Supporting-catch wheel with external refueling device

Abstract

The invention discloses a supporting-catch wheel with an external refueling device. The lower end of a catch wheel upper seat (6) is sleeved in a catch wheel lower seat (8). Lower bearings (10) and upper bearings (5) are arranged between the lower end of the catch wheel upper seat (6) and the catch wheel lower seat (8). Sealed pads (12) are arranged between an outer ring of the catch wheel upper seat (6) and the catch wheel lower seat (8). Ring covers (7) are arranged at the upper ends of the sealed pads (12). An inner cover (4) is arranged at the upper end of the catch wheel lower seat (8). An outer sealed cover (2) is arranged at the upper end of the catch wheel upper seat (6). An oil cup (1) is arranged on the outer sealed cover (2). Connecting shafts (9) are arranged on two side portions of the catch wheel lower seat (8). The catch wheel lower seat (8) and hydraulic cylinders are connected through the connecting shafts (9). A guiding-out oil pipe (11) penetrates through the upper end of the center portion of the catch wheel lower seat (8) and the inner cover (4) from bottom to top in sequence. The upper end of the guiding-out oil pipe penetrating out of the inner cover (4) is fixedly connected by an upper nut (3). A gap is left between the upper nut (3) and the outer sealed cover (2).

Description

technical field [0001] The invention relates to a supporting and retaining wheel structure of a carbon rotary kiln. Background technique [0002] Generally, the rotary kiln is a thermal equipment for heat treatment of bulk materials, and its production process is carried out at high temperature and in rotation. The kiln body of the rotary kiln is supported by the supporting device, and the number of supporting wheels and retaining wheels in the supporting device is determined according to the size and length of the kiln body. One of the gears is equipped with a supporting wheel with a retaining wheel, which is called a retaining wheel. Due to the axial movement of the kiln body, the supporting wheel only serves as a support, and the retaining wheel serves to limit the axis of the kiln body within the allowable range. To the role of movement. In the structure of the retaining wheel, the supporting wheel is on both sides, and the retaining wheel is in contact with the rollin...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a retaining wheel with an external oiling device to overcome the inconvenient refueling of the bearing in the retaining wheel existing in the prior art, which may easily cause damage to the bearing and affect the normal operation of the carbon rotary kiln. Insufficient running etc.
