Description
Technical field
The present invention relates to a kind of draw-off gear, especially a kind of quick draw-off gear for SEW retarder.
Background technique
The existing puller in workshop is substantially the round shape works such as belt pulley, gear, the bearing brought and dismantled in various mechanical equipments
Part.Rely primarily on pulling claw in their courses of work and catch on demolition part, by rotate freely draw horse central point, can encounter quickly by
Workpiece centre point is drawn, screw rod is then tightened, withstands by drawing workpiece, disassembly slowly.Horse is drawn to be substantially some general parts, for
Seem comparable impracticable to the disassembly of retarder in the existing motor in our workshops and retarder all-in-one machine, in disassembly process,
Since retarder shape is typically all irregular shape, so, retarder can not be dismantled well using above-mentioned puller.
Summary of the invention
To solve the technical problem in above-mentioned background technique, the present invention provides a kind of quick drawings for SEW retarder
Pulling device, the draw-off gear structure is simple, and can effectively improve the removal efficiency of SEW retarder outer end cap, when shortening maintenance
Between.
Specifically, the quick draw-off gear of the present invention for SEW retarder, which is characterized in that include one
Main body and a lead screw offer multiple fastener holes and a centre bore in main body respectively；The centre bore is set to main center
Place, the diameter and lead screw outer diameter in hole are adapted, and hole is provided with internal screw thread, and is adapted in lead screw external screw thread；It is the multiple tight
Solid hole is distributed in centre bore surrounding, opens up the thread circle hole position outside position and retarder end cap and is adapted.Connected with bolt
4 on disk fastener holes are connect and hole that retarder outer end covers, so that main body is fixed on retarder outer end and covers.Center
Hole is connected with screw rod, and screw rod is aligned and withstands retarder axle center, by tightening intermediate screw rod, is carried out drawing to retarder and is torn open
It unloads, to strengthen the fastening effect between draw-off gear and retarder, while will not also generate damage to retarder main body, mention significantly
High maintenance efficiency, ensure that the continuity of production.
In the present embodiment, two U-shaped holes are also provided in main body, described two U-shaped holes are to be oppositely arranged.Work as fastener hole
Position is different or number is less when being unable to satisfy fastening and needing, and carries out spare fastening using U-shaped hole, is applicable in more sizes with this
Retarder, improve the practicability of described device.
In the present embodiment, the diameter of the centre bore is 3cm, and the length of the lead screw is 45cm.

Specific embodiment
With reference to embodiments and technical solution of the present invention is described in detail in respective drawings, so that art technology
The solution of the present invention can be more clearly understood in personnel, but the protection scope being not intended to limit the present invention.
The present invention provides a kind of quick draw-off gears for SEW retarder, and the draw-off gear structure is simple, and can have
Effect ground improves the removal efficiency of SEW retarder outer end cap, shortens maintenance time.
Specifically, the quick draw-off gear of the present invention for SEW retarder, which is characterized in that include one
Main body and a lead screw offer multiple fastener holes and a centre bore in main body respectively；The centre bore is set to main center
Place, the diameter and lead screw outer diameter in hole are adapted, and hole is provided with internal screw thread, and is adapted in lead screw external screw thread；It is the multiple tight
Solid hole is distributed in centre bore surrounding, opens up the thread circle hole position outside position and retarder end cap and is adapted.Connected with bolt
4 on disk fastener holes are connect and hole that retarder outer end covers, so that main body is fixed on retarder outer end and covers.Center
Hole is connected with screw rod, and screw rod is aligned and withstands retarder axle center, by tightening intermediate screw rod, is carried out drawing to retarder and is torn open
It unloads, to strengthen the fastening effect between draw-off gear and retarder, while will not also generate damage to retarder main body, mention significantly
High maintenance efficiency, ensure that the continuity of production.
In the present embodiment, two U-shaped holes are also provided in main body, described two U-shaped holes are to be oppositely arranged.Work as fastener hole
Position is different or number is less when being unable to satisfy fastening and needing, and carries out spare fastening using U-shaped hole, is applicable in more sizes with this
Retarder, improve the practicability of described device.
In the present embodiment, the diameter of the centre bore is 3cm, and the length of the lead screw is 45cm.
The above is only the preferred embodiment of the present invention is described, technical solution of the present invention is not limited to
This, those skilled in the art's made any known deformation on the basis of major technique design of the invention belongs to the present invention
Claimed technology scope, the specific protection scope of the present invention are subject to the record of claims.
