Abstract
The utility model discloses a combined rotary-press belt pulley comprising a belt pulley groove of a main-bearing driving part and a belt pulley groove of a driving part, wherein the belt pulley groove of the main-bearing driving part is provided with a drive shaft mating hole and a flange spigot and is in a cast structure, the belt pulley grove of the driving part is not provided with a drive shaft mating hole and is in a rotary press structure, a flange plane of the belt pulley groove of the main-bearing driving part is matched with an inner hole and an end surface of the belt pulley groove of the driving part to limit a position, and the belt pulley grove of the main-bearing driving part is tightly connected with the belt pulley groove of the driving part. The combined rotary-press pulley is assembled in a split mode, combines rotary casting, reduces weight in a rotary press mode, strengthens casting, can be simply disassembled, is convenient to assemble and integrates the advantages of rotary-press pieces and iron casting pieces. The utility model has the advantages of light weight, aesthetic appearance, low rotary inertia, high production efficiency, simple structure, reliable connection, good integral manufacturing technology, can prolong the service life of a cooling water pump, and can increase power performance and reduce oil consumption and discharge for a whole vehicle.
Description
Technical field
The utility model belongs to the motor vehicle transmission field of mechanical technique, relates to a kind of spinning belt pulley, and particularly a kind of combined type spinning belt pulley especially is useful on the auto pump and uses.
Background technique
Known many wedges mlultiple-groove sheave mostly is the foundry goods belt pulley, weight and rotary inertia are very big, existing foundry goods belt pulley is applied on the auto pump, because many wedges mlultiple-groove sheave will drive component such as air conditioner, generator and fan, the belt pulley race is more, and boundary dimension is bigger, weight is bigger, water pump life-span and engine performance there are adverse effect, influence water pump working life and engine performance, increase fuel consume and discharging.
Though existing spinning belt pulley substitutes the cast iron belt pulley structure, but it is technological difficulties that the cast iron belt pulley of many pulley grooves of step diameter is substituted by spinning belt pulley always, make many wedges spinning wheel and realize that the whole spinning of many pulley grooves of step diameter of belt pulley are very difficult, the mould pressing size of many pulley groove spinning belt pulleys of step diameter and the accuracy of form and position are difficult to realize that the life-span does not reach with the pump requirement yet.
Former thereby failures such as it all is many wedges spinning wheel that three-flute was done by some companies, by common welding and the flange exemplar that links, but all is because poor dimensional precision, and common welding deformation is big, and dynamometer life is short.
Summary of the invention
The utility model discloses a kind of combined type spinning belt pulley, present foundry goods belt pulley weight and rotary inertia are big to solve, spinning belt pulley once-through difficulty, problems such as size and accuracy of form and position difference.
The utility model combined type spinning belt pulley has many pulley grooves, it is characterized in that: comprise the main carrying drive part pulley groove with transmission shaft matching hole, do not have the drive part pulley groove of transmission shaft matching hole; Main carrying drive part pulley groove has the wall thickness and the structure of foundry goods, and the drive part pulley groove has the wall thickness and the structure of spinning.
The blue seam of main carrying drive part pulley groove general laws, the flange seam has the cylinder surface and with transmission shaft matching hole vertical Flange Plane coaxial with the transmission shaft matching hole; Drive part pulley groove endoporus cooperates radially spacing with the cylinder surface of main carrying drive part pulley groove flange seam; End face of drive part pulley groove cooperates axial limiting with the Flange Plane of main carrying drive part pulley groove.When having a plurality of drive part pulley groove, each drive part pulley groove has a counterface, can cooperate axial limiting with the Flange Plane of main carrying drive part pulley groove respectively, also can the stacked and main Flange Plane of carrying the drive part pulley groove of a plurality of drive part pulley groove counterfaces cooperate axial limiting.
Main carrying drive part pulley groove and drive part pulley groove are fastenedly connected.Its fastening means can be a bolton, rivets various known fastening means such as fastening.
Good effect of the present utility model is: the split combination, revolve the casting combination, and spinning falls heavily, and casting strengthens, and decomposition is simple, and combined and instant has been concentrated spinning spare and ironcasting advantage.Have in light weight, beautiful shape, little, the advantage of high production efficiency of rotary inertia, simple in structure, connect the good advantage of reliable, whole anufacturability.To cooling waterpump, can improve working life; For car load, can improve power performance, reduce oil consumption, reduce discharging.

Embodiment
Below be an embodiment of the present utility model.The utility model combined type spinning belt pulley has three pulley grooves, is applied on the auto pump, and three pulley grooves drive water pump, fan and driving generator, air-conditioning respectively.
As shown in Figure 1 and Figure 2: the utility model comprises the main carrying drive part pulley groove 1 with transmission shaft matching hole, does not have the drive part pulley groove 2 and 3 of transmission shaft matching hole; Main carrying drive part pulley groove 1 is an ironcasting, has the wall thickness and the structure of foundry goods, and drive part pulley groove 2 and 3 is two steel plate spinning spares, has the wall thickness and the structure of spinning.
The blue seam of main carrying drive part pulley groove 1 general laws, the flange seam has the cylinder surface and with transmission shaft matching hole vertical Flange Plane coaxial with the transmission shaft matching hole; Drive part pulley groove 2 and 3 endoporus cooperate radially spacing with the cylinder surface of main carrying drive part pulley groove 1 flange seam; Drive part pulley groove 2 and 3 respectively has a counterface, and the Flange Plane of the stacked and main carrying drive part of drive part pulley groove 2 and 3 counterface pulley groove 1 cooperates axial limiting.Two drive part pulley grooves 2 and the spinning wheel of wedge more than 3 be with the flange seam location on endoporus and the big plane of counterface and main carrying drive part pulley groove 1 cast-iron wheel, guarantees with the main endoporus that carries drive part pulley groove 1 cast-iron wheel coaxial.
Drive part pulley groove 2 is connected with main carrying drive part pulley groove 1 cast-iron wheel with 3 bolts by 6 M10 and forms the multiple ribbed pulley assembly of one three row's race.
Main carrying drive part pulley groove 1 is an ironcasting, satisfy belt pulley and connect requirement with the interference fit of water pump spindle, to transmit most power drive (the driving generator is that 3.8KW, driving air conditioner are that 3KW, drive fan are that 19KW, driving water pump are 2.5KW), intensity needs on the structure.
Drive part pulley groove 2 and the wheel of wedge more than 3 drive generator and air conditioner and make two steel plate spinning wheels, alleviate overall weight.
Various known fastening means structures such as the utility model is not limited to said structure, and its fastening means riveted joint is fastening also fall into protection domain of the present utility model.
