CN202659703U - Gear shaft - Google Patents

Abstract

The utility model provides a gear shaft comprising a shaft body, and wheel teeth connected with the shaft body, wherein a key slot and a groove are formed at one end of the shaft body, and the included angle between the key slot and the groove in a radial direction is 80-180 degrees. In the gear shaft provided by the utility model, the key slot and the groove are arranged at one end of the shaft body, the key slot is matched with a key to realize radial location for a gear, and the groove is matched with a pin and the like to realize axial location, thus improving the flexibility of the gear shaft, reducing the rejection rate during a production process, and reducing the production cost.

Description

A kind of gear shaft

Technical field

The utility model relates to a kind of gear shaft.

Background technique

Gear shaft refers to support the mechanical parts that rotational parts also turns round to transmit motion, moment of torsion or moment of flexure therewith.Gear shaft be widely used in producing and the various machinery of living on.Existing gear shaft generally carries out axially locating by the shaft shoulder and axle sleeve, because the position of the shaft shoulder is fixing in the course of working, therefore the position of coupling gear is also relatively fixing, when gear shaft excessive error occurs in course of working, this gear shaft is scrapped, flexibility is low, has increased cost of production.

The model utility content

The technical problem that (one) will solve

The technical problems to be solved in the utility model provides the adjustable gear shaft of a kind of gear position.

(2) technological scheme

For solving the problems of the technologies described above, the utility model provides a kind of gear shaft, comprises axis body 1 and the gear teeth 2 that link to each other with described axis body 1, and described axis body 1 one ends are provided with keyway 3 and groove 4, and described keyway 3 and described groove 4 angle diametrically are 80 ° ~ 180 °.

Further, described keyway 3 and described groove 4 angle diametrically are 90 °.

Further, described axis body 1 and the described gear teeth 2 edge chamfers.

Further, the length of described groove 4 is less than the length of described keyway 3.

(3) beneficial effect

The utility model gear shaft is provided with keyway and groove at axis body one end, and the keyway fit key is realized the radial location of gear, groove fit pins etc. are realized axially locating, improve the flexibility ratio of gear shaft, reduced the scrappage of appearance in process of production, reduced cost.

Description of drawings

Fig. 1 is the structural representation of the utility model gear shaft;

Fig. 2 is the plan view of the utility model gear shaft.

Embodiment

Consult Fig. 1 ~ Fig. 2, the utility model provides a kind of gear shaft, comprise axis body 1 and the gear teeth 2 that link to each other with axis body 1, axis body 1 and the gear teeth 2 are one-body molded, axis body 1 and the gear teeth 2 are at edge chamfer, this chamfering has been removed burr and the sharp edge that produces in course of working, the wedge angle distortion that also having reduced collides with causes, chamfering on the axis body 1 can be used as the Setup Wizard of gear, end at axis body 1 is provided with a keyway 3, keyway 3 is realized the radial location of gear is installed by key, also be provided with a groove 4 in axis body 1 one sides, groove 4 is 90 ° with keyway 3 angle diametrically, and the length of groove 4 is less than the length of keyway 3, and groove 4 realizes installing the axially locating of gears by pin etc.

The utility model gear shaft is provided with keyway and groove at axis body one end, and the keyway fit key is realized the radial location of gear, groove fit pins etc. are realized axially locating, improve the flexibility ratio of gear shaft, reduced the scrappage of appearance in process of production, reduced cost.

The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims (4)

1. gear shaft, comprise axis body (1) and the gear teeth (2) that link to each other with described axis body (1), it is characterized in that: described axis body (1) one end is provided with keyway (3) and groove (4), and described keyway (3) and described groove (4) angle diametrically are 80 ° ~ 180 °.
