Quasi-hyperbolic gear manufacturers take you to understand quasi-hypoid gears

Gear in all areas of our lives have many contacts, small precision mechanical watches, aerospace, almost all industry-related fields have its shadow. Today, the quasi-hyperbolic gear manufacturer will briefly introduce the hypoid gear widely used in the automobile transmission system. There are many types of gears, including spur gears, bevel spur gears, bevel gears, and the hypoid gears introduced today.

Quasi hyperbolic gear manufacturers share the characteristics of quasi hypoid gear:

First, the hypoid gear's axial cross angle of 90 can change the torque direction to 90 degrees, which is also an angle conversion often required by the automotive, aircraft or wind power industries. At the same time, a pair of gears with different sizes and different numbers of teeth mesh together to increase torque and reduce speed, which is commonly referred to as "increasing torque and reducing speed". Friends who drive, especially when learning to drive, when driving a manual car, when climbing a hill, the coach will let you walk in the low position. In fact, it is to choose a pair of gears with relatively large speed. It is to provide more torque at low speeds to provide more power to the vehicle.

What are the characteristics of quasi-hyperbolic gear manufacturers?

Torque angle change transmission

As described by the quasi-hyperbolic gear manufacturer, this is an angular change in torque power that can be achieved.

Can withstand greater load

The use of this type of wind power industry, automobile industry, cars, SUVs, commercial vehicles, small trucks and buses provides greater power.

Smoother transmission, less noise

The pressure angle on the left and right sides of the tooth may be inconsistent. When the gear meshes, the sliding direction is along the tooth width and gear profile direction. The design and process can improve the gear meshing position. Even if the entire transmission is under load, it can maintain good NVH performance.

Offset can be adjusted

Due to the different design of the offset, it can be used to meet various space design requirements such as automobiles. For example, it can meet the distance interval requirements of vehicles and improve the passability of vehicles.

Quasi-hyperbolic gear manufacturers share quasi-hyperbolic gear processing methods

Quasi-double-sided gear has been developed for many years, at present, there are many domestic equipment can be processed, but high precision advanced processing is mainly foreign equipment Gleason and Olikang equipment. In the field of finishing mainly grinding process and grinding process, but the cutting process requirements are different. For the grinding process, quasi-hyperbolic gear manufacturers recommend the use of tight ring type, grinding recommended the use of cotton coil cutting process.

Gears machined with face milling are gradually reduced teeth, face rolling profile teeth. That is, the tooth heights of the large and small end faces are the same. The general processing process is generally thermal electrical processing, heat treatment and then finishing. For the face rolling Face Hob type, the pair needs to be ground after opening. Usually, the gears ground together still need to be kept in pair when assembling later. However, the gears in the finishing process of the polishing process do not need to be paired in theory, but in actual work, considering the influence of assembly errors and system deformation, the pairing mode is still used.

The design and development of hypoid is more complicated, especially in advanced products with high conditions of use or requirements, the strength, noise, transmission efficiency, weight, and size of gears are required. Therefore, quasi-hyperbolic gear manufacturers believe that in the design stage, it is usually necessary to combine various factors to find a balance through iteration. In the development process, it is usually necessary to adjust the tooth mark within the allowable change range of the component, so as to achieve the required performance level due to the accumulation of dimension chains, system deformation and other actual conditions.
