Abstract
The utility model discloses a kind of shaped grooved cast-iron belt pulley, excircle in pulley body has multiple trough of belt successively, have flared or the axle center hole of two ends closing in shape in the axle center of pulley body, the internal diameter size of axle center hole is gradually increased with the girth size of the cylindrical trough of belt of pulley body or reduces.Structure of the present utility model, the gradient on inclined-plane, every layer of grooved bottom both sides is made as 34 degree, 36 degree, 38 degree of three kinds of different models as required；Band groove depth is 1 5mm；The size of axle center hole is gradually increased with the cylindrical size of pulley body, prevents from producing pore in pulley surface and affecting product quality, saves material, reduce manufacturing cost.
Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to a kind of shaped grooved cast-iron belt pulley.
Background technology
Existing cast-iron belt pulley trough of belt is few, and size does not adapt to the requirement of plurality of specifications, poor universality, adds production
Cost；Additionally in casting process, due to the deficiency of structure design, easily form pore, have impact on the quality of product.
Utility model content
The utility model provides a kind of shaped grooved cast-iron belt pulley, solves and there is poor universality in prior art, holds
It is easily formed pore, the problem affecting product quality.
The technical solution of the utility model is, a kind of shaped grooved cast-iron belt pulley, pulley body excircle successively
Having multiple trough of belt, having flared or the axle center hole of two ends closing in shape in the axle center of pulley body, the internal diameter of axle center hole is big
The little girth size with the cylindrical trough of belt of pulley body is gradually increased or reduces.
Shaped grooved cast-iron belt pulley of the present utility model, its feature also includes:
Each described trough of belt depth bounds is 1-5mm, the angle on each inclined-plane, grooved bottom both sides is 34 degree, 36 degree or
38 degree.
The beneficial effects of the utility model are, the gradient on inclined-plane, every layer of grooved bottom both sides be made as required 34 degree,
36 degree, 38 degree of three kinds of different models；Band groove depth is 1-5mm；The size of axle center hole with pulley body cylindrical size by
Cumulative add, prevent from producing pore in pulley surface and affecting product quality, save material, reduce manufacturing cost.
Brief description
Fig. 1 is the structural representation of the utility model embodiment 1 (enlarging shape)；
Fig. 2 is perspective view of the present utility model；
Fig. 3 is the structural representation of the utility model embodiment 2 (two ends closing in shape).
In figure, the 1st, rib edge, the 2nd, trough of belt, the 3rd, axle center hole.
Detailed description of the invention
As shown in Figure 1, Figure 2, Fig. 3, structure of the present utility model is, has flared in the axle center of pulley body or two ends are received
The axle center hole 3 of the degree of lip-rounding, the excircle in pulley body has multiple trough of belt 2 successively, and each trough of belt 2 is according to the need of driving belt
Wanting depth bounds to be 1-5mm, bottom each trough of belt 2, the angle on inclined-plane, both sides is made as 34 degree, 36 degree or 38 degree as required, with
Just the driving belt of general three kind specification is adapted to；The rib of each trough of belt 2 sets along 1 according to the groover rot diameter size correspondence of trough of belt 2
Put, be gradually increased from one end of pulley body to the other end or reduce, not only alleviate total quality, and be easy to check skin
The working order of band.
Existing belt pulley axle center hole is the consistent through hole of diameter, and the axle center hole 3 of the utility model pulley body
Internal diameter size is gradually increased with the girth size of the cylindrical trough of belt of pulley body 2 or reduces, and is i.e. made as thin-wall construction, uses peace
Being connected with self-contained bearing by packing ring during dress, due to significantly reducing of wall thickness, provide significant conservation material, energy resource consumption reduces, fall
The gas hole defect producing in low casting process, it is ensured that product percent of pass.
