Gear and shaft matching
Dynamic fit connection, that is, the gear rotates radially and moves axially and rotates on the shaft. For example: the gear rotates on the shaft and is connected through bearings (or bushings)
The gear can move radially on the shaft and rotate with the coaxial shaft.
1. Such as spline shaft connection.
2. Static fit connection, that is, the gear is fixed on the shaft and rotates with the shaft. For example: the shaft and gear are slotted and fixed with keys. For example: interference fit connection, that is, the gear hole is heated and the gear is fixed on the shaft by thermal expansion and contraction.
3. Gears are processed on the shaft, that is, the gear and shaft are integrated.
Characteristics of gear and shaft transmission
Gear and shaft transmission has the advantages of relatively large transmission power, stable torque, adjustable transmission ratio, low noise, high reliability, easy installation and maintenance, and meeting the requirements of low transmission rate and high precision under different powers.
Selection of gear and shaft transmission
The selection of gear and shaft transmission devices should take into account the load type and load size required by the design, the required input and output speeds, transmission accuracy, and gear and bearing load capacities.
Notes on installing gears and shafts
When installing the transmission device, attention should be paid to the gear model, number of gear teeth, pressure angle of the gear, installation accuracy of the shaft, bearing and gear, and connection method between the gear and the shaft seat, etc. During the installation process, it is important to avoid damaging parts, increasing noise, and reducing transmission accuracy.
Technical requirements for repairing gears and shafts
When repairing gear and shaft transmission devices, technicians should be required to have professional knowledge and skills to fully identify and evaluate the faults of gear and shaft transmission devices, and ensure the quality of repair after disassembly, cleaning, inspection, and assembly.
Gear and shaft transmission methods are very common. In the selection, installation and maintenance of gear and shaft transmission devices, many technical requirements should be kept in mind to ensure the normal operation and maximum efficiency of the device.
