Description
Technical field：
This utility model is related to the technical field of crankshaft pulley, more specifically to a kind of knockdown bent axle spinning skin
Belt wheel.
Background technology：
The existing crank pulley being applied to small farm diesel engine of China is generally cast iron materials, and it not only manufactures fiber crops
Tired, and material therefor is many, quality weight, high cost is it is therefore desirable to a kind of structure is simple, easily manufactured, light weight belt pulley
Replaced, thus the spinning belt pulley of spinning steel plate forming arises at the historic moment, existing spinning belt pulley is typically only equipped with one
Individual spinning belt pulley, not only support strength is poor, is also provided only with one V-groove simultaneously, can only coordinate the peace of a driving belt
Dress, the less stable of V belt translation.
Utility model content：
The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of knockdown bent axle spinning skin
Belt wheel, its compact conformation, enhance the support strength of spinning belt pulley, the stability of V belt translation can be effectively improved simultaneously.
Technology solution of the present utility model is as follows：
A kind of knockdown bent axle spinning belt pulley, including belt-pulley hub, outward turning pinch roller and inward turning pinch roller, internal rolling
Belt wheel is made up of inner rim and interior spoke, and outward turning pinch roller is made up of outer spokes and outer rim, and outer rim all becomes with inner rim
Type has V-groove, and the interior spoke of inward turning pinch roller is plugged in outward turning pinch roller, and the outer wall side of inward turning pinch roller lubrication groove spoke is pasted
It is fixed with elastic collar, the outer ring of elastic collar is resisted against on the inwall of the outer rim of outward turning pinch roller；Belt-pulley hub rear side end
The concave station of annular is formed on the outer ring in face, the interior spoke of inward turning pinch roller and the outer spokes of outward turning pinch roller all form method
Lan Bian, the flange of inward turning pinch roller and outward turning pinch roller is installed in the concave station of belt-pulley hub, and several fastening bolts are successively
It is screwed onto on belt-pulley hub through the flange of inward turning pinch roller and the flange of outward turning pinch roller.
Described fastening bolt is evenly distributed on belt-pulley hub around the central axis annular of belt-pulley hub, described fastening spiral shell
Bolt upper sleeve has spring washer, and spring washer is clamped between the head of fastening bolt and the flange of inward turning pinch roller.
The inner rim of described inward turning pinch roller exposes outward turning pinch roller, and the maximum gauge of inner rim is less than the minimum of outer rim
Diameter.
The beneficial effects of the utility model are：
It provides the few crank pulley of a kind of compact conformation, light weight, consumptive material, compares existing spinning belt simultaneously
Wheel, effectively raises the support strength of belt pulley, enhances the stability of belt pulley V belt translation simultaneously.

Specific embodiment：
Embodiment：As shown in Figure 1, a kind of knockdown bent axle spinning belt pulley, including belt-pulley hub 1, outward turning pinch roller 2
With inward turning pinch roller 3, inward turning pinch roller 3 is made up of inner rim 32 and interior spoke 31, and outward turning pinch roller 2 is by outer spokes 21 and foreign steamer
Edge 22 forms, and outer rim 22 and inner rim 32 all form V-groove a, and the interior spoke 31 of inward turning pinch roller 3 is plugged on outside spinning
In belt wheel 2, the outer wall side of spoke 31 in inward turning pinch roller 3 is pasted and is fixed with elastic collar 5, the outer ring of elastic collar 5 against
On the inwall of the outer rim 22 of outer spin pulley 2；The concave station 11 of annular is formed on the outer ring of belt-pulley hub 1 back end surface,
Flange is all formed on the outer spokes 21 of the interior spoke 31 of inward turning pinch roller 3 and outward turning pinch roller 2, inward turning pinch roller 3 is with outward
The flange of spin pulley 2 is installed in the concave station 11 of belt-pulley hub 1, and several fastening bolts 4 sequentially pass through inward turning pinch roller 3
Flange and the flange of outward turning pinch roller 2 be screwed onto on belt-pulley hub 1.
Described fastening bolt 4 is evenly distributed on belt-pulley hub 1 around the central axis annular of belt-pulley hub 1, described tight
Fixing bolt 4 upper sleeve has spring washer, spring washer be clamped in the head of fastening bolt 4 and inward turning pinch roller 3 flange it
Between.
The inner rim 32 of described inward turning pinch roller 3 exposes outward turning pinch roller 2, and the maximum gauge of inner rim 32 is less than outer rim
22 minimum diameter.
Operation principle：This utility model is the belt pulley of bent axle rotary extrusion type spinning, and it, except belt-pulley hub 1, has also mixed two
By the spinning belt pulley (outward turning pinch roller 2 and inward turning pinch roller 3) of steel plate rotary press modelling, inward turning pinch roller 3 coordinates elastic collar 5
The support strength of outward turning pinch roller 2 can be improved；
Inward turning pinch roller 3 and outward turning pinch roller 2 all offer V-groove a simultaneously, then just connect cooperation two root bark band and realize band
Transmission, can effectively improve the stability of V belt translation.
