Abstract
The utility model provides an eccentric block for a vibration exciter. When the eccentric block is disassembled or assembled, auxiliary equipment is not needed, the operation is simple and convenient, and the structure is simple. The eccentric block comprises a shaft hole and at least one eccentric hole. One end of the eccentric block, which is near the shaft hole, is provided with a wide slot which is adaptive with the shaft hole; the inner diameter of the shaft hole is greater than the outer diameter of an assembled shaft; and the wide slot is provided with a locking device used for locking the assembled shaft in the shaft hole. The eccentric block and the shaft are designed to be in large clearance fit, thereby, the disassembling and the assembling are simple, the maintenance is convenient, and auxiliary equipment or tools, such as large-sized press machines or cold chargers or hot chargers, are not needed.
Description
Technical field
The utility model provides a kind of vibrator to use eccentric block.
Background technology
Eccentric block is the main source that vibrator produces exciting force; Have that volume is big, quality heavily waits characteristics, traditional eccentric block is an interference fit with the fit system of axle, and is low to guarantee stable working, noise; But during dismounting; Need to be pressed into or to adopt cold charge or hot-mounting process with the large pressing machine tool, complicated operation, optional equipment is many.
Summary of the invention
In order to overcome the problem that exists in the background technology, the utility model provides a kind of vibrator to use eccentric block, and this eccentric block need not optional equipment when dismounting, easy and simple to handle and simple in structure.
The concrete technical solution of the utility model is following:
This vibrator is used eccentric block, comprises axis hole and at least one eccentric orfice, and eccentric block is provided with the sipes suitable with axis hole near axis hole one end, and shaft hole diameter is greater than the external diameter of assembled shaft; Said sipes is provided with the locking device that is used to lock the axle of assembling in the axis hole.
It between above-mentioned axis hole and the assembled shaft big matched in clearance.
Above-mentioned locking device is that bolt links pair, and said bolt links pair and comprises lock washer, locking nut and bolt; Eccentric block is provided with the bolt hole that is used for assembling bolt.
The width of above-mentioned sipes is 6mm, and bolt is 10.9 grade bolts.
The advantage of the utility model is following:
Eccentric block is big matched in clearance with the matching design of axle, and dismounting is simple to operate, and is easy to maintenance, need not large pressing machine or auxiliary equipment or frocks such as cold charge or hot charging.
Description of drawings
Fig. 1 is the utility model structural representation.
Accompanying drawing is detailed as follows: the 1-eccentric block; The 2-bolt; The 3-lock washer; The 4-locking nut.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is detailed:
This eccentric block comprises axis hole and at least one eccentric orfice, is generally 5, and eccentric block is provided with the sipes suitable with axis hole near axis hole one end, and width is generally 6mm, and the number of eccentric orfice and the width of sipes can be adjusted according to actual conditions; Shaft hole diameter is generally big matched in clearance greater than the external diameter of assembled shaft; Sipes is provided with the locking device that is used to lock the axle of assembling in the axis hole, and it is secondary generally to adopt bolt to link, and bolt links pair and comprises two lock washers, a locking nut and a bolt; Eccentric block is provided with the bolt hole that is used for assembling bolt.
During installation, at first, sling eccentric block with driving, carry out and an axle centering, centering is accomplished the back and is rapped the entering installation shaft with iron hammer, and construction bolt links secondaryly on eccentric block then, and bolt links pair and is made up of 2 lock washers, 1 locking nut and 10.9 grade bolts; Under powerful Bolt Tightening Force square, eccentric block can produce the big displacement on the screwing force direction, from making the displacement of generation in the radial direction of axis hole, reaches the purpose of lock shaft; When tearing eccentric block open, link pair as long as unclamp bolt, do not have under the extruding force, eccentric block will recover original form, and axle just reaches design load with the gap in eccentric block hole, under the help of driving, easily accomplishes dismounting.
This vibrator is used eccentric block, when having solved existing eccentric block dismounting, needs be pressed into or adopt cold charge or hot-mounting process with the large pressing machine tool complicated operation, the problem that optional equipment is many.
