Description
Technical Field
The utility model relates to an universal wheel installation mechanism especially relates to a movable truckle installation axle.
Background
Some special vehicles use movable casters (universal wheels) for steering or pivot steering, and the movable casters (universal wheels) need vertical shafts to support the weight of the vehicle.
Currently, there are several common ways:
1. deep groove ball bearings, which are capable of bearing limited axial forces;
2. tapered roller bearings, but without spacer bushes, each require the torque of the threads to be debugged;
3. the powder metallurgy spacer bush serves as a bearing, steel rubs iron, and abnormal sound cannot be generated after a long time;
4. the thrust ball bearing can bear axial force and cannot bear radial force.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a movable truckle installation axle.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a movable truckle installation axle, including the pivot, the bearing frame, first tapered roller bearing, second tapered roller bearing, the spacer, the bolt, spring washer, first tapered roller bearing and second tapered roller bearing are fixed in the pivot both ends respectively, the bearing frame cover is established outside first tapered roller bearing and second tapered roller bearing, the bearing frame lower extreme is provided with the oil blanket, the bearing frame upper end is provided with the shield, the pivot upper end is provided with the bolt hole, the bolt passes spring washer and shield and bolt hole cooperatees, the spacer setting is between first tapered roller bearing and second tapered roller bearing.
Furthermore, a first step and a second step are arranged on the lower portion of the rotating shaft, the oil seal is located on the second step, and the second tapered roller bearing is located on the first step.
Furthermore, clamping grooves are formed in two ends of the bearing seat, and the first tapered roller bearing and the second tapered roller bearing are respectively located on the clamping grooves.
Further, a flat gasket is arranged between the spring gasket and the dust cover.
Compared with the prior art, the utility model discloses a tapered roller bearing can bear bigger axial force and radial force simultaneously, increases simultaneously between two bearing inner circles and applys torsion locking after the spacer, has avoided carrying out torsion regulation to two bearings respectively, has simplified the structure, guarantees that two bearing torsion are the same, does not produce the abnormal sound, improves life.
