Problems solved by technology

[0003] One end of the gear shaft of the door closer is usually connected to the rocker arm. The connection between the gear shaft of the existing door closer and the rocker arm is usually square, and the rocker arm is provided with a corresponding square hole. The torque of this structure design is often insufficient. In addition, the connection between the gear shaft of the door closer and the rocker arm is easily damaged, which will reduce the service life of the product

Abstract

The invention relates to the technical field of gear shafts, in particular to a door closer gear shaft. The door closer gear shaft comprises a gear shaft body, the gear shaft body is integrally formed and comprises a shaft tooth part, a cylindrical part and connecting parts, the shaft tooth part is arranged in the middle of the gear shaft body, the connecting parts are arranged at the two ends of the gear shaft body, and the cylindrical part is arranged between the shaft tooth part and the connecting parts; and the outer diameter of the shaft tooth part is larger than that of the cylindrical part, the outer diameter of the cylindrical part is larger than that of the connecting parts, eight connecting teeth which are annularly arranged are evenly arranged on the periphery of each connecting part, a tooth groove is formed between every two adjacent connecting teeth, and a connecting threaded hole is formed in the end of each connecting part. According to the door closer gear shaft, the structural design is reasonable, the meshing area of the connecting portion of the gear shaft body and a rocker arm can be effectively increased, the attaching effect is good, damage is not likely to happen, the twisting effect between the rocker arm and the gear shaft body can be enhanced, and the service life of a product can be prolonged.

Description

technical field [0001] The invention relates to the technical field of gear shafts, in particular to a door closer gear shaft and a processing method thereof. Background technique [0002] The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door and can ensure that the door is closed to the initial position accurately and in time after it is opened. . Door closers are currently used mainly in commercial and public buildings. [0003] One end of the gear shaft of the door closer is usually connected to the rocker arm. The connection between the gear shaft of the existing door closer and the rocker arm is usually square, and the rocker arm is provided with a corresponding square hole. The design torque of this structure is often insufficient. In addition, the part where the gear shaft of the door closer is connected to the rocker arm is ...
