The spinning pulley is characterized in that the pulley further comprises an upper circular ring and a lower circular ring, the inner hole is formed by the upper circular ring and the lower circular ring, and a groove is formed in the end, close to the inner hole, of the spoke. The spinning pulley is overall light, saving in material, low in cost, simple in manufacturing process and suitable for being popularized and applied.
Description
Technical field
The utility model belongs to the metal machining technical field, is specifically related to a kind of endoporus spinning belt pulley of riving.
Background technique
At present in auto industry field, the spinning belt pulley application is more and more extensive, it with traditional casting belt wheel, compare have lightweight, material is economized, manufacturing efficiency is high, beautiful shape, the advantage such as cheap, the water pump pulley of motor car engine, steering pump and fan pulley adopt spinning belt pulley mostly.Engine crankshaft belt pulley is the not fatigue fracture of vibration damping protection bent axle now, mostly is designed to the rubber damping belt pulley, and crankshaft vibration damping belt pulley, because between belt pulley and wheel hub, assembling rubber ring, comes off in order to prevent from being subject to end thrust, at belt pulley design groove.Because of the spinning belt pulley process limitation, can't realize the groove demand, can only adopt casting material or steel pipe to realize the groove demand with casting and cutting technology, these manufacturing process waste raw material, technique is comparatively complicated.
The model utility content
For problems of the prior art, the purpose of this utility model is providing a kind of endoporus spinning belt pulley of riving.
The utility model is realized by the following technical programs:
Described a kind of endoporus spinning belt pulley of riving, comprise gear ring and spoke, the centre of spoke is provided with center hole, be provided with a plurality of V-shaped grooves on gear ring flat circle perisporium, and be respectively equipped with edge and lower edge at the two ends up and down of this V-shaped groove, it is characterized in that this belt pulley also comprises annulus and lower annulus, described upper annulus and lower annulus form endoporus, and described spoke is provided with groove near an end of endoporus.
Described a kind of endoporus spinning belt pulley of riving, is characterized in that described groove is positioned at the spoke centre position.
Described a kind of endoporus spinning belt pulley of riving, is characterized in that described upper annulus arranges with lower annulus is vertical with spoke.
Described a kind of endoporus spinning belt pulley of riving, is characterized in that described groove center and spoke centre are positioned at the same level line.
Described a kind of endoporus spinning belt pulley of riving, is characterized in that described belt pulley adopts steel plate structure, and steel plate thickness is 5-7mm.
A kind of endoporus of the utility model spinning belt pulley of riving compared with prior art, has following beneficial effect:
1. belt pulley intensity is good, and precision is high, and dynamic balance performance is good.
2. belt pulley adopts sheet material forming, and material is economized, and manufacturing procedure is little, and processing cost is low.Originally adopt steel pipe processing, need material 2.86Kg, adopt at present the steel plate spinning only to need 1.57Kg, the operation processing cost has reduced 40%-45%.
3. the steel plate endoporus spinning of riving, realize the spinning structure by the belt pulley that is applied to vibration damping wheel, eliminates the casting and the cutting technology that fall behind, played the effect of energy-saving and emission-reduction.Also can be applied to endoporus has on the transmission pulley of assembling demand, and this endoporus spinning belt pulley of riving is with a wide range of applications.

In figure: 1-spoke, 2-center hole, 3-V shape groove, the upper edge of 4-, edge under 5-, the upper annulus of 6-, annulus under 7-, 8-endoporus, 9-groove.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, and provides embodiment.
As shown in Figure 1, a kind of endoporus of the utility model spinning belt pulley of riving, comprise gear ring and spoke 1, the centre of spoke 1 is provided with center hole 2, be provided with a plurality of V-shaped grooves 3 on gear ring flat circle perisporium, and be respectively equipped with along 4 and lower to 5 at the two ends up and down of this V-shaped groove 3, belt pulley also comprises annulus 6 and lower annulus 7, upper annulus 6 forms endoporus 8 and setting vertical with spoke 1 with lower annulus 7, being specially spoke divides 1 not the same annulus 6 to be connected with the centrum of lower annulus 7, spoke 1 is provided with groove 9 near an end of endoporus 8, this groove 9 is positioned at spoke 1 center portion, be specially groove 9 centers and spoke 1 and be centered close to the same level line.
The rive working process of spinning belt pulley of the utility model endoporus is: 1) cut bar: the steel plate that is 6mm by thickness is cut into the long strip steel plate according to belt pulley stock layout size.2) blanking: the long strip steel plate be cut into is struck out to disk on punch press.3) punching: go out the circular tablet with center hole 2 by the middle of steel plate on punch press, as shown in Fig. 2 structure.4) endoporus is rived: the disk after punching is placed on spinning machine, by spinning tool, center hole 2 place's spokes 1 are rived along center and the plate after riving is drawn into respectively to the circular blank that edge upwarps to both sides, the plate stuck up to upside forms upper annulus 6, the plate stuck up to downside forms lower annulus 7, form endoporus 8 between upper and lower annulus, as shown in Figure 3.5) spinning for the first time: the workpiece of riving is placed on spinning tool, compresses spoke 1 by mould cylindrical is spun into to I-shaped cylinder, as shown in Figure 4.6) spinning for the second time: will be placed on spinning tool through the blank that spinning protects for the first time, cylindrical is spun into to the gear ring with a plurality of V-type grooves 3 shown in Fig. 1, obtain the endoporus spinning belt pulley of riving.
