Description

Dustproof structure of elevator

Technical Field

The utility model relates to a lifting machine, in particular to lifting machine dustproof construction.

Background

When the hoister is used for transporting in a cement plant, because the bearings are arranged at two sides of the rotating shaft in the machine body, because the mounting hole of the driving shaft has a gap, and the main shaft has circular run-out during operation, the gap is larger and larger, a large amount of dust is easy to enter, the abrasion is aggravated, and the service life of the shaft and the bearings is influenced; and is liable to generate loud noise.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lifting machine dustproof construction to the dust that advances that proposes in solving above-mentioned background art leads to wearing and tearing to aggravate the problem.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a lifting machine dustproof construction, which comprises a bod, there is the driving shaft organism lower part, the cover has the bearing on the driving shaft left part, a serial communication port, it has the axle sleeve cover on the driving shaft to be located driving shaft mounting hole department, the axle sleeve is by cylinder and toper boss integrated into one piece, integrated into one piece has circular baffle on the cylinder, the axle sleeve middle part is the through-hole, the through-hole left part has the cone angle, circular baffle is fixed on the organism, there is cloth on the axle sleeve, the driving shaft right-hand member passes the bearing frame and passes through flange and motor connection, motor.

Further, the taper angle is the same as the taper of the tapered boss.

Further, the cloth is wound or bonded on the shaft sleeve.

Compared with the prior art, the beneficial effects of the utility model are that: prolong equipment live time after dustproof, noise abatement.

Detailed Description

The technology in the embodiment of the present invention will be described below with reference to the accompanying drawings in the embodiment of the present invention

The embodiments are described in detail, clearly, and not in their entirety, it is to be understood that the embodiments described are only some of the embodiments of the present invention and are not to be taken as a complete description. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

In fig. 1 and 3, a dustproof structure of a hoist, including a machine body 1, a driving shaft 2 is arranged at the lower part of the machine body 1, a bearing 3 is sleeved on the left part of the driving shaft 2, and the dustproof structure is characterized in that a shaft sleeve 4 is arranged at the mounting hole of the driving shaft 2 and sleeved on the driving shaft 2, the shaft sleeve 4 is formed by a cylinder 4.1 and a conical boss 4.2 in an integrated manner, a circular baffle 4.4 is formed on the cylinder 4.1 in an integrated manner, a through hole 4.3 is formed in the middle part of the shaft sleeve 4, a conical angle is inverted at the left part of the through hole 4.3, the circular baffle 4.4 is fixed on the machine body 1, cloth 7 is arranged on the shaft sleeve 4, the right end of the driving shaft 2 penetrates through a bearing seat 9 and.

Further, the taper angle is the same as the taper of the tapered boss 4.2.

Further, the cloth 7 is wound or bonded on the sleeve 4.

When the water-saving device is used, only the shaft sleeve 4 is required to be installed on the machine body 1, the bearing is led out of the machine body 1, then the circular baffle 4.4 and the cloth 7 are sealed, water can be poured on the cloth 7, and the installation of the driving shaft 2 is facilitated by the arrangement of the through hole 4.3.

In the present invention, unless otherwise explicitly specified or limited, for example, it may be fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate medium, and may be connected through the inside of two elements or in an interaction relationship between two elements, unless otherwise specifically defined, and the specific meaning of the above terms in the present invention will be understood by those skilled in the art according to specific situations.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
