The difference in the form of the shaft hole of the elastic pin gear coupling

作者: Published: 2020-01-18

The difference in the form of the shaft hole of the elastic pin gear coupling:

Y type represents cylindrical shaft hole

Type J represents a short cylindrical shaft hole with a counterbore

J1 type represents short cylindrical shaft hole without counterbore 

Although there are many types of elastic pin gear couplings, each type of elastic pin gear coupling has its own principle and characteristics, but some of their basic conditions are still the same.

In the structural design and series design of various types of elastic pin gear couplings, determine the specifications of the elastic pin based on the size of the transmission torque, the structure of the elastic pin gear coupling and the strength of the hub. For the shaft hole range (maximum and minimum shaft hole) and length of the shaft hole of the gear coupling, there is only one shaft hole length for each specification.

Shafting transmission usually consists of one or several elastic pin gear couplings connecting the main and driven shafts to form a shafting transmission system to transmit rotation or movement.The elastic pin gear coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole form, connection form and size mainly depend on the type and size of the connected shaft. The product design is generally based on cylindrical and Conical shaft depth international standard design shaft, shaft depth standard is for shaft design.

In foreign countries, all enterprises producing elastic pin gear couplings in different countries are the only one of each specification of elastic pin gear couplings in the standards of different elastic pin gear couplings. Length of shaft hole.Due to the misleading of GB/T3852, each specification in my country's elastic pin gear coupling product standard corresponds to a variety of shaft hole lengths as the shaft hole changes. The foreign elastic pin gear coupling When the standard is converted into the Chinese standard, a variety of shaft hole lengths are added. It seems that this is the only way to be considered a complete conversion.
