Description
Technical field
The utility model relates to a kind of Simple detachable device of the conveying screw rod for extruder.Belong to mechanical device technical field.
Background technology
Existing for the conveying screw rod on extruder (particularly Rubber Extruder), length is generally 2-4 rice, and be arranged in extruder, one end of screw rod is connected with decelerator, and the other end is connected with running part.Conveying screw rod often needs inspection and maintenance, the one end be connected with running part is due to limited space, screw rod removes forward very inconvenience, when therefore safeguarding, relatively more convenient pulls down the one end be connected with decelerator, then exits backward, and decelerator must remove by conventional method for dismounting, meeting like this increases the workload of workman greatly, and dismantles very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of Simple detachable device of conveying screw rod, when needs dismounting conveying screw rod, only need turn on trapezoidal cover, then axial positioning sleeve be exited, finally screw rod is exited, quick and convenient, decrease the workload of workman.
The purpose of this utility model is achieved in that
A kind of Simple detachable device of conveying screw rod, be characterized in: described device is arranged in output shaft, described device comprises trapezoidal cover, axial positioning sleeve and thrust bearing, axially through hole is provided with in described output shaft, described axial location is set in this through hole, be connected with the inner thread of output shaft left end in the left end through hole that trapezoidal cover protruding end embeds output shaft, the protruding end of trapezoidal cover and the left end of axial positioning sleeve offset, and offset in the through hole that the left end of screw body stretches into output shaft with the right-hand member of axial positioning sleeve.
The Simple detachable device of a kind of conveying screw rod of the utility model, output shaft is arranged on casing, is provided with thrust bearing between casing and output shaft.
The Simple detachable device of a kind of conveying screw rod of the utility model, the left end of its screw body has screw hole.
Compared with prior art, the beneficial effects of the utility model are:
1. the Simple detachable device of a kind of conveying screw rod of the utility model, during dismounting, only need turn on trapezoidal cover, then be exited by axial positioning sleeve, finally exited by screw rod, quick and convenient, decreases the workload of workman.
2. the Simple detachable device of a kind of conveying screw rod of the utility model, the back pressure that screw body produces is delivered to output shaft by axial positioning sleeve and trapezoidal cover, is finally born by thrust bearing, the good stability of therefore equipment operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Simple detachable device of a kind of conveying screw rod of the utility model.
Fig. 2 is the structural representation of screw body of the present utility model.
In figure:
Trapezoidal cover 1,
Axial positioning sleeve 2,
Output shaft 3,
Screw body 4,
Screw hole 4.1,
Thrust bearing 5,
Casing 6.
Detailed description of the invention
See Fig. 1, the utility model relates to a kind of Simple detachable device of conveying screw rod, it comprises trapezoidal cover 1, axial positioning sleeve 2 and thrust bearing 5, output shaft 3 is arranged in casing 6, thrust bearing 5 is provided with between casing 6 and output shaft 3, thrust bearing 5 is for bearing the thrust brought when screw body 4 works, axially through hole is provided with in described output shaft 3, described axial positioning sleeve 2 is arranged in this through hole, trapezoidal cover 1 protruding end embeds with the left end of output shaft 3 and is threaded with it, the protruding end of trapezoidal cover 1 and the left end of axial positioning sleeve 2 offset, offset with the right-hand member of axial positioning sleeve 2 in the through hole that the left end of screw body 4 stretches into output shaft 3.
See Fig. 2, the left end of described screw body 4 has screw hole 4.1.
During work, the back pressure that screw body 4 produces is delivered to output shaft 3 by axial positioning sleeve 2 and trapezoidal cover 1, is finally born by thrust bearing 5, therefore can not affect the stability that equipment runs.
Dismounting mode: during dismounting, first turns on trapezoidal cover 1 and exits, then exiting axial positioning sleeve 2, then with adding long spiro nail and be screwed into the screw hole 4.1 of screw body 4 left end, pull out long spiro nail thus exit screw body 4, unloading process is quick and convenient.
