In order to match the center distance or improve the transmission capacity and efficiency of the worm gear hard tooth surface reducer.

Generally, displacement worm gear transmission is used.

The displacement method is similar to that of a transmission gear.

During the entire drilling process, the axial displacement of the CNC blade relative to the blank is used to maintain displacement. However, in worm gear transmission, because the tooth profile and specifications of the worm should be the same as the shape and specifications of the pressurized rolling cutter being produced and processed, in order to maintain the specifications of the CNC blade unchanged, the specifications of the worm cannot be changed, so only the worm gear can be modified.

After displacement, the indexing circle and pitch circle of the boost still overlap.

The pitch line of the worm gear changes greatly in the middle plane view, and the degree lines between the two no longer overlap.

According to the application status of the worm controller, there are two ways to change its position.

1.

Before and after displacement, the number of worm gear teeth will not change, and the center distance of worm gear transmission will change.

2. Displacement before and after left and right.

The center distance of the worm gear transmission remains consistent, and the number of teeth on the worm gear varies greatly. The number of heads on the worm gear is related to the output power of the transmission.

The larger the number of magnetic heads, the greater the output power of the transmission, and the greater the output power of the worm drive, which is equivalent to the transmission of fitness and output power between two overlapping shafts in indoor space. The intersection angle between the two shafts can be arbitrary, usually 90 °.

Needle wheel deceleration is a device that slows down the number of rotations of an electric motor to the desired number of rotations and obtains a large torque.

A reducer is a relatively high-precision mechanical equipment, which is used to reduce the speed ratio and increase the torque.

The needle wheel reducer is based on the basic principle of rotary wheel line needle tooth combination and large planetary transmission, so it is generally also known as a large planetary hard tooth surface reducer.

This transmission has advantages such as compact structure, large reduction ratio, smooth transmission, and locking against the spectrum under certain standards.

The market is applied in industrial equipment such as CNC lathes, small cars, instrumentation, heavy-duty machinery, and metallurgical machinery.

The reliability design of worm gear transmission at North China Electric Power College. Tang Jinru's worm gear and worm gear can transmit fitness exercises and output power between two overlapping shafts in indoor space.

Due to its advantages such as large reduction ratio and compact structure, it has been widely used in various industrial equipment transmission devices.

The article provides a detailed introduction to the reliability design methods and values of basic parameters in general cylindrical worm gear transmission design schemes based on actual cases.

Because there is currently no complete calculation method for adhesive damage, standard calculations are still carried out based on the contact fatigue limit of the tooth surface and the bending fatigue limit of the gear teeth. Only the hazards of adhesive and damage are considered in the allowable stress values.

The reducer manufactured by the reducer manufacturer has the function of pairing the speed ratio and transmission torque between the transmission device and the working machine or electric actuator, and is a relatively high-precision mechanical equipment.

The purpose of applying it is to reduce the speed ratio and increase the torque.

It has a wide variety of varieties, different models and specifications, and different types have different main uses.

There are various types of reducers, which can be divided into gear reducers, worm reducers, and large planetary gear reducers according to the type of transmission; According to the different transmission ratios and stages, it can be divided into single pole and multi-stage reducers; According to the shape of the transmission gear, it can be divided into cylindrical gear reducers, cone gear reducers, and cone cylindrical gear reducers; According to the layout of the transmission, it can be divided into unfolded, separated, and coaxial reducers.

The compressive strength of worm gear raw materials is generally higher than that of worm gear raw materials, and the worm gear is a continuous spiral tooth, so the ineffectiveness of the worm gear pair usually occurs on the worm gear.

Generally, only the bearing capacity of the worm gear is measured.

Worms are usually long and thin shafts, and excessive bending deformation can cause looseness in the meshing area.

Therefore, when the span of the support plate of the worm is large, the bending stiffness of the worm should be corrected.

The table lists the basic specifications and main parameters for standardizing general cylindrical worm gear transmissions.

When designing a general cylindrical worm speed reduction device, the center distance of the worm is determined based on the contact compressive strength or bending compressive strength, and the specifications and main parameters of the worm and boost are determined based on the statistical data in the table.
