Furthermore, a counterweight wheel is arranged between the elevator ground wheel and the elevator tail section shell, and the counterweight wheel and the elevator ground wheel are connected with the tail shaft through flat keys.
Further, the sealing material is a sealing rubber strip.
The beneficial effect of this application does:
1. thoroughly eliminated the noise phenomenon that the tailwheel vibrations appear and lead to, chinese patent CN201721285276.4 among the background art, for its discovery in the use of this company's applied patent, including after lead screw and nut, because of receiving the effort of nut, the left and right sides bearing frame is not on a horizontal plane, local contact between wear-resisting alloy overcoat spare and the wear-resisting alloy internal member during the operation, cause unilateral wearing and tearing and produce the noise, and new construction has cancelled lead screw nut, the discovery only leans on counter weight wheel spare equally can the tensioning chain, the problem is exactly gapped between lead screw and the casing in addition, can follow this clearance during the transportation material and overflow dust and material, sealed effect is more effective after the cancellation.
2. All the devices are sealed in the shell body, and no dust overflow point exists. The novel structure seals all equipment inside the shell, the access hole is in bolted connection with the angle steel flange frame, the rubber sealing strip is pressed in the middle, no matter powder or block-shaped materials are conveyed, no dust is raised outside the shell, and the field environment is greatly improved.
3. The wear-resistant alloy inner sleeve and the tail shaft are connected by adopting a more reliable flat key structure. The relative position of the wear-resistant alloy internal sleeve and the tail shaft is required to be fixed, the relative sliding phenomenon cannot occur in the operation process, the wear-resistant alloy internal sleeve and the tail shaft are in interference fit, the relative sliding phenomenon is likely to occur due to the vibration of equipment and other reasons in the operation process, the tail shaft is connected by a flat key, the phenomenon cannot occur, the tail shaft cannot be abraded, and the service life of the whole set of equipment is longer.
