Abstract

The utility model discloses a tool for dismantling a gear. The tool for dismantling the gear includes a puller bolt, a draw hook and a puller bracket, wherein the tail part of the puller bolt passes through the center of the puller bracket in a screwed manner; the draw hook passes through the puller bracket; and one end of the draw hook is provided with a stopping head part, and the other end of the draw hook is provided with a hook-shaped part. The tool for dismantling the gear uses the screw structure to dismantle the gear, is simple in structure, enables the dismantling operation of the gear to be labor-saving and high in efficiency, and efficiently lowers the assembly loss.

Description

The instrument of disengage gear

Technical field

The utility model relates to engine art, particularly a kind of instrument of disengage gear.

Background technology

Existing a lot of gears adopt interference fit with cooperating of axle, can well guarantee assembly quality and transmission effect after assembling.But weak point is exactly a misloading or reprocess in actual production to be taken place frequently, and after the misloading or do over again and need dismantle then intractable, gear is difficult to disassemble from axle, and simultaneously, unloading process also causes the damage of gear easily.

The utility model content

The technical problem that the utility model solves provides a kind of instrument of simple in structure, easy to operate, disengage gear that disengage gear efficient is high.

For achieving the above object, the instrument of a kind of disengage gear that the utility model provides comprises: draw a yard bolt, drag hook and draw a yard support; Draw yard bolt to be spirally connected and pass the center of drawing yard support by afterbody; Drag hook passes the said yard support that draws, and an end has the backstop head, and the other end has crook.

Further, draw a yard bolt left end to have the bolt turret head, right-hand member has the taper thimble.

Further, the crook of drag hook is a right angle hook.

Further, drawing yard support is long strip-board shape, and the center offers screwed hole, and the both sides symmetry of screwed hole offers long strip type waist hole.

According to the technical scheme of the utility model, simple in structure because the instrument of this disengage gear utilizes helicitic texture to come disengage gear, make that the disassembling section of gear is laborsaving, efficient is high, effectively reduce the assembling loss.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the instrument of this disengage gear comprises: draw yard bolt 1, drag hook 2 and draw yard support 3.Wherein, draw yard bolt 1 left end head to have bolt turret head (not marking among the figure), the right-hand member afterbody has taper thimble (not marking among the figure), and the middle part has external screw thread; Drag hook 2 is two, comprises respectively: be positioned at middle connecting rod 21 and be positioned at the backstop head 22 of upper end and the right angle hook 23 of lower end, right angle hook 23 extends radially outwardly along connecting rod 21, and upper surface and connecting rod 21 are rectangular; Draw yard support 3 to be long strip-board shape, the center offers screwed hole 31, and the both sides symmetry of screwed hole 31 offers long strip type waist hole 32.

The detailed process of disengage gear is:

To draw yard bolt 1 to be screwed in the screwed hole 31 that draws yard support 3 by the thimble end earlier; Drag hook 2 is penetrated long strip type waist hole 32 by right angle hook 23 ends; And make backstop head 22 prop up the left side of drawing yard support 3; Drag hook 2 can move in long strip type waist hole 32 to the gear of different-diameter, so that better catch on gear face; Then, the thimble that draws yard bolt 1 is propped up axle 5 the end face center that gear 4 is installed, with the urgent bolt turret head that draws yard bolt 1 of air pressure gun, the right side that makes the right angle hook 23 of drag hook 2 collude tight gear 4; Continue urgently, draw yard support 3, move right, and drive drag hook 2 and catch on gear 4 and slowly be pulled out together, break away from axle 5 and accomplish dismounting until gear 4 drawing under the 1 screw thread power effect of yard bolt.

The tool construction of this disengage gear is simple, easy to operate, laborsaving, disengage gear efficient high, effectively reduces the assembling loss.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
