Abstract
The invention discloses a kind of belt pulley, including belt pulley and rotation axis, it is equipped with through-hole among middle belt pulley, for connecting rotation axis, characterized in that the position of the belt pulley and belt contacts is equipped with several dots protrusion and heat emission hole；The rotation axis is equipped with the limiting slot for being parallel to rotation axis axis, and the centre bore of the belt pulley is equipped with the limited block to match with the limiting slot, is fixed limited block on the rotating shaft by fixing piece.Advantage：The belt pulley of the present invention improves the frictional force between belt and belt pulley by the way that dot protrusion is arranged over pulleys carried, since dot is little, frictional force when having no effect on and need the effect buffered by skidding under the state of emergency to not damage belt, while can ensure to work normally；Heat emission hole and reinforcement structure can ensure there are enough rigids while heat dissipation；Accurately belt pulley can be fixed in rotation axis by limited block and limiting slot.
Description
Technical field
The present invention relates to a kind of belt pulleys, belong to technical field of transmission equipment.
Background technology
It is applied to transmission device in many mechanical devices now, and the commonly used belt pulley of transmission device is driven, and is compared
Simplicity is compared compared with gear drive, and belt pulley transmission cost is relatively low, and general belt pulley transmission, by belt pulley, rotation axis, key group
At, belt pulley is iron tyre, among belt pulley there are one and the matched hole of rotation axis, pass through friction between belt and belt pulley
Power is acted, but before belt pulley and belt frictional force not enough or whens excessive velocities is likely to occur slippage problems, and
And will produce heat during quick rotation, belt pulley in the prior art not easy heat radiation, and belt pulley and rotation axis it
Between fixation would generally be uneven and unstable.
Invention content
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, a kind of belt pulley is provided.
In order to solve the above technical problems, the present invention provides a kind of belt pulley, including belt pulley and rotation axis, middle belt pulley
Centre is equipped with through-hole, for connecting rotation axis, characterized in that it is convex that the position of the belt pulley and belt contacts is equipped with several dots
Rise and heat emission hole；The rotation axis is equipped with the limiting slot for being parallel to rotation axis axis, and the centre bore of the belt pulley is equipped with
The limited block to match with the limiting slot is fixed limited block on the rotating shaft by fixing piece.
Further, it is welded with cross reinforcing rib in the heat emission hole.
Further, the limited block is equipped with threaded hole, and the most the inside of the limiting slot is also provided with identical threaded hole,
Limited block is slid into limiting slot, and is fixed limited block on the rotating shaft by bolt and threaded hole, belt pulley fixed position
It is more acurrate.
Further, the belt pulley is equipped with several grooves, constitutes strip structure, is equipped with phase below belt accordingly
Protrusion band with quantity and with the groove match, prominent band is embedded in a groove, can improve frictional force.
Further, the belt pulley uses stainless steel wheel, anti-to get rusty and high intensity.
Further, it need to ensure pulley centers at rotation axis center when the limited block slides into limiting slot innermost end.
The advantageous effect that the present invention is reached：
Compared with prior art, belt pulley of the invention improves belt and belt pulley by the way that dot protrusion is arranged over pulleys carried
Between frictional force have no effect on since dot is little and need the effect buffered by skidding to not damaging under the state of emergency
Bad belt, at the same can ensure normal work when frictional force；Heat emission hole and reinforcement structure can ensure have while heat dissipation
Enough rigids；Accurately belt pulley can be fixed in rotation axis by limited block and limiting slot.

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figs. 1-5, a kind of belt pulley, including belt pulley 1 and rotation axis 2,1 centre of middle belt pulley are equipped with through-hole,
For connecting rotation axis 2, characterized in that the position of the belt pulley 1 and belt contacts is equipped with several dots protrusion 6 and heat dissipation
Hole 7；The rotation axis 2, which is equipped with, is parallel to the limiting slot 3 of rotation axis axis, the centre bore of the belt pulley 1 be equipped with it is described
Limited block 4 is fixed in rotation axis 2 by the limited block 4 that limiting slot 3 matches by fixing piece 8.
In the present embodiment, cross reinforcing rib is welded in the heat emission hole 7.
In the present embodiment, the limited block 4 is equipped with threaded hole 5, and the most the inside of the limiting slot is also provided with identical spiral shell
Limited block 4 is slid into limiting slot 3, and limited block is fixed in rotation axis 3 by bolt and threaded hole, Neng Goubao by pit
It is more acurrate to demonstrate,prove 1 fixed position of belt pulley.
In the present embodiment, the belt pulley 1 is equipped with several grooves 9, constitutes strip structure, is set below belt accordingly
There are identical quantity and the protrusion band with the groove match, prominent band to be embedded in groove 9, frictional force can be improved.
In the present embodiment, the belt pulley 1 uses stainless steel wheel, anti-to get rusty and high intensity.
Pulley centers need to be ensured in rotation axis center in the present embodiment, when the limited block 4 slides into 3 innermost end of limiting slot
Place.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
