Abstract

The utility model relates to the technical field of machinery, in particular to a self-adaption type gear which comprises a gear ring, gear teeth and a shaft hole, wherein the gear ring is connected with the gear teeth in positioning mode, the shaft hole is arranged in the middle of the gear ring, the gear teeth are fixed on a gear tooth ring, the gear tooth ring is connected with the gear ring in positioning mode, fixing grooves are arranged in the gear tooth ring, fixing blocks are arranged on the gear ring, the fixing grooves are matched with the fixing blocks, the gear tooth ring is inserted into the fixing grooves through the fixing blocks so that the aim that the gear tooth ring is fixedly connected with the gear ring is achieved, the number of the fixing grooves is one or more than one, and the number of the fixing grooves is consistent with that of the fixing blocks. The self-adaption type gear can aim at bearing rods of various sizes, so that on the basis of using the same gear, people only need to change gear rings of different shaft holes and do not need to change the whole gear. The self-adaption type gear has the advantages of saving cost and improving efficacy.

Description

A kind of self-adaptive type gear

Technical field

The utility model relates to a kind of field of mechanical technique, especially a kind of self-adaptive type gear.

Background technique

Gear is a kind of common mechanical transmission part, because the axis hole of gear must just can be installed and used by the fitted bearing bar, so the bearing rod for different size just needs to be equipped with its gear that matches, and will certainly increase cost like this, is unfavorable for the raising of working efficiency.

The model utility content

In order to overcome the high deficiency of existing gear replacement cost, the utility model provides a kind of self-adaptive type gear.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of self-adaptive type gear, comprise gear ring, teeth and axis hole, and gear ring and teeth are located by connecting, and are provided with axis hole in the middle of the gear ring, and teeth are fixed on the teeth ring, and teeth ring and gear ring are located by connecting.

According to another embodiment of the present utility model, comprise that further the teeth ring is provided with fixed groove, gear ring is provided with fixed block, and fixed groove and fixed block are complementary, and the teeth ring inserts fixed groove by fixed block and realizes and being fixedly connected with of gear ring.

According to another embodiment of the present utility model, comprise that further fixed groove quantity is one or more, fixed groove quantity is consistent with fixed block.

The beneficial effects of the utility model are that this gear can only be changed the gear ring of different axis holes, and need not change whole gear for the bearing rod of different size on the basis of using same gear, saved cost, has improved effect.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a kind of structural representation of self-adaptive type gear;

1. gear rings among the figure, 2. teeth, 3. axis hole, 4. teeth ring, 5. fixed groove, 6. fixed block.

Embodiment

A kind of structural representation of self-adaptive type gear such as Fig. 1, a kind of self-adaptive type gear, comprise gear ring 1, teeth 2 and axis hole 3, gear ring 1 is located by connecting with teeth 2, be provided with axis hole 3 in the middle of the gear ring 1, teeth 2 are fixed on the teeth ring 4, teeth ring 4 is located by connecting with gear ring 1, teeth ring 4 is provided with fixed groove 5, gear ring 1 is provided with fixed block 6, and fixed groove 5 is complementary with fixed block 6, and teeth ring 4 inserts fixed grooves 5 by fixed block 6 and realizes and being fixedly connected with of gear ring 1, fixed groove 5 quantity are one or more, and fixed groove 5 quantity are consistent with fixed block 6.

When if the axis hole of this gear 3 can't mate current bearing rod, only need to be the fixed groove 5 interior traversing taking-ups of the fixed block 6 on the gear ring 1 from the teeth ring 4, replacing with the gear ring 1 that is complementary with bearing rod gets final product, the bearing rod that so just can adapt to the gear of same teeth 2 different size, and when having teeth to damage on the gear, also only needing to change teeth ring 4 gets final product, do not need to replace whole gear, this gear can be for the bearing rod of different size, on the basis of using same gear, only change the gear ring of different axis holes, and need not change whole gear, and saved cost, improved effect.
