Description

A kind of chain saw with makita 4100NH be engaged without tooth sprocket
Technical field
The present invention relates to a kind of chain saw with makita 4100NH be engaged without tooth sprocket.
Background technology
Apply for utility model " cutting the supporting guide wheel driver of chain saw with stone material " patent No. before the present inventor: ZL2013201708066, the applying date:2013.4.8;The described driving tooth of guide wheel is to engage with the tooth of chain saw, and category slides mill Wipe.During work, the tensile force of chain saw runs at high speed plus driving guide wheel, causes the sliding friction point of engagement place to produce high temperature, height Noise and vibrations.Because stone material can not add lubricating oil in cutting, chain saw and the tooth of guide wheel is driven quickly to wear away, short life, The stone material cutting big sheet material of quality, especially cutting granite is influenceed, influence is more very.
The content of the invention
The purpose of the present invention, be to provide for that a kind of chain saw with makita 4100NH is engaged without tooth sprocket, it has The characteristics of being easily worked, especially process super-large diameter without tooth sprocket, escapable cost.Moreover, convenient maintenance, uses one After timing number, without the screw on tooth sprocket under driving, more renew roller.
One of the solution of the present invention, a kind of chain saw with makita 4100NH be engaged without tooth sprocket, it is wrapped Sprocket wheel is included, the sprocket wheel outer is radially provided with groove, be interval with the grooved position of sprocket wheel and some adapt to oblique cone head screw Through hole;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 roller;Described roller is made up of flange bearing, steel bushing, thrust washer, oblique cone head screw;The oblique cone head screw, its end Section 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 outside flange bearing, Thrust washer is located at the taper end side of flange bearing, and the latter end of oblique cone head screw passes through the bellmouth of no tooth sprocket, thrust Packing ring, flange bearing, are screwed with the tooth hole without tooth sprocket;The flange bearing and thrust washer and cylindric screw rod are slide fits, Can freely it rotate.
In order that chain saw is easier the both sides entered at the top of the groove without tooth sprocket, groove of the present invention provided with oblique Angle.
It is of the present invention without tooth sprocket in the first first face of section oblique cone provided with oblique cone head screw, if catch.So, it is ensured 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 the solution of the present invention, described roller is made up of flange bearing, thrust washer, oblique cone head screw;Compared with first The scheme of kind saves and has abandoned steel bushing.
The beneficial effects of the invention are as follows, it has high temperature resistant, abrasion performance, a high water proofing property, and damping, the characteristics of noise is small. Because the flange bearing in roller is made up of high voltage bearing engineering plastics, the oblique cone head screw of high-strength abrasion-proof, stress are pierced into During rolling, because of two different physical characteristics, different potential differences are produced;In addition, circle of the flange bearing around oblique cone head screw Column screw rod rotation, belongs to rolling friction at work, when running at high speed, Jing Yin, low friction, low vibrations, high efficiency, and uses the longevity Life length.More conventional chain saw and sprocket wheel, the present invention is that roller is engaged with chain saw, makes cutter head thickness thinner, and cutting seam is smaller, The especially big plate of cutting granite, lumber recovery is high.

Embodiment
On a kind of makita 4100NH of the present invention without tooth sprocket, as shown in figs 1-9, one of scheme:It includes chain Wheel, the outer of sprocket wheel 1 is radially provided with groove 2, sprocket wheel the location interval of groove 2 provided with some oblique cone head screws that adapt to 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 Roller 6 built in position;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 Conehead screw 10, its latter end is provided with thread 11, and its stage casing is cylindric screw rod 12, and its first section is oblique cone first 13;In groove 2, The close-fitting of steel bushing 8 is located at the taper end side of flange bearing 7 in the outside of flange bearing 7, thrust washer 9, and the latter end of oblique cone head screw is suitable Sequence passes through the bellmouth 5 without tooth sprocket, thrust washer 9, flange bearing 7, is screwed with the tooth hole 4 without tooth sprocket;The flange shaft Hold 7 and thrust washer 9 and cylindric screw rod 12 be slide fit, can freely rotate.In order that chain saw is easier to enter without tooth sprocket Groove, the both sides at the top of groove of the present invention 2 are provided with oblique angle 14(As shown in Fig. 2,3,4,5).It is of the present invention without toothed chain Take turns in first 13 one side of first section oblique cone provided with oblique cone head screw, if catch 15.So, it is ensured that oblique cone head screw 10 will not loosen Come off, meanwhile, the thickness of the thickness correspondence cutting stone material of regulating fender.It is some in a row side by side without tooth sprocket with catch 15 (As shown in Figure 9).The present invention can be combined with single row or multiple rows, and multiple rows of combination can reach that disposable to cut into multi-disc big by famine material The efficiency of plate.
The two of the solution of the present invention, described roller is made up of flange bearing, thrust washer, oblique cone head screw;Compared with first The scheme of kind saves 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 provided with groove, 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 roller built in the position of each through hole of groove;Described roller is by method Blue bearing, thrust washer, oblique cone head screw composition;The oblique cone head screw, its latter end is provided with thread, and its stage casing is cylindric spiral shell Bar, its first section is oblique cone head;In groove, thrust washer is located at the taper end side of flange bearing, and the latter end of oblique cone head screw is suitable Sequence passes through the bellmouth without tooth sprocket, thrust washer, flange bearing, is screwed with the tooth hole without tooth sprocket;The flange bearing and Thrust washer and cylindric screw rod are slide fits, can freely be rotated.
Each roller of the present invention without on tooth sprocket, this roller number is defined as " work roller number ", when without tooth sprocket During rotation, with mutually agreeing with semicircle below every pitch central point of chain saw, " work roller number " drives chain saw operation.This hair Semicircular opening 17 below bright described roller meeting rotation, each pitch central point of chain saw 16 mutually agrees with roller 6, chain The tensile force of saw be close to semicircular opening roller is cylindrical, the operating rate of chain saw is limited by the rotating speed of no tooth sprocket, chain saw It is synchronized with the movement at semicircular opening with being almost without tooth sprocket roller, so contact surface does not produce high temperature, high noisy and vibrations.
Above-described embodiment and schema and non-limiting product form of the invention and style, any art it is common Appropriate change or modification that technical staff is done to it, all should be regarded as not departing from the patent category of the present invention.
