housing; the end cover is matched and connected with the housing through screws and the threaded holes; jack screws are matched with the threaded holes of the end cover; and the end cover is connected with the sun wheel. When the equipped motor and brake fail, the gear in the speed reducer can be disengaged, so as to enable the speed reducer to rotate under external force after the meshed gear is disengaged, as a result, the main machine equipped with the speed reducer can move to an another site.
Description
Technical field
The utility model relates to speed reducer technical field, especially planetary speed reducer.
Background technique
The speed reducer that is applied to vehicle track or wheel drive at present all is the out-of-gear clutch mechanism of gearless, if motor or break break down, then speed reducer is inactive, join this speed reducer main frame also can not shift the place.
The model utility content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model be 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, makes things convenient for speed reducer to realize rotating the main frame of promptly joining this speed reducer under external force and shifts the place.
In order to address the above problem, the utility model is by the following technical solutions: this can out-of-gear planetary speed reducer, comprise housing, be arranged on the sun gear in the planetary gear speed reducing mechanism, the corresponding end cap that on housing, is provided 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 the housing, end cap and housing promptly by the cooperating together of screw and tapped hole, cooperate with the tapped hole of end cap also to be provided with jackscrew; End cap and described sun gear link together.
As further technological scheme of the present utility model:
In this can out-of-gear planetary speed reducer, connection one can embed the draw ring of housing on the interior edge face of described end cap, 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 beneficial effects of the utility model are: when the motor of being joined and break broke down, the speed reducer internal gear can break away from engagement, engaging gear is broken away from engagement after, speed reducer can rotate under external force, join this speed reducer main frame can shift the place.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is that the utility model embodiment breaks away from the engagement schematic representation,
Among the 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 the planetary gear speed reducing mechanism by out-of-gear planetary speed reducer, the corresponding end cap 2 that on housing, is provided 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 the housing 8, end cap 2 and housing 8 i.e. cooperating together by screw 6 and tapped hole.Cooperate with the tapped hole of end cap 2 and also to be provided with jackscrew 5.
Connection one can embed the draw ring 3 of housing 8 on the interior edge face of described end cap 2, 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 motor of joining when speed reducer and break break down, pull down the screw 6 on the 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.
Claims (2)
1. can out-of-gear planetary speed reducer, comprise housing, be arranged on the sun gear in the planetary gear speed reducing mechanism, it is characterized in that: the corresponding end cap that on housing, is provided 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 the housing, end cap and housing promptly by the cooperating together of screw and tapped hole, cooperate with the tapped hole of end cap also to be provided with jackscrew; End cap and described sun gear link together.
2. according to claim 1 can out-of-gear planetary speed reducer, it is characterized in that: connection one can embed the draw ring of housing on the interior edge face of described end cap, 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.
