Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reaction flywheel rotor fixing tooling, in particular to a lifting clamping platform tooling for fixing a reaction flywheel rotor. Background Technique
[0002] As an attitude control actuator of a spacecraft, the reaction flywheel is required to have the characteristics of small volume, light weight, high reliability, etc. Therefore, the motor selected for the flywheel has the characteristics of small volume, light mass, small shaft diameter and no mounting hole position with the rotor. For the connection and fixation between the shaft and the rotor, glue bonding, interference fit (thermal difference method and press-in method), or machining mounting hole positions on the shaft are generally used. However, the latter two methods will weaken the strength of the shaft to a certain extent.
[0003] Using glue bonding and the thermal difference method can reduce the damage to the internal mechanical bearings of the motor to a certain extent. However, during assembly, a scale is needed to mark and determine the height position of the rotor assembly. Subsequently, the rotor is held by hand and inserted into the marked position of the shaft, or a spacer is embedded below the rotor before installation to ensure that the rotor can be installed at the target position. However, during actual assembly, manual errors are inevitable. Such errors not only make the fixed position of the rotor inaccurate but also cannot guarantee the coaxiality between the rotor and the shaft, resulting in problems such as poor consistency of the flywheels and rotor rotation drift during batch assembly. Embedding a spacer below the rotor installation position can avoid the influence caused by manual errors. However, after assembly, it is difficult to take out the spacer.
[0004] Therefore, there is an urgent need for a lifting clamping platform tooling for fixing a reaction flywheel rotor to solve the above problems. Content of the Utility Model
