Description

Large-scale breaker rotor of high strength that can alternate use

Technical Field

The utility model relates to large-scale crusher equipment, in particular to a large-scale crusher core component rotor.

Background

The large-scale crusher is generally used for crushing materials in industries such as mines, chemical engineering, building materials and the like, and for the large-scale crusher, the crushed materials are directly conveyed into a cavity of the large-scale crusher through a feed inlet, and then the materials entering the cavity of the large-scale crusher are crushed through a hammer head arranged on a rotor of the large-scale crusher, so that the purpose of crushing the materials is achieved. However, as the working time of the large crusher is prolonged, the hammer holes arranged on the hammer disc of the rotor of the large crusher are deformed or cracked due to large impact, the concentricity of the hammer shaft is damaged, the dynamic balance of the rotor is damaged when the rotor works, the crusher vibrates, the normal work of the bearing on the rotor of the crusher is influenced, and the damage of the bearing is aggravated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a high-strength large crusher rotor capable of being used alternately, wherein a set of spare hammer holes are added on a hammer disc of an original crusher rotor, the original set of rotor hammer disc can be used twice, and the service life of the rotor hammer disc is prolonged by one time. Thereby improving the utilization ratio of the rotor hammer disc, prolonging the service life of the rotor and reducing the operation cost of the large-scale crusher for crushing materials.

The purpose of the utility model is realized by the following technical scheme:

the utility model provides a large-scale breaker rotor of high strength that can alternate use, includes the main shaft, installs the hammer disks on the main shaft, sets up the hammer hole on the hammer disks, the hammer hole includes work hammer hole and reserve hammer hole, and the work hammer hole is at least three, still is provided with reserve hammer hole between adjacent work hammer hole.

The hammer shaft penetrates through the hammer hole of the high-strength large crusher rotor which can be alternately used.

The hammer shaft sleeve is arranged between the hammer hole and the hammer shaft.

In the alternatively-used high-strength large crusher rotor, the hammer shaft sleeve is made of 35 CrMo.

The number of the working hammer holes is four, the four working hammer holes are uniformly distributed on the hammer disc, the number of the corresponding standby hammer holes is four, and the working hammer holes and the standby hammer holes are arranged on the hammer disc in a staggered mode.

The main shaft of the high-strength large crusher rotor which can be alternately used is provided with a main shaft key, and the main shaft is connected with the hammer disc through the main shaft key.

By adopting the technical scheme, the utility model has the following beneficial technical effects:

1. when the rotor of the large crusher is produced and manufactured, on the basis of n working hammer holes which are originally distributed and arranged in n degrees on a rotor hammer disc, the rotor hammer disc respectively rotates to the middle of two adjacent working hammer holes along the clockwise direction or the anticlockwise direction, and then n hammer holes are manufactured and used as spare hammer holes.

2. Each hammer hole is reinforced by a hammer shaft sleeve, the hammer shaft sleeve is produced by adopting a 35CrMo material, and the service life of the hammer shaft hole is prolonged by carrying out the process treatment of toughness and wear resistance through quenching and tempering and surface quenching in the hammer shaft sleeve.

3. When a set of hammer shaft holes on a rotor hammer disk of a large crusher are deformed or cracked and cannot be used for a long time, the cracked hammer shaft holes are repaired, and then the set of hammer shaft holes are not used. But rather uses another set of alternate hammer shaft holes so that the rotor can operate. When the two sets of hammer shaft holes can not be used any more, the rotor hammer disks are updated.

The utility model has the advantages that in the process of crushing materials by the large-scale crusher, the original set of rotor hammer disk can be used twice, which is equivalent to the service life of the rotor hammer disk is doubled. Thereby improving the utilization ratio of the rotor hammer disc, prolonging the service life of the rotor and reducing the operation cost of the large-scale crusher for crushing materials.

Detailed Description

The structure and operation of the present invention will be described in detail with reference to fig. 2 and 3.

In the description of the present invention, it is to be understood that the terms "central," "radial," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing and simplifying the description, and do not indicate or imply that the device or component in question must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore should not be considered as limiting.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The rotor is a core part of a large-sized crusher, and the rotor rotates to drive a hammer head arranged on the rotor to rotate at a high speed so as to crush materials entering a cavity of the crusher. Referring to fig. 2 and 3, the present invention provides a high strength large crusher rotor which can be used alternatively, comprising a main shaft 3, wherein the main shaft is the main supporting part of the rotor, is connected with a motor belt pulley, and is driven to rotate by a motor. The hammer disk 2 is arranged on the main shaft and is a hammer head supporting disk uniformly distributed on the main shaft. The hammer disk is provided with hammer holes 5, and the hammer holes are hammer shaft supporting holes uniformly distributed on the hammer disk.
