Abstract
The utility model discloses an equal adjustable belt pulley of race width and quantity, including the cylinder that has the ladder centre bore, the one end of cylinder is equipped with ring shape flange, is equipped with a plurality of radial holes of rectangular shape that distribute along the axial on the outer peripheral face of cylinder, and the spacer sleeve has two at least rings on the outer peripheral face of cylinder, and the inner peripheral surface of every ring is equipped with a plurality of radial screw holes, and every radial screw hole corresponds one the radial hole of rectangular shape, every a bolt is passed in the radial hole of rectangular shape, and a bolt end rotation is in link firmly the ring on the cylinder on the radial screw hole, the side of ring with recess between the corresponding side of ring shape flange forms recess formation pulley grooves between pulley grooves or the corresponding side of adjacent ring. The utility model discloses the accessible changes the quantity and the interval of ring to change the width and the quantity of race, improved the commonality of belt pulley.
Description
Technical field
This utility model relates to a kind of belt pulley, especially relates to a kind of belt grooves width and the most adjustable belt of quantity
Wheel.
Background technology
Existing belt pulley typically produces in cast-in-block mode, and the belt pulley of every kind of model can only corresponding corresponding size
Belt, the quantity of belt grooves is also fixing, so the versatility of existing belt pulley is poor, this just greatly limit belt pulley
Applicable situation, the belt once changed is of different sizes or changes belt quantity, must change whole belt pulley.
Utility model content
Problem to be solved in the utility model is to provide a kind of belt grooves width and the most adjustable belt pulley of quantity, and it can
Adjust width and the quantity of belt grooves, improve the versatility of belt pulley.
The technical solution of the utility model is: a kind of belt grooves width and the most adjustable belt pulley of quantity, including with rank
The cylinder of ladder centre bore, cylindrical one end is provided with annular flange, and cylindrical outer peripheral face is provided with and multiple divides vertically
The strip radial hole of cloth, cylindrical outer peripheral face is jacketed with at least two annulus, and the inner peripheral surface of each annulus is provided with many
Individual radial screw bore, the corresponding described strip radial hole of each radial screw bore, each described strip radial hole passes
A piece bolt, bolt one end is spun in described radial screw bore and annulus is connected on the cylinder；The side of annulus and described circle
Groove type between annular flange flange corresponding side surface becomes groove type between pulley groove or adjacent rings corresponding side surface to become pulley groove.
As improvement, cylindrical ladder centre bore inner peripheral surface is provided with multiple square boss, each described strip footpath
To hole through a described square boss.
As preferred structure, two sides of each annulus are the conical surface, the side of described annular flange correspondence annulus
Also it is the conical surface.
As preferred machine structure, the aperture of cylinder ladder centre bore is provided with keyway.
As improving further, cylinder is provided with lightening hole.
The beneficial effects of the utility model are: have employed multiple annulus and be placed on cylindrical structure, annulus is with cylindrical
Fixed form uses bolt then to lock onto on annulus inner peripheral surface through the strip radial hole on cylinder outer circumference surface
Radial screw bore, thus can change the spacing between the quantity of annulus and annulus according to actual needs, improve belt pulley
Versatility；Further, cylindrical outer circumference surface is provided with detent, and the inner peripheral surface of annulus is provided with positioning convex, and two
Person matches and radial screw bore and the cooperation in the circumferential of strip radial hole can be made more accurate.
Accompanying drawing explanation
Fig. 1 is axonometric chart of the present utility model；
Fig. 2 is three-dimensional exploded view of the present utility model；
Fig. 3 is the A direction view of Fig. 1；

Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to figs. 1 through Fig. 4, a kind of belt grooves width and the most adjustable belt pulley of quantity, including with ladder centre bore
Cylinder 1, one end of cylinder 1 is provided with annular flange 11, and the outer peripheral face of cylinder 1 is provided with two axially distributed length
Bar shaped radial hole 12, the outer peripheral face of cylinder 1 is jacketed with two annulus 2, and the inner peripheral surface of each annulus 2 is provided with two radial directions
Screwed hole 21, the corresponding described strip radial hole 12 of each radial screw bore 21, each described strip radial hole 12 is worn
Crossing a bolt 3, bolt 3 one end is spun in described radial screw bore 21 and annulus 2 is connected on cylinder 1；The side of annulus 2
Groove between pulley groove 4 or adjacent rings 2 corresponding side surface is become with the groove type between described annular flange 11 corresponding side surface
Form pulley groove 4.
The ladder centre bore inner peripheral surface of cylinder 1 is provided with two square boss 13, each described strip radial hole 12
Through a described square boss 13.
Two sides of each annulus 2 are the conical surface, and the side of the corresponding annulus 2 of described annular flange 11 is also the conical surface.
The aperture of cylinder 1 ladder centre bore is provided with keyway 14, and belt pulley connects by the way of key coordinates with keyway 14
It is connected in rotating shaft.
Cylinder 1 is provided with lightening hole 15, can alleviate the weight of whole belt pulley.
In order to enable annulus 2 to be accurately positioned when being placed on cylinder 1, strip radial hole 12 and radial screw bore 21 is made to exist
On Zhou Xiang can accurate match, the outer circumference surface of cylinder 1 is provided with two detents 16, at the inner peripheral surface of annulus 2
Be provided with can be the most chimeric with said two detent 16 two positioning convex 22.
To belt grooves width and the actual requirement of quantity when can use according to belt pulley, adjust the annulus 2 being placed on cylinder 1
Quantity and annulus 2 and annular flange 11, annulus 2 and annulus 2 between distance.
Below being only one preferred embodiment of this utility model, those skilled in the art is equal to by claim work
Change the protection domain both falling within this case.
