Abstract
The invention discloses a beat-in device for an engine idle gear shaft. The beat-in device comprises a pressing rod, a protection sleeve and a knocking bolt. An idle gear shaft inserting groove extending in the axial direction is formed in one end of the pressing rod, an opening of the idle gear shaft inserting groove is formed in the end face of one end of the pressing rod, and an axial screw hole is formed in the other end of the pressing rod. The protection sleeve is in a cylinder shape matched with the idle gear shaft inserting groove of the pressing rod. The protection sleeve is made of a nylon material and embedded in the idle gear shaft inserting groove of the pressing rod. The knocking bolt is in screw joint into the axial screw hole of the pressing rod and is locked through a lock nut arranged between the knocking bolt and the pressing rod. According to the beat-in device for the engine idle gear shaft, the assembling efficiency can be greatly improved, and the problems that the idle gear shaft is knocked damaged, installing is not proper and deflection happens during installation can be solved.

It is that air compressor machine can effectively operate, is indispensable parts for diesel engine.But it is lazy
In the cylinder block of gear shaft electromotor to be arranged in respective aperture, because being interference fit with cylinder block,
Idle gear is directly knocked installing hole with hammer by employee, and process of knocking in idle gear shaft to be protected surface can not
Its surface is allowed to produce defects such as scratching, pull.
But idle gear is directly knocked installing hole with hammer by employee, this way not only can strike bad idle gear shaft,
Make its surface produce defects such as scratching, pull, and can cause idle gear shaft that not in place, skew etc. is installed
Problem.
The information being disclosed in this background section is merely intended to increase the reason of the general background to the present invention
Solve, and be not construed as recognizing or imply in any form that this information structure is for this area general technology
Prior art well known to personnel.
Summary of the invention
It is an object of the invention to provide a kind of simple and reasonable electromotor idle gear shaft squeezes into dress
Putting, the fastener driving device of this electromotor idle gear shaft can be greatly improved efficiency of assembling, and it can be avoided that strikes
The problems such as bad idle gear shaft and not in place, the skew of installation.
For achieving the above object, the invention provides the fastener driving device of a kind of electromotor idle gear shaft, this
The fastener driving device of motivation idle gear shaft includes: depression bar, and its one end has axially extended idle gear shaft slot,
The opening of this idle gear shaft slot is opened on one end end face of described depression bar, and the other end of described depression bar is opened
It is provided with axial screw；Protective jacket, it is the cylindrical shape that the idle gear shaft slot with described depression bar is adaptive, should
Protective jacket is nylon material, is embedded in the idle gear shaft slot of described depression bar；And percussion bolt, its
It is screwed in the axial screw of described depression bar, and by being arranged on the lock between described percussion bolt and depression bar
Jack panel is locked.
Preferably, in technique scheme, depression bar is that cylinder is shaft-like.
Preferably, in technique scheme, between locking nut and depression bar, it is additionally provided with spring washer.
Compared with prior art, there is advantages that squeezing into of this electromotor idle gear shaft
Device can be greatly improved efficiency of assembling, and it can be avoided that strike bad idle gear shaft and install not in place, inclined
The problems such as shifting.

Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that this
The protection domain of invention is not limited by detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " bag
Include " or its conversion as " comprising " or " including " etc. will be understood to comprise stated element or
Ingredient, and do not get rid of other element or other ingredient.
As it is shown in figure 1, according to the fastener driving device of the electromotor idle gear shaft of the specific embodiment of the invention
Concrete structure includes: protective jacket 1, depression bar 2, percussion bolt 3 and locking nut 4.Wherein depression bar 2
One end has idle gear shaft slot, and protective jacket 1 is nylon material, is embedded in the idle gear shaft slot of depression bar
In, idle gear shaft to be installed non-press-in section is contained in protective jacket, to be filled by the idle gear shaft section of press-in alignment
The hole entered.Tap bolt 3 and be screwed to the other end of depression bar 2, and by being arranged on percussion bolt 3 and pressure
Locking nut 4 between bar 2 is locked, and taps bolt with iron hammer, it is possible to realize lazy tooth
Wheel shaft is driven in the hole that need to install, and the nylon structure of protective jacket can be effectively protected idler shaft and be subject to crushing；
Frequently use percussion bolt to be tapped and bad can dismantle the percussion bolt renewed, it is possible to be greatly improved assembling effect
Rate, and it can be avoided that strike bad idle gear shaft and the problems such as not in place, skew are installed.
Specifically, as in figure 2 it is shown, depression bar 2 is that cylinder is shaft-like, its one end has axially extended lazy
Gear shaft slot 6, the opening of this idle gear shaft slot is opened on one end end face of depression bar 2, is used for passing through
Protective jacket accommodates idle gear shaft to be installed non-press-in section.The other end of depression bar 2 offers axial screw 7,
For installing percussion bolt 3, tap bolt with iron hammer, it is possible to realize being driven into idle gear shaft needing
