Description
Technical field
This utility model be related to that a kind of chain saw with makita 4100NH is engaged without tooth sprocket.
Background technology
Apply for utility model " the supporting guide wheel driver of chain saw being cut with the stone material " patent No. before this utility model people：
ZL2013201708066, the applying date：2013.4.8；The tooth of described driving guide wheel is to engage with the tooth of chain saw, and category slides and grinds
Wipe.During work, the tensile force of chain saw causes the sliding friction point of engagement place to produce high temperature, height plus driving guide wheel to run up
Noise and vibrations.As stone material can not add the tooth of lubricating oil, chain saw and driving guide wheel quickly to wear away in cutting, short life,
The big sheet material of stone material cutting quality, especially cutting granite is affected, affect more very.
Utility model content
The purpose of this utility model, be to provide for that a kind of chain saw with makita 4100NH is engaged without tooth sprocket,
It has the characteristics of be easily worked, especially process super-large diameter without tooth sprocket, escapable cost.And, it is convenient to keep in repair, make
After with certain number, without the screw on tooth sprocket under driving, more renew roller.
One of scheme of the present utility model, a kind of chain saw with makita 4100NH be engaged without tooth sprocket,
It includes sprocket wheel, and the sprocket wheel outer is radially provided with groove, is interval with the grooved position of sprocket wheel and some adapts to oblique cone head
The through hole of screw；One end of the through hole is tooth hole, and the other end of the through hole is bellmouth；In the position of each through hole of groove
Put built-in roller；Described roller is made up of flange bearing, steel bushing, thrust washer, oblique cone head screw；The oblique cone head screw,
Its latter end is provided with thread, and its stage casing is cylindric screw rod, and its first section is oblique cone head；In groove, steel bushing close-fitting is in flange bearing
Outside, thrust washer located at the taper end side of flange bearing, the latter end of oblique cone head screw pass through the bellmouth without tooth sprocket,
Thrust washer, flange bearing, are screwed with the tooth hole without tooth sprocket；The flange bearing and thrust washer and cylindric screw rod are sliding
Match somebody with somebody, freely can rotate.
In order that chain saw easily enters the groove without tooth sprocket, the both sides at the top of groove described in the utility model are provided with
Oblique angle.
It is described in the utility model without tooth sprocket in the first face of first section oblique cone for being provided with oblique cone head screw, if catch.So, may be used
Ensure that oblique cone head screw will not loose or dislocation.It is some in a row side by side without tooth sprocket with catch.
The two of scheme of the present utility model, described roller are made up of flange bearing, thrust washer, oblique cone head screw；Compared with
The first scheme is saved and has abandoned steel bushing.
The beneficial effects of the utility model are, it has high temperature resistant, abrasion performance, a high water proofing property, and the little spy of damping, noise
Point.The oblique cone head screw of high-strength abrasion-proof as the flange bearing in roller is made up of high voltage bearing engineering plastics, is pierced into, is received
When power is rolled, because of two different physical characteristics, different potential differences are produced；In addition, flange bearing is around oblique cone head screw
Cylindric screw rod rotation, belongs to rolling friction at work, when running up, quiet, low friction, low vibrations, high efficiency, and use
Life-span length.More conventional chain saw and sprocket wheel, this utility model are that roller is engaged with chain saw, make cutter head thickness thinner, cutting
Seam is less, especially the big plate of cutting granite, and lumber recovery is high.

Specific embodiment
On a kind of makita 4100NH described in the utility model without tooth sprocket, as shown in figs 1-9, one of scheme：It includes
Sprocket wheel, 1 outer of the sprocket wheel are radially provided with groove 2, are provided with 2 location interval of groove of sprocket wheel and some adapt to oblique cone head screw
Through hole 3；One end of the through hole 3 is tooth hole 4, and the other end of the through hole 3 is bellmouth 5；In each through hole 3 of groove 2
The built-in roller in position 6；Described roller 6 is made up of flange bearing 7, steel bushing 8, thrust washer 9, oblique cone head screw 10；It is described
Oblique cone head screw 10, its latter end are provided with thread 11, and its stage casing is cylindric screw rod 12, and its first section is oblique cone head 13；In groove 2
Interior, outside flange bearing 7, thrust washer 9 is located at the taper end side of flange bearing 7, the latter end of oblique cone head screw for 8 close-fitting of steel bushing
The bellmouth 5 without tooth sprocket, thrust washer 9, flange bearing 7 are passed through, is screwed with the tooth hole 4 without tooth sprocket；The flange
Bearing 7 and thrust washer 9 and cylindric screw rod 12 are slide fits, freely can be rotated.In order that chain saw is easily entered without toothed chain
The groove of wheel, the both sides at the top of groove described in the utility model 2 are provided with oblique angle 14（As shown in Fig. 2,3,4,5）.This utility model
It is described to be provided with 13 one side of first section oblique cone head of oblique cone head screw without tooth sprocket, if catch 15.So, it is ensured that oblique cone head screw
10 will not loose or dislocation, meanwhile, the thickness of the thickness of regulating fender correspondence cutting stone material.It is some with catch 15 without tooth sprocket
Side by side in a row（As shown in Figure 9）.This utility model can be combined with single row or multiple rows, and multiple rows of combination can reach will be waste material disposable
Cut into the efficiency of the big plate of multi-disc.
The two of scheme of the present utility model, described roller are made up of flange bearing, thrust washer, oblique cone head screw；Compared with
The first scheme is saved and has abandoned steel bushing（As shown in Figure 4,5）.It is specific as follows：
A kind of chain saw with makita 4100NH be engaged without tooth sprocket, it includes sprocket wheel, sprocket wheel outer footpath
To groove is provided with, some through holes for adapting to oblique cone head screw are interval with the grooved position of sprocket wheel；One end of the through hole
For tooth hole, the other end of the through hole is bellmouth；In the built-in roller in position of each through hole of groove；Described roller is by method
