Abstract
The utility model discloses a kind of gear hobbing on roller picker, comprise the gear hobbing body 1 that can be connected on roller bearing and the tooth head 2 be distributed on gear hobbing body 1, extend to form continuous print taper dignity 3 toward the tooth root direction of tooth head 2 respectively from the tooth top both sides of tooth head 2.When this gear hobbing is used on roller picker, owing to devising taper dignity 3, it is no longer rectangular-shaped for forming sieve aperture between gear hobbing, the dead angle that blocking easily occurs no longer is there is in the tooth root direction of tooth head, thus the sieve aperture no longer blockage phenomenon that this gear hobbing is formed, substantially increase screen rate and make screening more even, also can meet the screening of humidity compared with gathering coal simultaneously, substantially increase the versatility of this gear hobbing; Owing to devising the continuous print taper dignity from tooth head to tooth root, gear hobbing thickness is thickening gradually to tooth root direction from tooth top, strengthens the intensity of tooth root position, therefore in screening process, no longer easily broken teeth phenomenon occurs, ensure that working continuously of roller picker, improve the screening effeciency of roller picker.
Description
Technical field
The utility model relates to coal mine equipment field, specifically a kind of gear hobbing on roller picker.
Background technology
Colliery roller picker is that the axis of rolling horizontally set in a row with multiple gear hobbing is formed rolling compass screen surface and the device rotated by chain-driving roller bearing, gear hobbing on the axis of rolling is arranged by separation sleeve interval, the coal particles of different size is sent to the front end of the drum screen of rotation, tiny coal particles is by forming falling of sieve aperture between the axis of rolling on rolling compass screen surface or between two gear hobbings, remaining bulk particle will by rotate gear hobbing or separation sleeve by pull over to drum screen end thus leave rolling compass screen surface, gear hobbing great majority on current roller picker are plum blossom-shaped and parabolic shape, gear hobbing is crisscross arranged on two parallel rollers, the sieve aperture that the gear hobbing of these two kinds of shapes is formed is all rectangular-shaped (seeing roller bearing compass screen surface from top to bottom), the sieve aperture of this shape is in long-term screening process, easily form coal slime in the right angle of rectangular-shaped sieve aperture to pile up, if continue to use, especially for constantly sticking in right angle with humidity compared with the coal slime on gathering coal thus causing slot size inconsistent and the final clogging that sieve aperture occurs, thus cause screening inequality and reduce screen rate, the tooth root portion intensity of existing gear hobbing is simultaneously low, and in the process used, easily broken teeth phenomenon occurs, Renewal process is wasted time and energy.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of gear hobbing on roller picker, formation sieve aperture between gear hobbing is no longer rectangular-shaped, eliminate the dead angle that blocking easily occurs, this gear hobbing rational in infrastructure and be easy to realize, sieve aperture is blockage phenomenon no longer, substantially increases screen rate, sieves more even simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: comprise the gear hobbing body that can be connected on roller bearing and the tooth head be distributed on gear hobbing body, extends to form continuous print taper dignity from the tooth top both sides of tooth head respectively toward the tooth root direction of tooth head.
When this gear hobbing is used on roller picker, owing to devising taper dignity, it is no longer rectangular-shaped for forming sieve aperture between gear hobbing, the dead angle that blocking easily occurs no longer is there is in the tooth root direction of tooth head, thus the sieve aperture no longer blockage phenomenon that this gear hobbing is formed, substantially increase screen rate and make screening more even, also can meet the screening of humidity compared with gathering coal simultaneously, substantially increase the versatility of this gear hobbing; Owing to devising the continuous print taper dignity from tooth head to tooth root, gear hobbing thickness is thickening gradually to tooth root direction from tooth top, strengthens the intensity of tooth root position, therefore in screening process, no longer easily broken teeth phenomenon occurs, ensure that working continuously of roller picker, improve the screening effeciency of roller picker.
The utility model devises, and is disposed on roller bearing by described gear hobbing by separation sleeve, is be arranged in parallel by the roller bearing of at least two covers with this gear hobbing, and the gear hobbing on adjacent two cover roller bearings is crisscross arranged, and forms V-type sieve aperture between the taper dignity of gear hobbing.

Fig. 2 is front view of the present utility model;
Fig. 3 is left view of the present utility model;
Fig. 4 is top view of the present utility model;
Fig. 5 is the roller bearing with this gear hobbing.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be a specific embodiment of the present utility model as Figure 1-5, this gear hobbing on roller picker, comprise the gear hobbing body 1 that can be connected on roller bearing and the tooth head 2 be distributed on gear hobbing body 1, extend to form continuous print taper dignity 3 toward the tooth root direction of tooth head 2 respectively from the tooth top both sides of tooth head 2.
In this example, be disposed on roller bearing 5 by described gear hobbing by separation sleeve 4, be arranged in parallel by the roller bearing 5 of two covers with this gear hobbing, the gear hobbing on adjacent two cover roller bearings 5 is crisscross arranged, and forms V-type sieve aperture 6 between the taper dignity 3 of gear hobbing.
According to screening requirement, the above-mentioned roller bearing with this gear hobbing can be arranged in parallel is 3 covers, 4 covers, 5 covers or more cover, and the more screenings of tricks of setting are more even.
Technique effect of the present utility model is:
1. owing to devising taper dignity 3, it is no longer rectangular-shaped for forming sieve aperture between gear hobbing, the dead angle that blocking easily occurs no longer is there is in the tooth root direction of tooth head, thus the sieve aperture no longer blockage phenomenon that this gear hobbing is formed, substantially increase screen rate and make screening more even, also can meet the screening of humidity compared with gathering coal simultaneously, substantially increase the versatility of this gear hobbing.
2. owing to devising taper dignity 3, thickeied the thickness near gear hobbing tooth root, improve the intensity at tooth root position, no longer easily there is broken teeth phenomenon in gear hobbing in screening process, no longer because broken teeth phenomenon changes gear hobbing, improves the continuity of screening process.
3. due to devise gear hobbing taper dignity 3 between form V-type sieve aperture 6, add and fall into coal cinder in V-type sieve aperture to the friction of taper dignity, thus coal cinder can be allowed constantly to take away the coal slime sticked in taper dignity, the roller picker making to have V-type sieve aperture 6 with self-cleaning function, thus the sieve aperture of removing blocking that need not be artificial, substantially increase screening efficiency.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
