How to disassemble and assemble bearing components inside a manual hydraulic transport vehicle
The manual hydraulic handling vehicle has the functions of short distance transportation and short distance lifting of heavy objects. It has a small turning radius, flexible steering, can pass through narrow elevator passages, and can also handle goods on spacious and flat roads. The flexibility of the bearings inside the transport vehicle during operation is also related to its operational flexibility.
Rolling bearings are installed inside the wheels of manual hydraulic transport vehicles, making push-pull travel lighter. High quality radial roller bearings are also installed at the connection of the rotating shaft, which are flexible and not shaking. It can be said that the support structure of the bearings plays an important role in ensuring the rotation accuracy of the shaft and fully utilizing the application characteristics of the transport vehicle.
One of the reasons for early damage to bearings is incorrect installation and disassembly methods. Therefore, when designing the support, it is necessary to consider how the bearings are assembled and disassembled, as well as the issue of ease of assembly and disassembly. The installation and disassembly methods of bearings should be determined according to the structure, size, and fitting properties of the bearings.
In general, the assembly and disassembly of bearings are mainly carried out through two ways; One is to press the interference fit ring into the shaft or into the bearing seat hole; The second method is to heat the bearing to expand its inner diameter, or cool the bearing to reduce its outer diameter, making it easy to install the bearing on the shaft or push it into the seat hole. However, regardless of the method used, it is not allowed to directly strike the bearing ring, cage, rolling parts or seals, and installation force cannot be transmitted through the rolling elements.
The process of installing bearings for manual hydraulic transport vehicles is also the process of adjusting bearing clearance. Bearing installation can be done using mechanical, heating, or hydraulic methods.
