Embodiment

[0023] Embodiment: a kind of adjustable eccentric sleeve, such as figure 1 , figure 2 shown. Such as figure 1 As shown, the device includes a vertically placed collar 1 with a round hole in the center. Adjusting blocks 2 are respectively provided on the outer walls of the upper, lower, left, and right sides of the collar 1. Both are plane, and there is a copper gasket 3 sandwiched between the inner side of the adjustment block 2 and the outer side of the collar 1, and the gasket 3 has a variety of specifications with different thicknesses for replacement. The outer surface of the adjustment block 2 is an arc surface, and the arc is matched with the aperture of the eccentric sleeve installation, so that the outer surface of the adjustment block 2 can be closely matched with the hole wall of the installation place, and has enough contact surface. The outer surface of the adjustment block 2 protrudes from the circumference of the maximum outer diameter of the collar 1. When a...

Abstract

The present invention relates to an adjustable eccentric sleeve which can be adjusted according to eccentricity, and solves problems of an existing eccentric sleeve, such as narrow adaptability and incapability to meet the accommodation of different eccentric errors. The device comprises a lantern ring with a round hole in the middle, which is characterized in that a circumferential outer wall of the lantern ring is uniformly provided with at least three regulating blocks; the regulating blocks are fixed with the lantern ring through adjusting screws; and a detachable and replaceable gasket is arranged between each regulating block and the outer wall of the lantern ring. The invention adopts a form of detachable gasket to realize an adjustable structure of the eccentric sleeve, so as to meet adjusting demands of different eccentric errors; and during the adjustment process, the eccentric sleeve and a mounting hole maintain adequate contact surface to ensure the strength of support.

Description

technical field [0001] The invention relates to an eccentric sleeve, in particular to an adjustable eccentric sleeve which can be adjusted according to the amount of eccentricity. technical background [0002] In the manufacture of mechanical equipment, due to the influence of the machining accuracy and assembly accuracy of mechanical parts, the product often cannot meet the original design requirements, resulting in eccentricity errors in the axial direction of the product and affecting the operation of the equipment. Generally, an eccentric sleeve is installed on the outer bearing , to correct the eccentric error, so that the equipment can operate normally, and conversely, the application of the eccentric sleeve to correct the deviation also reduces the processing accuracy requirements of some equipment. However, since the eccentricity, eccentric angle and other errors of each device, or even different positions of the same device, are different, the same type of eccentric...
