Mounting tool for mounting bearing of shaft head of motor

Abstract

The invention provides a mounting tool for mounting a bearing of a shaft head of a motor. A vertical column (1) of the mounting tool has a circular rod structure; one end of the vertical column (1) is connected with a shaft head end (5) of a motor shaft head (14) through a bolt (4); a pushing sleeve (2) has a hollow structure; the pushing sleeve (2) is screwed with a thread tooth part at the other end of the vertical column (1) through a thread part distributed on an inner cavity of the pushing sleeve (2); and a handle (3) is connected with the pushing sleeve (2). Under the condition that the bearing cannot be mounted according to a hot sleeve method, the mounting tool for mounting the bearing of the shaft head of the motor provided by the invention can be used for cold-pressing the bearing through a manual mounting tool and quickly and conveniently mounting the bearing on the shaft head of the motor. Meanwhile, by using the mounting tool provided by the invention, the interior structures of the bearing and the motor are not damaged by knocking inner and outer rings, so that the mounting tool is portable and convenient, the assembling efficiency is increased and the bearing and the bearing and encoder in the motor are effectively prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of installing motor shaft head accessories, and more specifically relates to an installation tool for installing motor shaft head bearings. Background technique [0002] The motor shaft head is used to connect gears, pulleys, couplings, bearings and other parts. Some connections are loose and easy to install, while some connections are tighter, such as bearings. The fit between the inner ring of the bearing and the shaft head is generally an interference fit. The common assembly methods include shrink fit, cold pressing, knocking on the inner ring and knocking on the outer ring. Among them, the shrink fit is the most ideal, but it is only suitable for unsealed bearings. For bearings with sealing rings, the sealing rings will be burned out when heated, and hitting the inner and outer rings will not only damage the bearings, but also damage the internal structure of the motor, so it can only be installed by co...

The fit between the inner ring of the bearing and the shaft head is generally an interference fit. The common assembly methods include shrink fit, cold pressing, knocking on the inner ring and knocking on the outer ring. Among them, shrink fit is the most ideal, but it is only suitable for non-sealed bearings. For bearings with sealing rings, the sealing rings will be burned out when heated, and hitting the inner and outer rings will not only damage the bearings, but also damage the internal structure of the motor, so it can only be installed by cold pressing
