An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a structural design reasonable, sealed effectual, have cushioning effect's lifting machine tail-shaft seal structure.

The utility model provides a technical scheme that above-mentioned problem adopted is: the utility model provides a lifting machine tail-shaft seal structure, sets up the through-hole that supplies the tail-shaft both ends to wear out at the relative both sides face of lifting machine casing to all be provided with closing plate and mount pad, its characterized in that in the outside of this both sides face: the sealing plate is tightly attached to the side face of the shell of the lifting machine and sleeved on the tail shaft, and a sealing ring is arranged between the sealing plate and the tail shaft; the end part of the tail shaft is provided with a bearing seat, the bearing seat is fixedly connected with the mounting seat, a bearing is arranged in the bearing seat, the bearing sleeve is arranged at the end part of the tail shaft, the end part of the bearing seat is provided with a bearing end cover used for positioning an outer ring of the bearing, the bearing end cover is connected with the bearing seat through a buffer fastener, the buffer fastener comprises a bolt and a buffer spring, and the bearing seat is connected with the bearing end cover through the bolt; the buffer spring is sleeved on the bolt and is positioned between the bearing seat and the bearing end cover.

Preferably, the bearing frame seals through the oil blanket with the tailshaft.

Preferably, the bearing end cover of the utility model is provided with an oil inlet,

preferably, the buffering fastener sets up six, along bearing end cover circumference equipartition

Compared with the prior art, the utility model, have following advantage and effect: the tail shaft and the sealing plate are sealed, and the sealing plate prevents dust in the elevator shell from overflowing outwards; the bearing end cover is connected with the bearing seat through the buffering fastener, so that the tail shaft can be prevented from axially moving in a small range, and the effect of buffering and absorbing vibration is achieved on the tail shaft.

Drawings

In order to illustrate the embodiments of the present invention or the solutions in the prior art more clearly, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without creative efforts.

Fig. 1 is a schematic diagram of a half-section structure of an embodiment of the present invention.

Fig. 2 is an enlarged schematic view of a portion a in fig. 1.

Description of reference numerals: the lifting machine comprises a lifting machine shell 1, a sealing plate 2, a mounting seat 3, a buffer spring 4, a bolt 5, a bearing end cover 6, an oil inlet 7, a bearing 8, a sealing ring 9, a tail shaft 10, a bearing seat 11 and an oil seal 12.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

See fig. 1-2.

This embodiment is a lifting machine tail-shaft seal structure, sets up the through-hole that supplies tail-shaft 10 both ends to wear out at the relative both sides face of lifting machine casing 1 to all be provided with closing plate 2 and mount pad 3 in the outside of this both sides face, closing plate 2 hugs closely lifting machine casing 1 side, and overlaps on tail-shaft 10, is provided with sealing washer 9 between closing plate 2 and the tail-shaft 10, and closing plate 2 plays and prevents that the dust in the lifting machine casing 1 from outwards bubbling out.

In this embodiment, bearing frame 11 is installed to the tip of tail-shaft 10, and bearing frame 11 and mount pad 3 fixed connection install bearing 8 in the bearing frame 11, and 8 covers of bearing are established and are installed at the 10 tip of tail-shaft, and 11 tip installations of bearing frame are used for carrying out bearing cap 6 of fixing a position to the 8 outer lanes of bearing, and bearing cap 6 links together through buffering fastener and bearing frame 11, and buffering fastener sets up six, along 6 circumference equipartitions of bearing cap.
