A reducer oil seal installation tool

Abstract

The invention provides a mounting tool for an oil seal of a reduction gear. The mounting tool comprises a tool body, wherein the inside through hole of the tool body is divided into three-segment round holes which are coaxial, namely a primary mounting segment, an intermediate segment and a post-mounting segment; the diameters of the primary mounting segment and the post-mounting segments are equal to that of a large-diameter segment of a stepped shaft; the diameter of the intermediate segment is equal to that of a small-diameter segment of the stepped shaft; a lug boss is arranged on the outer side of the primary mounting segment; a groove is formed in the outer side of the post-mounting segment; the depth of the groove is equal to the distance between the outer end surface of the oil seal outside and the outer side surface of an end cover; the length of the post-mounting segment is larger than the distance between the interface of the large-diameter segment and the small-diameter segment of the stepped shaft and the outer side surface of the end cover; and the diameter of the groove is larger than that of the oil seal. When the mounting tool is used for mounting, the oil seal is fixed on the stepped shaft and can be very conveniently and quickly mounted in a pre-determined position which is a pre-determined distance away from a sealing surface by use of the mounting tool of which the size is well designed in advance.

Description

technical field [0001] The invention relates to the technical field of gear reducer oil seal installation, in particular to a gear reducer oil seal installation tool. Background technique [0002] When the reducer is running, the function of the oil seal is to seal the oil and prevent foreign matter (dust, etc.) from entering the reducer. When the reducer is equipped with an oil seal, the oil seal is generally set on the large diameter section of the stepped shaft 7 protruding from the end cover 6 of the reducer, such as figure 1 As shown, in order to enhance the effect of the oil seal, sometimes two oil seals are provided. The position of the oil seal 4 has strict requirements. One oil seal 4 is located inside the end cover 6 and the other is located outside the end cover 6 . The existing oil seal installation technology is generally to put the oil seal 4 on the stepped shaft 7, manually smash the oil seal 4 to the desired position, and manually measure the position of the...
