Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor, particularly a kind of grinding head motor.
Background technology
Grinding head motor is also known as high-speed grinding head motor, because its excellent performance is widely used in the fields such as metal material grinding, glass material, ceramic material at present.At present, the rotating shaft of existing grinding head motor is that entry type is set on motor front and back ends by bearing, by wave washer elastic force make rotating shaft axially wherein one section spacing, grinding head motor due to processing environment comparatively severe, when the cutting force of emery wheel is greater than wave washer elastic force, there will be the forward and backward movement of rotating shaft out of control, occur axial endplay, Long-Time Service there will be the phenomenons such as diastema, cannot meet high-precision grinding needs.
For above-mentioned Problems existing, people have made improvement miscellaneous to grinding head motor, and some has also applied for patent, such as, disclose a kind of grinding head motor structure [application number: 201220145131.5 eliminating axial endplay in Chinese patent literature data; Authorization Notice No.: CN202550770U], it comprises motor body, motor body end is provided with end cap, bearing chamber is provided with in end cap, be provided with bearing in bearing chamber, be provided with axis through bore in bearing chamber, axis through bore inwall is provided with internal thread, axis, by the interior positioning sleeve be also provided with for compressing bearing, has the external screw thread with the internal thread corresponding matching of axis through bore outside this positioning sleeve.
Above-mentioned a kind of grinding head motor structure eliminating axial endplay, be connected with the axis through bore inner thread in bearing chamber by positioning sleeve, by regulating positioning sleeve to locate epitrochanterian bearing outer ring, compare the phenomenon that traditional technology solves rotating shaft axial endplay to a certain extent.But its structure need process internal and external threads, its difficulty of processing is increased, cost improves, and its motor other end does not arrange location structure, causes its other end in harsh environments, occur the phenomenons such as rotating shaft vibration.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of structure simple, eliminates the grinding head motor of axial endplay.
The purpose of this utility model realizes by following technical proposal: a kind of grinding head motor, comprise motor shaft, motor casing and the front end housing and the rear end cap that are installed on motor casing rear and front end, described motor shaft is arranged in motor casing, described motor shaft is connected by fore bearing with front end housing, described motor shaft is connected by rear bearing with rear end cap, the rear end of described motor shaft is arranged with fan blade, it is characterized in that, the inner side of described front end housing is fixed with pressing plate by screw, described pressing plate has the flange part that a circle is resisted against fore bearing outer ring, the inner side of described rear end cap has the boss that a circle is resisted against rear bearing outer ring.
This grinding head motor, compress fore bearing outer ring by pressing plate, by the outer ring of the boss location rear bearing inside rear end cap, its structure is not only simple, and effectively can eliminate the axial endplay of motor shaft and bearing, thus ensure that the steady operation of grinding head motor and extend its useful life.
In above-mentioned a kind of grinding head motor, between described screw and pressing plate, be provided with lock washer.
In above-mentioned a kind of grinding head motor, described motor shaft stretches out outside front end housing, is arranged with outside framework oil seal between described motor shaft and front end housing.Arranging of outside framework oil seal can enter motor internal by anti-sealing.
Compared with prior art, this grinding head motor structure is simple, can eliminate the advantage of axial endplay.
