Description

Eccentric wheel

Technical Field

The utility model belongs to the technical field of mechanical equipment accessory and specifically relates to an eccentric wheel.

Background

The eccentric wheel is provided with a plurality of wheel-shaped parts on the shaft, the shaft hole deflects to one side, when the shaft rotates, the outer edge of the wheel pushes another machine part to generate reciprocating motion, and the eccentric wheel is used for driving a mechanical switch, a valve and the like; however, most eccentric wheels cannot adjust the clamping force when being matched on the shaft, so that the eccentric wheels have the possibility of loosening; the eccentric wheel is used as an important connecting part and needs to be connected with various accessories, and the different shapes of the accessories influence whether the accessories can be matched with the eccentric wheel; therefore, there is a need for an improved eccentric structure.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to above-mentioned technique is not enough, provides a second mating holes can pair the use with the accessory of different shapes, and the accessible lets in the pin to the bolt hole and installs other accessories on the eccentric wheel, realizes the accessory assembly of different positions, and the accessible lets in the bolt in to the screw and carries out the adjustment to leading to groove clearance size to adjust the eccentric wheel of the firm degree between the fixed axle in eccentric wheel main part and the first mating holes.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:

the utility model provides an eccentric wheel, is including being circular form eccentric wheel main part, set up in the eccentric wheel main part be used for with fixed axle complex first mating holes, with set up the second mating holes in the eccentric wheel main part that first mating holes position is relative, logical groove has been seted up in the eccentric wheel main part of first mating holes one side, lead to the lateral wall that the groove both ends run through the eccentric wheel main part respectively and the lateral wall of first mating holes, all seted up the screw on the eccentric wheel main part wall that leads to the groove both sides, the bolt hole has been seted up on the eccentric wheel main part wall of one side in the first mating holes.

Furthermore, the first matching hole is a circular through hole, and the second matching hole is a crescent through hole.

Furthermore, the screw hole on one side penetrates through the second matching hole, a third matching hole is formed in the wall surface of the eccentric wheel main body on the outer side of the screw hole on the other side, the third matching hole is communicated with the screw hole, and the radius of the third matching hole is larger than that of the screw hole.

The utility model has the advantages that: the second mating holes can be paired with accessories of different shapes for use, other accessories are installed on the eccentric wheel through introducing pins into the bolt holes, the assembly of accessories in different positions is achieved, the adjustment of the size of the gap of the through groove is performed through introducing bolts into the screw holes, and therefore the firmness degree between the eccentric wheel main body and the fixed shaft in the first mating holes is adjusted.

Drawings

Fig. 1 is a perspective view of the present invention.

Fig. 2 is a top view of the present invention.

Fig. 3 is a cross-sectional view in the direction a.

In the figure, an eccentric wheel body 1, a first matching hole 2, a second matching hole 3, a through groove 4, a screw hole 5, a bolt hole 6 and a third matching hole 7.

Detailed Description

As shown in fig. 1 ~ 3, an eccentric wheel comprises an eccentric wheel body 1 in a circular shape, wherein a first matching hole 2 matched with a fixed shaft is formed in the eccentric wheel body 1, a second matching hole 3 is formed in the part, opposite to the first matching hole 2, of the eccentric wheel body 1, a through groove 4 is formed in the eccentric wheel body 1 on one side of the first matching hole 2, two ends of the through groove 4 penetrate through the side wall of the eccentric wheel body 1 and the side wall of the first matching hole 2 respectively, screw holes 5 are formed in the wall surfaces of the eccentric wheel body 1 on two sides of the through groove 4, and a bolt hole 6 is formed in the wall surface of the eccentric wheel body 1 on one side in the first matching hole 2.

The first matching hole 2 is a circular through hole, and the second matching hole 3 is a crescent through hole.

The screw hole 5 on one side penetrates through the second matching hole 3, a third matching hole 7 is formed in the wall surface of the eccentric wheel main body 1 on the outer side of the screw hole 5 on the other side, the third matching hole 7 is communicated with the screw hole 5, and the radius of the third matching hole 7 is larger than that of the screw hole 5.

When in use:

a fixed shaft (not shown in the figure) is matched in the first matching hole 2, then a bolt (not shown in the figure) is introduced into the screw hole 5 along the third matching hole 7 until the head of the bolt enters the third matching hole 7, the depth of the bolt entering the screw hole 5 is adjusted by rotating the adjusting bolt, so that the size of a gap of the through groove 4 is adjusted, the clamping force of the wall surface of the eccentric wheel main body 1 in the first matching hole on the fixed shaft is adjusted, and the matching and the separation between the eccentric wheel main body 1 and the fixed shaft are realized; the second fitting hole 3 can be used in a matching way with fittings (not shown) of different shapes, and other fittings can be arranged on the eccentric wheel body 1 by introducing pins (not shown) into the bolt holes 6.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
