Information Summary:

The mechanical properties of the selection of hardened gears are the mechanical transmission elements that should be used in a gear reducer.

A hardened gear reducer is a mechanical transmission element used in a gearbox..... A gear transmission transmits motion and power between any two shafts in space through the engagement of gear teeth, which can change the shape and speed of movement. The gear train has a wide range of applications, and its gear ratio is constant. It is highly efficient and has a long service life. In the process of designing and manufacturing mechanical parts, it is necessary not only to take into account the properties of the material in order to adapt it to the working conditions of the parts and make them durable. Better machinability and cost-effectiveness of the material are also needed to increase the productivity of the parts.

How to choose gears for hardened gears?

The mechanical properties of the selection of hardened gears are the mechanical transmission elements that should be used in a gear reducer. A gear train transfers motion and power between any two shafts in space through the engagement of gear teeth, which can change the shape and speed of movement. Gears have a wide range of applications. The gear ratio is constant. They are highly efficient and have a long service life. In the process of designing and manufacturing mechanical parts, it is necessary not only to take into account the properties of the material in order to adapt it to the working conditions of the parts and make them durable. Better machinability and cost-effectiveness of the material are also needed to increase the productivity of the parts. As a result, costs and material consumption are reduced. If the material for the gears is selected incorrectly, the part may fail prematurely or even break. Therefore, the reasonable choice and use of metal materials is a very important topic.

It meets the mechanical properties of a hardened gear reducer, including strength, hardness, ductility and viscosity. And this reflects the characteristics of the materials used. When the gear engages, contact stresses occur on the contact part of the tooth surface, and large bending stresses occur on the root of the tooth, which can lead to a decrease in the strength of the tooth surface or its body. Each point on the tooth surface slides relative to each other, causing wear. The main types of destruction of gears are point wear, tooth jamming, plastic deformation of the tooth and tooth destruction. Therefore, high bending fatigue strength and contact fatigue strength are required from the gear material, the tooth surface must have sufficient hardness and wear resistance, and the core must have a certain degree of strength and viscosity.

In accordance with the properties of the material, determine its brand. It is necessary to determine the mechanical properties or hardness of the material, and then achieve the required hardness range through various heat treatment processes, giving the material different mechanical properties. The machinability of a material is its ability to adapt to different processing requirements. Hardened gearbox gears are made by forging, cutting and heat treatment, therefore, when choosing a material, attention should be paid to its machinability. As a rule, carbon steel lends itself well to forging and cutting, and its mechanical properties can meet the requirements of general working conditions.

The role of a hardened gear reducer in the operation of the crane

A hardened gear reducer is a drive transmission mechanism that uses the variable speed of the transmission mechanism to reduce the speed of the motor to the required speed to obtain more torque. In modern mechanisms of energy transfer and fitness, the range of gearboxes has become quite wide.

Basically, it can be seen in the transmission of various mechanical equipment, ranging from vehicles, ships, automobiles, electric locomotives, medium and heavy-duty machines used in mechanical engineering, technological equipment widely used in mechanical engineering, and ending with automation technology. Currently, in Russia and abroad, electric drives are used in mechanical engineering, in automation technologies, as well as in household appliances and quartz watches in everyday life. The range of application is shifting from high driving force to low load. The areas of its application can be seen. In industrial production, the speed reducer performs the functions of slowing down and increasing torque. Therefore, it is widely used in mechanical equipment to convert speed and torque.
