Description
Technical field
The utility model relates to the assembly tool field, is specifically related to a kind of bearing press mounting frock.
Background technology
In the group of motors process of assembling, the mounting process of bearing plays most important to the performance quality of motor.The rotation of motor relies on bearing to rotate.For high-speed electric expreess locomotive, the function influence of bearing is huge.The rotation of traditional bearing should be satisfied quiet requirement and will guarantee and can not damage at the situation lower bearing that continues high speed rotating.
When bearing is installed in the prior art adopt following three kinds of modes: 1, manually weigh mode more: first bearing is installed on the turning cylinder, recycling glue hammer or wood beat with about the mode of knocking up and down bearing is struck default position to the turning cylinder.This turning cylinder is the installing of fitted bearing, all can be in its openend appropriate location.Shortened its service life; And this mode only can be applied to the bearing of reduced size.2, utilize the mode of expanding with heat and contract with cold that bearing is installed, i.e. utilization heating bearing makes its diameter become large and can be placed in the axle spare easily.But this mode practicality is poorer and more inconvenient, and the bearing after reason is to heat produces easily distortion and has influence on itself structure, and heating-up temperature is quite high, and is very inconvenient during assembling.3, utilize the oil pressure bed that bearing is installed: utilize the oil pressure bed install bearing oneself through being very inconvenient, still more also to some extent restriction of the length of oil pressure bed, therefore the bearing of specific dimensions only can be installed, more do not possess generality, and the expense of special-purpose machinery is not low yet, is very uneconomic to major part with the facility of bearing.
In order to guarantee that bearing installation accurate positioning protection bearing is not damaged so will design a kind of specific purpose tool to meet the needs of production.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of bearing press mounting frock, its objective is, provide a kind of reasonable in design, simple in structure, and low cost of manufacture is easy and simple to handle, guarantee during installation the bearing accurate positioning to be difficult for causing damage of bearings during installation.
For achieving the above object, the technical solution of the utility model is as follows:
The bearing press mounting frock, it comprises rotor, described rotor is penetrated with the rolling ladder axle, described rolling ladder axle upper end is provided with handler, handler is socketed among the sleeve, be provided with upper bearing (metal) between the step of described sleeve lower plane and rolling ladder axle upper end, be socketed with positioning sleeve outside the upper bearing (metal), described lower cartridge places among the positioning sleeve; Described rolling ladder axle is provided with the first ladder, the second ladder and the 3rd ladder, the first ladder is provided with lower bearing with the step that the second ladder is connected, lower bearing is connected with drive end bearing bracket outward, the below of described lower bearing is provided with the bucket seat, the lower end of described rolling ladder axle places among the bucket seat, upper plane inboard formation flange and the lower bearing clamping of described drive end bearing bracket, drive end bearing bracket lower plane form the outstanding and bucket outer rim clamping of annular.
Preferably, the lower plane that the lower plane of bearing is higher than the second ladder forms the gap, and the upper plane of described bucket seat forms step flange, step flange and described lower bearing lower plane fit tightly and and the second ladder between form the gap.
By technique scheme, the beneficial effect that the utility model is obtained is, is provided with the ladder turning cylinder among the bucket seat, and the upper surface of ladder turning cylinder is provided with handler, and handler is socketed in the sleeve, and handler is connected with the output shaft of the motor of outside.Driven by motor ladder turning cylinder rotates, and described ladder turning cylinder all is installed on up and down rolling bearing, and smooth rotation when guaranteeing pressing bearing is so that the actuating pressure to bearing steadily evenly prevents the bearing secundly when pressing bearing.It is a kind of reasonable in design that the utility model provides, structure is comparatively simple, manufacturing cost is lower, easy and simple to handle, be difficult for causing the last item of damage of bearings to hold frock during installation, and improved the installation accuracy of bearing, solved the problem that existing bearing mounting means might cause damage of bearings, it is comparatively complicated also to have solved simultaneously existing bearing installer structure, and manufacturing cost is higher, the problems such as operation inconvenience.
