Problems solved by technology

[0003] In the engine, in order to prevent the oil in the cylinder block from leaking out, a crankshaft oil seal is installed on the crankshaft of the engine. When the direction of the fillet of the lip of the oil seal is opposite to that of the crankshaft, it has always been difficult to install and replace the crankshaft oil seal. The crankshaft oil seal installation tool in the technology usually uses a single guide sleeve to achieve guidance. This installation method will easily cause the lip of the oil seal to turn over, easily damage the oil seal, and reduce the success rate of oil seal assembly.

Embodiment Construction

[0025] figure 1 It is an assembly schematic diagram of the oil-sealed crankshaft of the present invention, figure 2 It is a schematic diagram of the pressing sleeve of the present invention, image 3 It is a schematic diagram of the positioning sleeve of the present invention. As shown in the figure, an anti-oil seal flip installation tool includes a press-in sleeve 3, a positioning sleeve 4 for positioning the oil seal 2, and a positioning sleeve 4 for guiding and assembling the oil seal 2 to the positioning sleeve 4. The guide sleeve 5 and the positioning sleeve 4 are arranged at the end of the crankshaft 1, and the press-in sleeve 3 can press-fit the oil seal 2 to the crankshaft 1 along the axial direction of the positioning sleeve 4. Through the press-in sleeve 3, positioning sleeve 4, and guide sleeve 5 in this technical solution, the oil seal can be easily and quickly assembled on the crankshaft 1, and at the same time, it is ensured that the lip of the oil seal 2 will...

Abstract

The invention discloses an oil seal overturning preventive mounting tool and an assembling method. The oil seal overturning preventive mounting tool comprises a press-in sleeve, a positioning sleeve for positioning an oil seal, and a guide sleeve for guiding and assembling the oil seal to the positioning sleeve, wherein the positioning sleeve is arranged at the end part of a crankshaft; and the oil seal can be mounted to the crankshaft in a press fitting manner through the press-in sleeve in the axial direction of the positioning sleeve. According to the technical scheme, the assembling tool improves the assembling efficiency; an oil seal lip port of the oil seal in assembling process cannot be negatively rotated to be damaged, and thus the product assembling quality can be ensured.

Description

technical field [0001] The invention relates to the field of mechanical assembly, in particular to an oil seal flip-proof installation tool and an assembly method. Background technique [0002] Oil seal (oil seal) is the customary title of general seals, simply put, it is the seal of lubricating oil. It is a mechanical element used to seal grease (oil is the most common liquid substance in the transmission system, and it also generally refers to the general liquid substance). Oil leaks. Seals for static seals and dynamic seals (general reciprocating motion) are called oil seals. [0003] In the engine, in order to prevent the oil in the cylinder from leaking out, a crankshaft oil seal is installed on the crankshaft of the engine. When the direction of the rounded corner of the oil seal lip is opposite to that of the crankshaft, it has always been difficult to install and replace the crankshaft oil seal. The crankshaft oil seal installation tool in the art usually uses a s...
