Embodiment Construction

[0028] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.

[0029] refer to Figure 1-4 , the assembly tool of a kind of engine flywheel bearing of the present invention comprises the beating body 1 that is used for positioning and beating bearing 2, and the end face of this beating body 1 is circular, is provided with bearing 2 on one end face of this beating body 1 The flat cylindrical reference boss 3 whose outer ring size is suitable, one end face of its bearing 2 is in contact with the end face of the reference boss 3, and a height difference between the beating body 1 and the reference boss 3 forms a preventable The ring-shaped relief groove 4 where the beating body 1 interferes with the side wall of the bearing installation hole. During the installation of the bearing 2, when one end of the bearing 2 is parallel to the end face of the bearing installation hole, the bearing 2 continues to be in...

Abstract

The invention discloses an assembly tool for an engine flywheel bearing, which includes a knocking body used for positioning and hitting the bearing. One end surface of the knocking body is provided with a flat cylindrical reference boss matching the size of the outer ring of the bearing. The height difference between the outer edge of the end surface of the beating body and the reference boss forms an annular relief groove that can prevent the beating body from interfering with the side wall of the bearing installation hole. The reference boss is also arranged coaxially with it and can be The cylindrical positioning boss that is movably inserted into the inner ring of the bearing is provided with an annular groove that is axially concave along the outer edge of the positioning boss on the reference boss near the side of the positioning boss. A plurality of magnetic rods are evenly distributed in the annular groove of the ring and are inserted axially into the knocking body from the bottom thereof. The invention also discloses an assembly method of the engine flywheel bearing. The invention has simple structure and convenient operation, realizes quick assembly of the bearing of the flywheel of the engine, and solves the problem of low assembly efficiency of the bearing.

Description

technical field [0001] The invention relates to the technical field of engine assembly, more specifically, it relates to an assembly tool and an assembly method of an engine flywheel bearing. Background technique [0002] In the engine (diesel engine) manufacturing industry, the assembly of engine parts will directly affect the performance and quality of the whole machine. During the engine assembly process, some parts need to be assembled on the body in the form of interference fit, especially for Assembly of bearings. At present, for the bearing assembly of the engine flywheel, it is usually first to take the bearing by hand or put the bearing on a tooling by hand, then beat the bearing or the tooling by hand, and finally assemble the bearing in place. Such an assembly method has high labor intensity and low assembly efficiency, and also has potential safety hazards. Therefore, a simple and labor-saving bearing assembly method becomes particularly important. Contents o...
