Description

Technical Field

[0001] The utility model relates to the technical field of cigarette processing equipment, in particular to a connection structure of an active wheel assembly and a bearing seat of a European guide shuttle vehicle. Background Art

[0002] Cigarette manufacturers widely use box-type tobacco storage equipment for transporting finished tobacco. The Oudao shuttle car is a semi-automatic shuttle car designed for high-density, multi-depth storage of finished tobacco boxes, capable of operating within three-dimensional aisles. Its advantages include addressing dense storage and rapid access, significantly increasing storage density and significantly reducing tobacco warehouse construction costs. The Oudao shuttle car utilizes a four-wheel drive, eight-wheel structure, with four active wheels in the front, rear, and left and right directions. Each active wheel drives a passive wheel via a chain drive, ensuring even power distribution, strong driving force, and stable operation under load.

[0003] In the actual production process, the European shuttle car often encounters the problem of the active wheel assembly being disengaged from the bearing seat. The reason is that the bearing is limited by the external retaining spring on the outside of the main drive shaft of the active wheel assembly. During operation, the main drive shaft of the active roller sprocket undergoes axial movement, which will cause the external retaining spring on the main drive shaft to be separated from the retaining spring groove on the main drive shaft due to the axial force, causing the active roller sprocket and the active wheel to immediately fall off the track, affecting normal production and posing a major safety hazard. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a connection structure between the active wheel assembly and the bearing seat of the European Guide shuttle vehicle, so as to effectively prevent the active wheel assembly from falling off the track and eliminate safety hazards.

[0005] The utility model is realized through the following technical solutions:

[0006] A connection structure between a driving wheel assembly and a bearing seat of a European guide shuttle car, the driving wheel assembly includes a driving roller sprocket and a driving wheel that are coaxially fixedly installed. A main drive shaft is provided at one end of the driving roller sprocket, and the main drive shaft is rotatably mounted on the bearing seat through a bearing. A mounting channel is provided inside the bearing seat, and a bearing is provided in the mounting channel of the bearing seat. A limiting convex ring is provided at the inner end of the mounting channel of the bearing seat, and a retaining spring is provided at the position of the mounting channel of the bearing seat near the outer end. The inner and outer sides of the outer ring of the bearing are limited by the limiting convex ring and the retaining spring. The main drive shaft extends from the inside to the outside of the bearing inner hole, and a section of the outer end of the main drive shaft extending out of the bearing is the extending section. An external threaded section is provided on the extending section of the main drive shaft, and a locking nut is threadedly sleeved on the external threaded section of the main drive shaft, and the outer limit position of the inner ring of the bearing on the main drive shaft is limited by the locking nut.

[0007] As a preferred solution of the above-mentioned connection structure, the main transmission shaft is also provided with a backstop washer, which is located between the locking nut and the bearing. A plurality of openings are provided on the outer circumference of the locking nut, and the stop ears of the backstop washer cooperate with the openings of the locking nut.

[0008] As a preferred solution of the above-mentioned connection structure, four openings are evenly distributed on the outer circumference of the locking nut.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The utility model provides a connection structure between the active wheel assembly and the bearing seat of a European guide shuttle vehicle. A locking nut is threaded onto the externally threaded section of the main drive shaft. The locking nut limits the outer limit position of the bearing inner ring on the main drive shaft, effectively preventing the main drive shaft from disengaging from the bearing, thereby preventing the active wheel assembly from derailing, eliminating safety hazards and ensuring the safe operation of the equipment. Furthermore, a retaining washer is provided between the retaining nut and the bearing. The retaining ear of the retaining washer cooperates with the opening of the locking nut, effectively preventing the nut from loosening, ensuring a secure connection between the two, and further ensuring the limiting effect on the bearing.
