Abstract
The invention relates to a bearing mounting tool with a centering function; the bearing mounting tool comprises a pressure head (1), a guide shaft (2) and a spring (3); the guide shaft (2) is installed inside the pressure head and is capable of moving axially inside the pressure head (1); the spring (3) is arranged at one end of the guide shaft (2); the other end of the spring (3) is pressed against the internal wall of the pressure head (1); the other end of the guide shaft (2) is capable of being stretched out of the end part of the pressure head (1); the external diameter of the part of the guide shaft (2) stretched out of the pressure head (1) is equal to the internal diameter of the hollow part of a shaft equipped with a bearing; and the internal diameter of the pressure head (1) matches with the external diameter clearance of the shaft to be mounted with the bearing. The centering function during installation is realized; no deflection of the bearing during installation is guaranteed and the requirement without damaging the bearing, the shaft and the bearing seat is satisfied.
Description
Technical field
The present invention relates to a kind of bearing installing tool, especially a kind of bearing installing tool with centering function, is arranged on hollow shaft for bearing by the mode of interference fit.
Background technology
Bearing in use, in order to ensure the reliability used, general bearing inner race and axle and installed by interference fit between outer ring and bearing block, therefore, just need very large pressure that bearing can be made to be in place in installation process.But be difficult to when pressure inner ring or outer ring ensure that the installation of bearing is without deflection, if there is deflection in installation process, will seriously injure bearing, axle and bearing block.Therefore, in installation process, make bearing correctly feel relieved, and ensure the correct very important of position of bearings.
Summary of the invention
The object of this invention is to provide a kind of bearing installing tool, described instrument has centering function, realizes bearing and installs without deflection, has advantages such as not injuring bearing, axle and bearing block.
Technical scheme of the present invention is: the erecting tools of bearing comprises pressure head, leading axle, spring, straight pin, and leading axle is arranged on pressure head inside, and can in the inner axially-movable of pressure head.Described leading axle one end is provided with spring, and the other end of spring is pressed on the inwall of pressure head.The other end of leading axle is from can the end of pressure head stretch out, and the external diameter stretching out the part of pressure head of leading axle is equal with the hollow internal diameter of bearings mounted axle, the internal diameter of pressure head with etc. the crest clearance of bearings mounted axle coordinate.Pressure head is also provided with symmetrical axial kidney-shaped groove, leading axle is provided with pin, described pin, from after leading axle stretches out, is positioned at the kidney slot that pressure head is arranged and also can moves along kidney slot.
During use, by bearing holder (housing, cover) on axle, if the magnitude of interference is too large, first can be heated by bearing, then leading axle is inserted axle endoporus, when pressure head lower end touches bearing inner race, forcing press acts on pressure head upper end, until bearing is in place.
The present invention by arranging leading axle in pressure head, and like this when pressure head is pressed onto bearing inner race, leading axle has been inserted in axle, realizes centering function.Simultaneously in order to ensure that leading axle only axially moves, a spring is set in the inner space of leading axle and pressure head.Being unlikely to allow leading axle exceed pressure head bottom and depart from pressure head, the range of movement of leading axle axis need be limited.Leading axle arranges a straight pin, and in both sides, pressure head relevant position, fluting can realize such function.Present invention achieves the function of first feeling relieved in installation process, ensure that bearing when mounted without deflection, achieve the requirement not injuring bearing, axle and bearing block in installation process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is operating diagram of the present invention.
Detailed description of the invention
As shown in the figure, the erecting tools of bearing comprises pressure head 1, leading axle 2, spring 3, straight pin 4, and it is inner that leading axle 2 is arranged on pressure head 1, and can in the inner axially-movable of pressure head 1.Described leading axle 2 one end is provided with spring 3, and the other end of spring 3 is pressed on the inwall of pressure head 1.The other end of leading axle 2 is from can the end of pressure head 1 stretch out, and the external diameter stretching out the part of pressure head 1 of leading axle 2 is equal with the hollow internal diameter of bearings mounted axle, the internal diameter of pressure head 1 with etc. the crest clearance of bearings mounted axle coordinate.Pressure head 1 is also provided with symmetrical axial kidney-shaped groove, leading axle 2 is provided with pin 4, described pin 4, from after leading axle 2 stretches out, is positioned at the kidney slot that pressure head 1 is arranged and also can moves along kidney slot.
