One through hole, the second through hole, the axis of third through-hole and fourth hole on same straight line, the first through hole, the second through hole,
Third through-hole and fourth hole are interconnected.
Preferably, the first through hole and third through-hole are arranged to truncated cone-shaped structure, the first through hole and third through-hole
The small area end of truncated cone-shaped structure connected respectively with the second through hole, the truncated cone-shaped structure of the first through hole and third through-hole
The area at small area end is identical, and the first through hole is identical with the area at the large area end of the truncated cone-shaped structure of third through-hole.
Preferably, four fifth holes are uniformly provided with the circular trough, the fifth hole connects with fourth hole, institute
State the axis of fifth hole and the diameter parallel of first through hole.
Preferably, the edge of second pulley body is processed as arc.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model is reasonable in design, circular trough and fifth hole design in the second pulley body, can
Make dismounting and installation more convenient, while the design of fourth hole, can substantially reduce the quality of belt pulley.
Brief description of the drawings
Fig. 1 is a kind of structural representation of belt sheave of the utility model；
Fig. 2 is a kind of side view of belt sheave of the utility model.
In figure：The pulley bodies of 1- first, the pulley bodies of 2- second, 3- circular troughs, 4- first through hole, 5- second are logical
Hole, 6- third through-holes, 7- fourth holes, 8- fifth holes.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, primary territory those of ordinary skill is not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of belt sheave, including the first belt pulley
The pulley body 2 of main body 1 and second, the pulley body 2 of the first pulley body 1 and second are formed in one structure, institute
State the first pulley body 1 and the second pulley body 2 is arranged to cylindrical structural, and the cylinder knot of the first pulley body 1
The sectional area of structure is less than the sectional area of the cylindrical structural of the second pulley body 2, and first pulley body 1 is arranged on second
The middle side part of pulley body 2 one, first pulley body 1 are provided with first through hole 4, first pulley body 1 with
The junction of second pulley body 2 is provided with the second through hole 5, and second pulley body 2 is provided with third through-hole 6 and the 4th
Through hole 7, the first through hole 4, the second through hole 5, the axis of third through-hole 6 and fourth hole 7 are on same straight line, and described
One through hole 4, the second through hole 5, third through-hole 6 and fourth hole 7 are interconnected, and the first through hole 4 and third through-hole 6 are set
For truncated cone-shaped structure, the small area end of the truncated cone-shaped structure of the first through hole 4 and third through-hole 6 connects with the second through hole 5 respectively
Logical, the first through hole 4 is identical with the area at the small area end of the truncated cone-shaped structure of third through-hole 6, the first through hole 4 and the
The area at the large area end of the truncated cone-shaped structure of three through holes 6 is identical, in second pulley body 1 with the first pulley body
