Abstract
The utility model discloses a belt wheel which comprises a wheel seat, wherein the wheel seat is internally provided with an axial hole and a through hole; the rim of the wheel seat is provided with an circular groove; a clamping ring is tightly adhered to the wall of the circular groove and is clamped and sleeved in the circular groove of the wheel seat; and the inner ring surface and the outer ring surface of the clamping ring are respectively subjected to roughening treatment. The belt wheel disclosed by the utility model is simple in structure, and is easy to be realized; the problem of slipping between the belt wheel and a belt is solved effectively, and the stability of the operation for the belt wheel is improved.
Description
Technical field
The utility model relates to the mechanical wheel field, is specially a kind of belt pulley.
Background technique
Belt pulley belongs to dish hub class part, is mainly used in the occasion of remote transmission power, for example the output of miniature diesel mechanomotive force etc.Belt pulley need cooperate belt to use, and carries out transmission through belt in the frictional force of rim of pulley.The phenomenon that the belt pulley of existing technology is prone to and skidding appears in belt influences the belt pulley working stability.
The model utility content
The purpose of the utility model provides a kind of belt pulley, with solve that the existing technology belt pulley is prone to and belt between problem of slip.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of belt pulley includes wheel seat, has axis hole in the middle of the said wheel seat; The hole face is higher than seat surface on the said wheel seat on the said axis hole; And the axis hole two ends are the step-like nose end of hole enlargement, also have a plurality of through holes around said axis hole on the wheel seat, it is characterized in that: said wheel seat wheel rim is provided with circular groove; Said circular groove is a swallow-tail form along wheel seat cross section radially; There is collar to be close in the circular groove that the circular groove cell wall is fastened in wheel seat, said collar cross section and circular groove sectional shape coupling, collar outer ring face, the inner ring face that contacts with the circular groove cell wall are distinguished roughened.
Described a kind of reel is characterized in that: the through hole two ends on the said wheel seat are the step-like nose end of hole enlargement.
The utility model is simple in structure, is easy to realize.The wheel rim place of wheel seat has the circular groove that the cross section is a swallow-tail form; Be with collar in the circular groove; Belt sleeve is on the wheel seat and be stuck on the collar of circular groove; Because collar outer ring face, the inner ring face that contacts with circular groove are distinguished roughened, so have bigger frictional force between collar outer ring face and belt, collar inner ring face and the circular groove, the collar through the equal roughened of inside and outside circle face like this; Solved effectively between belt pulley and the belt and problem of slip occurred, improved the stability of belt pulley work.
