Abstract
The invention discloses a spinning belt pulley structure. Circular reinforcing pads are fixedly connected to two sides of the belt pulley. The spinning belt pulley structure not only can keep the original advantages of the spinning belt pulley, but also can break through the 300 mm limitation without tearing, so that the need for transmitting high moment of force is satisfied.
Description
Technical field
The present invention relates to the engine mechanical technical field, relate to a kind of spinning belt pulley structure in particular.
Background technique
Automotive dead weight alleviates 10%, and its fuel efficiency can improve 15%, and fuel efficiency improves, and means fuel consumption and blowdown two reductions of automobile.Therefore, alleviating automotive dead weight, is to improve vehicle energy saving and the most effective way of the feature of environmental protection.Motor is as the big assembly of automobile most critical, and the weight that alleviates motor is most important to reducing automotive dead weight.
Belt pulley is to belong to dish hub class part, and general relative size is bigger, on the manufacturing process generally based on casting, forge.The design that stock size the is bigger method of casting, material generally all is cast iron, shortcoming is that weight is big.Fall under the heavy trend at motor, introduce external new technology, take spinning process for the belt pulley that diameter simple in structure is little, the weight of belt pulley can be reduced more than 50% like this, cost also reduces greatly.
But because present condition restriction, the diameter of spinning belt pulley can't be done greatly, the shortcoming of spinning process be exactly the thickness of the steel plate of spinning can only be 2-3mm, in case the diameter of belt pulley is excessive, corresponding carry-over moment also can increase, easily belt pulley is torn, also do not had diameter to surpass the spinning belt pulley of 300mm in the market.
Summary of the invention
The invention provides a kind of spinning belt pulley structure, can make spinning belt pulley under the prerequisite that keeps existing advantage, diameter is broken through the restriction of 300mm, and can not tear, and can satisfy the demand of transmitting big moment.
The present invention adopts following technological scheme to realize above-mentioned purpose: a kind of spinning belt pulley structure, it is characterized in that, and be fixedly connected with the reinforcement backing plate of annular in these belt pulley both sides.
As further specifying of such scheme:
Preferably, backing plate and outer backing plate in described reinforcement backing plate includes, this interior backing plate and outer backing plate are the annular plate-like structure with the belt pulley corresponding matching.
Preferably, described reinforcement backing weld is connected on the belt pulley both sides.
Preferably, described reinforcement backing plate is connected the belt pulley both sides by rivet or bolt.
Preferably, described reinforcement backing plate is provided with and strengthens the radially stiffening rib of ability to bear.
Preferably, the strip projected parts structure of described stiffening rib for radially arranging along the reinforcement backing plate.
The beneficial effect that the present invention adopts above technological scheme to reach is: spinning belt pulley structure of the present invention is because being provided with the reinforcement backing plate that strengthens lear energy, the diameter that therefore can guarantee spinning belt pulley still can satisfy work requirements during greater than 300mm, and still has advantages such as in light weight, that cost is low, stock utilization is high, balance is good.
Description of drawings

Fig. 2 is the sectional view of spinning belt pulley structure of the present invention.
Description of reference numerals:
Backing plate in the 1-, 2-belt pulley, the outer backing plate of 3-, 4-rivet.
Embodiment
For further setting forth 26S Proteasome Structure and Function of the present invention, below in conjunction with accompanying drawing and preferred embodiment the present invention is elaborated, but be to be understood that protection scope of the present invention is not subjected to the restriction of embodiment.
Fig. 1 is the schematic representation of the described spinning belt pulley structure of present embodiment, Fig. 2 is the cross-sectional schematic of the described spinning belt pulley structure of present embodiment, as shown in FIG., the shelly main body that this spinning belt pulley structure is as a whole, by rivet 4 riveted joints annular reinforcement backing plate is arranged at belt pulley 2 internal surfaces and outer surface, the reinforcement backing plate that is riveted on belt pulley 2 internal surfaces is interior backing plate 1, the reinforcement backing plate that is riveted on belt pulley 2 outer surfaces is outer backing plate 3, and this interior backing plate 1 and outer backing plate 3 are the annular plate-like structure with belt pulley 2 corresponding matching.
In the present embodiment, because belt pulley 2 inside and outside both sides all are provided with the reinforcement backing plate, strengthened the lear energy of belt pulley 2, therefore, as long as backing plate intensity is enough, the diameter of spinning belt pulley just can be broken through the restriction of 300mm, and this spinning belt pulley structure still has plurality of advantages such as the conventional spinning belt pulley is in light weight, cost is low, stock utilization is high, balance is good.
In other embodiments, strengthen backing plate and can also be welding or bolt connection with being connected of belt pulley 2, on the reinforcement backing plate, can also arrange and strengthen the radially stiffening rib of ability to bear, these stiffening ribs can be along strengthening the strip projected parts structure that backing plate radially arranges, and also can be the protruding structures of concentric annular.
Only for one of preferred embodiment of the present invention, can not limit to the present invention with this shown in the above embodiment of the present invention and the accompanying drawing, under the condition that does not break away from marrow of the present invention, any change that those skilled in the art do all belongs to protection scope of the present invention.
