Abstract
The utility model discloses a wheel puller of a low-power transmission wheel train. The wheel puller comprises a supporting plate, wherein a nut is arranged in the middle of the supporting plate and connected with a bolt in a matched manner; working arms are arranged at positions on the supporting plate, which are close to the ends; the working arms and the supporting plate form a rectangular framework with an opening; the axis of the nut penetrates through a middle line of the opening; one end of the bolt, which extends out of the supporting plate, is connected with an operation rod sleeve; the other end of the bolt is connected with a working top and inserted into the rectangular framework; the working arms are symmetrically distributed along the axis of the nut and are in horizontal L shapes; the inner sides of the openings of the working arms are straight edges; and chamfers or arcs are formed on the outer sides of the working arms. With the adoption of the wheel puller, the problem of limitation of the space of a transmission wheel to the construction space of the wheel puller is effectively solved; and wheel trains can be quickly and economically replaced.
Description
Technical field
The utility model relates to a kind of maintenance tool, specifically, relates to a kind of small-power train pulley extractor.
Background technology
Small-power drive system is low because of its transmission power; So its interference fit with wheel is little usually when conventional design; But its project organization is compact especially, and this structural design mode is just but brought certain difficulty to the repair and maintenance of equipment; Spatial design is narrow and small owing to be associated between the mechanism, many times in the demolishing process of equipment, needs by special tool(s).
Instrument commonly used now has the Three-claw pull-horse pulley extractor, and the Three-claw pull-horse pulley extractor surpasses pinch roller remaining space of living in because of its three-jaw requisite space, and is high to the transformation complicacy and the required precision of Three-claw pull-horse pulley extractor, so its use is uncommon.Now, operation site is badly in need of wanting a kind of economy, the instrument of dismounting train easy to use.
The utility model content
To above-mentioned deficiency of the prior art, the utility model provides the small-power train pulley extractor of train dismounting in the completion confined space a kind of simple in structure, quicker, economic.
The technical scheme that the utility model is taked is:
A kind of small-power train pulley extractor comprises gripper shoe, and said gripper shoe middle part is provided with nut, and nut and bolt are connected; Said gripper shoe is provided with working arm near the place, end; Said working arm and gripper shoe are formed the rectangular frame with opening; Said nut axis passes the center line of said opening; The end that said bolt stretches out gripper shoe is connected with the action bars sleeve, and the bolt other end is connected with the work top and inserts in the rectangular frame.
The end face of said work top is a taper seat.
Said working arm is symmetrically distributed along the nut axis, is traverse " L " shape.
Said working arm opening inboard is a straight flange, and arranged outside has chamfering or circular arc.
The beneficial effect of the relative prior art of the utility model:
The utility model small-power train pulley extractor has solved the restriction of drive space to the pulley extractor construction space effectively, the replacing of faster, more economical completion train.

The specific embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment:
Accompanying drawing 1-2 can know that a kind of small-power train pulley extractor comprises gripper shoe 5, and said gripper shoe 5 middle parts are provided with nut 4, and nut 4 is connected with bolt 3; Said gripper shoe 5 is provided with working arm 7 near the place, end; Said working arm 7 is formed the rectangular frame with opening with gripper shoe 5; Said nut 4 axis pass the center line of said opening; The end that said bolt 3 stretches out gripper shoe 5 is connected with action bars sleeve 2, and bolt 3 other ends are connected with work top 6 and insert in the rectangular frame; The end face of said work top 6 is a taper seat; Said working arm 7 is symmetrically distributed along nut 4 axis, is traverse " L " shape; Said working arm 7 openings inboard is a straight flange, and arranged outside has chamfering or circular arc.
The utility model small-power train pulley extractor has utilized the operation principle of leading screw-screw transmission; The special construction that welding and drive match on screw; Transmission through leading screw-screw is used the masterpiece of its generation on the magnitude of interference of train and power transmission shaft, thereby drive is pulled up from power transmission shaft.The special construction that welds on the screw; Its two working arm becomes 180 ° of layouts; When leading screw-screw transmission; The power of its generation affacts on the drive through two working arms, and the size of power can overcome the power that interference between drive and the power transmission shaft produces fully, and the direction of power and its active force are on the contrary and do not have a radial component.The structure of two working arms is made according to train spatial placement situation, makes it satisfy in the replacing process demand to the space fully.
The utility model small-power train pulley extractor method for using is following: the workload of pulley extractor 8 is transferred to a certain degree; Then its working arm 7 is placed into the back of drive 9; The amount of adjustment bolt 3; It is applied on certain power to the power transmission shaft 10, and with action bars 1 bolt 3 of screwing, the displacement that then produces between bolt 3 and the nut 4 will change into the displacement between drive 9 and the power transmission shaft 10.Then drive 9 is pulled up from power transmission shaft 10.
The utility model small-power train pulley extractor has solved the restriction of drive space to the pulley extractor construction space effectively, the replacing of faster, more economical completion train.
