Abstract

The utility model discloses a high-strength gear, which comprises a gear body, wherein the gear body is of a hollow structure, internal teeth are arranged at the hollow position of the gear body, and external teeth are arranged on the periphery of the outer part of the gear body; the utility model has the advantages of reasonable design, convenient to use can effectively improve the intensity of gear to the life of gear has been prolonged.

Description

High-strength gear

Technical Field

The utility model belongs to the technical field of automobile parts and specifically relates to a high strength gear is related to.

Background

In traditional automobile parts, a gear is usually required to be used for transmission, and the gear is in a stressed state in real time due to long-term transmission, so that the gear is easy to wear or crack, the normal use of the gear is influenced, and the strength of the gear is required to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of proposing, provide a high strength gear for this reason, including the gear body, the gear body is hollow structure, the cavity position department of gear body is provided with the internal tooth, the outside a week of gear body is provided with the external tooth, the bottom of gear body is provided with the reinforcing disc, reinforcing disc and gear body structure as an organic whole that takes shape, the tooth angle density of internal tooth is greater than the tooth angle density of external tooth.

The utility model has the advantages that: the utility model has the advantages of reasonable design, convenient to use can effectively improve the intensity of gear to the life of gear has been prolonged.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic side view of the present invention;

in the figure: 1. a gear body; 2. internal teeth; 3. an outer tooth; 4. a reinforcing disk.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The high-strength gear comprises a gear body 1, wherein the gear body 1 is of a hollow structure, internal teeth 2 are arranged at the hollow position of the gear body 1, external teeth 3 are arranged on the periphery of the outside of the gear body 1, a reinforcing disc 4 is arranged at the bottom of the gear body 1, the reinforcing disc 4 and the gear body 1 are of an integrally formed structure, and the tooth angle density of the internal teeth 2 is greater than that of the external teeth 3.

In the using process, the thickness of the bottom of the gear can be reinforced by the reinforcing disc 4, so that the integral strength of the gear is improved, and the gear is effectively prevented from being cracked; the tooth angle density of internal tooth 2 is greater than the tooth angle density of external tooth 3, and the tooth angle density of internal tooth 2 is big on the one hand, can make the power that receives on each tooth angle reduce to reduce the wearing and tearing of internal tooth 2, the tooth angle density of external tooth 2 is little on the other hand, can make the clearance increase between the 2 tooth angles of external tooth, thereby makes the gear carry out the buffering of the clearance type of transmission in-process, thereby further reduction gear's wearing and tearing.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
