Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automation equipment, in particular to a bearing fixing structure for preventing slipping. Background Art
[0002] For logistics conveyor lines, the motor provides power to transmit the logistics line through the magnetic wheel installed on the drive shaft. The drive shaft will pass through the inner ring of the bearing of the bearing seat, and the bearing seat will be used to support the drive shaft. The number of bearing seats used is determined by the length of the drive shaft.
[0003] In the prior art, in order to prevent the inner ring of the bearing and the transmission shaft from slipping and to avoid wear of the transmission shaft, the inner ring of the bearing and the transmission shaft are fixed by transition fit assembly by controlling the machining tolerance of the inner ring of the bearing and the machining tolerance of the transmission shaft. However, this method is only applicable to scenarios where the transmission shaft is short and a small number of bearing seats are used. If the transmission shaft is longer, the number of bearing seats used will increase. Continuing to use the transition fit method to fit and fix the inner ring of the bearing and the transmission shaft will make it difficult to insert the transmission shaft into the inner ring of the bearing seat, and it will also be difficult to adjust the position of the bearing seat on the transmission shaft, which will increase the assembly cost. For longer transmission shafts, if a clearance fit method that is easier to assemble is selected, the inner ring of the bearing and the transmission shaft are prone to slipping, causing wear of the transmission shaft, thereby affecting the overall operation of the logistics conveyor line.

[0007] In a preferred embodiment of the utility model, fixing holes are respectively provided on both ends of the semicircular clamp, and the relatively opened and closed semicircular clamps are locked on the transmission shaft by tightening the fixing bolts after being matched; and the insertion of the fixing bolts does not interfere with the insertion trajectory of the transmission shaft through the fixing clamp.
[0008] In a preferred embodiment of the utility model, the spacers relatively arranged on both sides of the bearing are locked on the transmission shaft through fixed clamps on the outer sides of the spacers, and the spacers are pressed tightly against the inner ring of the bearing.
[0009] In a preferred embodiment of the utility model, the opening trajectory of the anti-loosening hole of the semicircular clamp and the opening trajectory of the clamping hole of the semicircular clamp are perpendicular to and intersect each other.
[0010] In a preferred embodiment of the utility model, the opening trajectories of the anti-loosening hole and the fixing hole of the semicircular clamp are parallel to each other.
