Abstract
The utility model relates to an over-driving device for a roller bed. The over-driving device comprises a roller, wherein the roller is fixedly connected with a unidirectional non-return bearing through a key; a shaft head of a roller mounting bearing is connected to the unidirectional non-return bearing through the key; a support bearing and the unidirectional non-return bearing are connected with a belt wheel; a propping thread is arranged on the belt wheel, and the other end of the propping thread props against the key; a first positioning ring and a second positioning ring are connected with the roller mounting bearing. According to the over-driving device, a motor drives a shaft to rotate and simultaneously drives the roller to synchronously rotate through the belt wheel and a belt, when an external-force glass plate slides on the roller, the roller can exceed the original rotating speed to freely rotate forwards at the speed the same as that of the glass plate and cannot be limited by the key, so that the over-rotating is realized, the friction force between the glass plate and the roller is reduced, and the consuming problem of a rubber gasket of the roller is solved; when the use requirements of the device are met, the production cost is lowered, and the labor intensity of operators is reduced; the over-driving device has the characteristics of simple and practical structure and low cost.
Description
Technical field
The utility model relates to solar energy photovoltaic glass manufacturing technology field, and particularly a kind of roller-way surmounts drive unit.
Background technology
The drive unit that roller-way adopts at present generally has three kinds: 1, chain drive structure; 2, vee-belt drives structure; 3, gear drive structure.First kind of way adopts chain that all rollers are connected by sprocket wheel, then drives by motor, thereby realizes the synchronous rotation of all rollers; The second way adopts endless-belt to be connected with the drive shaft at two, by the rotation of belt, then drives and realizes transmission by motor; The third mode adopts the pairing of every roller gear, i.e. 90 ° of pairing spiral wheels, and the rotation of driven by motor axle, thereby the rotation of driven gear, realize the rotation of every roller.1st, 3 kinds of type of drive, due to reliable in structure, can be used usually, but that shortcoming is tooling cost is higher, and the 2nd kind of mode is subject to the restriction of installation site, mounting condition and on-the-spot service condition, sometimes can not reach the effect of anticipation.
In solar energy photovoltaic glass is produced, common type of drive is directly to adopt belt to drive roller turn, thereby reaches the purpose of conveying.This kind of mode is synchronous the rotation, be that sheet glass keeps synchronizeing with the plane speed of roller-way, because common roller and main driving are synchronous rotaries, when forcing to promote when sheet glass moves ahead to produce relative friction, thereby the cushion rubber of roller-way will be crossed out, cause the consumption of roller cushion rubber, the personal services tries hard to recommend into, cost of idleness and easily produces equipment failure.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to propose a kind of roller-way and surmounts drive unit, the mono-directional overrun that can realize roller rotates, solve the consumption problem of roller cushion rubber, when reaching the equipment service requirements, reduce production cost, reduced personnel's labour intensity, there are characteristics simple and practical, with low cost.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of roller-way surmounts drive unit, comprise roller 1, roller 1 is fixedly connected with one-way check bearing 3 by key 5, roller is installed bearing 6 spindle noses and is connected to one-way check bearing 3 by key 5, steady bearing 2, one-way check bearing 3 are connected with belt pulley 8, belt pulley 8 is provided with jackscrew 4, and jackscrew 4 the other ends withstand on key 5, and the first retaining ring 7, the second retaining ring 9 are installed bearing 6 with roller and be connected.
Because the utility model is changed on the basis of original belt pulley, adopt the one-way check bearing, pass through belt pulley, bearing, the combination of key and subsidiary material, rely on belt pulley to carry out transmission, make roller realize surmounting rotation in working direction, be that roller can rotate freely in a direction, other direction cannot rotate, under external force can overspeed rotation, guaranteed with under External Force Acting relative to synchronously rotating, at this moment the front line speed of sheet glass is identical with the plane speed of roller, thereby reduced relative friction forces between the two, the strength that librarian use is very little can allow sheet glass move ahead, reduced the labour intensity of personnel in the time of upper, effectively solved sheet glass in artificial problem of crossing out the roller cushion rubber upper slice the time.The utility model is installed on the transmission roller, overcome prior art middle gear, belt pulley difficult processing, a difficult problem that cost is high, can reach the service requirements of equipment, met need of production, reduce equipment failure rate and maintenance cost, there are characteristics simple and practical, with low cost.
The accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to accompanying drawing, a kind of roller-way surmounts drive unit, comprise roller 1, roller 1 is fixedly connected with one-way check bearing 3 by key 5, roller is installed bearing 6 spindle noses and is connected to one-way check bearing 3 by key 5, steady bearing 2, one-way check bearing 3 is connected with belt pulley 8, belt pulley 8 is provided with jackscrew 4, jackscrew 4 the other ends withstand on key 5, the first retaining ring 7, the second retaining ring 9 is installed bearing 6 with roller and is connected, as adjusting mounting distance, use, the effect that steady bearing 2 plays location and gains in strength, when roller will surmount rotation, bearing 2 plays a supportive role with 3, one-way check bearing.
Principle of work of the present utility model is:
The rotation of driven by motor axle, drive rod 1 by belt pulley 8 and belt synchronously rotates simultaneously, when when the external force sheet glass slides on rod 1, the front line speed of sheet glass surpasses the rotating speed of roller, roller 1 can surmount original rotating speed and rotate forward freely under this external force, reach with the same speed of sheet glass and move ahead, be not subject to the restriction of key 5, thereby realized surmounting rotation, reduce the frictional force between sheet glass and roller, reduced equally personnel's thrust.
