Abstract
The utility model discloses a spinning pulley made of shell metal. The spinning pulley made of the shell metal aims at solving the problem that because the joint between a tooth surface and a spoke of an existing spinning pulley made of the sheet metal is in a folded mode, material consumption is high, and production cost is increased. According to the spinning pulley made of the shell metal, a wheel rim (1) is smoothly connected with a spoke (4) through a curved surface, the axial section of a whole formed by the wheel rim (1), the spoke (4), a bearing pedestal (3) and a check ring (2) is arranged to be in an S shape, one end of the bearing pedestal (3) is connected with the lower end of the spoke (4) and arranged in the wheel rim (1), and the upper end of the check ring (2) is connected with the other end of the bearing pedestal (3). Therefore, the spinning pulley made of the shell metal has the advantages that materials are saved, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of belt pulley, especially relates to a kind of sheet metal made spinning belt pulley be comprised of wheel rim, spoke and bearing support.
Background technique
At present, a kind of so collapsible spinning Vee pulley V is disclosed on market, its structural feature is: the flank of tooth, spoke and axle sleeve, consist of, axle sleeve one end is connected with spoke is vertical, and be placed in the central position of spoke, described spoke outer is connected with the flank of tooth one end, makes spoke, axle sleeve and the flank of tooth form axial cross section and is the U shape, and clutch can be arranged in the cavity formed by spoke, the flank of tooth and axle sleeve.But, because the joint of the flank of tooth and spoke is collapsible, cause materials consumption larger, increased cost of production.
Summary of the invention
The purpose of this utility model is to provide a kind of material of both having saved, the sheet metal made spinning belt pulley that can reduce production costs again.
For achieving the above object, a kind of sheet metal made spinning belt pulley of the utility model, by wheel rim, spoke and bearing support, formed, wheel rim and spoke form axial cross section and are cantilever-shaped, described wheel rim by curved surface together with the spoke smooth connection, described wheel rim, spoke and bearing support and back-up ring are arranged to axial cross section and are the S shape, make bearing support one end be connected with the spoke lower end and be placed in wheel rim, the back-up ring upper end is connected with the bearing support the other end.
Described back-up ring exterior edge face is vertical with the wheel coil axis.
Described bearing support center line and wheel rim axis coaxle.
Described spoke exterior edge face is perpendicular to the wheel coil axis.
A kind of sheet metal made spinning belt pulley, by wheel rim, spoke and bearing support, formed, wheel rim and spoke form axial cross section and are cantilever-shaped, described wheel rim, spoke and bearing support are arranged to axial cross section and are the U shape, make bearing support one end be connected and be placed in wheel rim with the spoke lower end.
It is tilting that described spoke and wheel coil axis are predetermined angular, is symmetrically arranged with at least two pilot holes on described spoke.
After adopting this structure, due to described wheel rim by curved surface together with the spoke smooth connection, described wheel rim, spoke and bearing support and back-up ring are arranged to axial cross section and are the S shape, make again bearing support one end be connected with the spoke lower end and be placed in wheel rim, the back-up ring upper end is connected with the bearing support the other end.Both save material thereby reach, the purpose that can reduce production costs again.
the accompanying drawing explanationbelow in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the main cross-sectional schematic of a kind of sheet metal made spinning belt pulley of the utility model.
Accompanying drawing 2 is main cross-sectional schematic of the another kind of mode of execution of a kind of sheet metal made spinning belt pulley of the utility model.
In figure: 1. wheel rim 2. back-up ring 3. bearing support 4. spokes.
embodimenta kind of sheet metal made spinning belt pulley of the utility model shown in accompanying drawing 1, by wheel rim 1, spoke 4 and bearing support 3, formed, wheel rim 1 forms axial cross section with spoke 4 and is cantilever-shaped, described wheel rim 1 by curved surface together with spoke 4 smooth connections, described wheel rim 1, spoke 4 are arranged to axial cross section with bearing support 3 and back-up ring 2 and are the S shape, make bearing support 3 one ends be connected with spoke 4 lower ends and be placed in wheel rim 1, back-up ring 2 upper ends are connected with bearing support 3 the other ends; Described back-up ring 2 exterior edge faces are vertical with wheel rim 1 axis; Described bearing support 3 center lines and wheel rim 1 axis coaxle; Described spoke 4 exterior edge faces are perpendicular to wheel rim 1 axis; A kind of sheet metal made spinning belt pulley shown in accompanying drawing 2, by wheel rim 1, spoke 4 and bearing support 3, formed, wheel rim 1 forms axial cross section with spoke 4 and is cantilever-shaped, described wheel rim 1, spoke 4 are arranged to axial cross section with bearing support 3 and are the U shape, make bearing support 3 one ends be connected with spoke 4 lower ends and be placed in wheel rim 1; It is tilting that described spoke 4 and wheel rim 1 axis are predetermined angular, on described spoke 4, is symmetrically arranged with at least two pilot holes.
