Heating ring with diameter capable of being adjusted in fine mode

Abstract

The invention discloses a heating ring with the diameter capable of being adjusted in a fine mode. The heating ring comprises a heating ring body, wherein the heating ring body is provided with an opening seam, the outer peripheral surface of the heating ring body is provided with expansion joints consistent with the axial width of the heating ring body, the expansion joints are evenly distributed along the two radial sides of the opening seam, anti-crack holes are formed in the roots of the expansion joints, and heating ring diameter fine adjustment devices are arranged on the parts, at two radial sides of the opening seam, of the heating ring body. According to the heating ring with the diameter capable of being adjusted in the fine mode, the inner diameter of the heating ring changes evenly, the diameter of the heating ring is accurately controlled, the heating ring can be operated in a narrow operation space, and repairing efficiency and repairing accuracy are improved.

Description

technical field [0001] The invention relates to a heating ring whose diameter can be finely adjusted. Background technique [0002] At present, the existing (such as SKF) heating rings on the market also have adjustable diameter forms in their design. However, the adjustment of the existing adjustable diameter heating rings on the market is to use multiple handles to control the variation of the heating ring diameter, and the adjustment of the pretightening force depends on the strength of the operator's hands to hold the long handles tightly. There are many and the space required for operation is large, which is not conducive to operation. The expansion joints of existing heating rings on the market do not have a limit device and a crack relief hole design, which may easily cause the heating ring to fail to form a perfect circle and crack at the root of the expansion joint. Contents of the invention [0003] The technical problem to be solved by the present invention is...
