Description
Technical field
The utility model relates to a kind of spindle motor, the rear-mounted grinding wheel spindle motor of particularly a kind of surface grinding machine.
Background technology
The traditional type of drive of surface grinding machine grinding wheel spindle has two kinds, and the one, motor output shaft drives the rotation of belt drives grinding machine spindle by belt pulley, and this system architecture complexity is unfavorable for the bistrique gyration of grinding machine, the loss in efficiency that belt transmission is also certain.Another is that rearmounted asynchronous motor directly drives, and asynchronous motor exists volume big, the defective that power density is little.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of surface grinding machine rear-mounted grinding wheel spindle motor.The utility model can enlarge the bistrique angle range, promotes the application surface of surface grinding machine, and has strengthened the security of using.
For achieving the above object, the technical solution adopted in the utility model is: the rear-mounted grinding wheel spindle motor of a kind of surface grinding machine, it is characterized in that: comprise shell, main shaft, the p-m rotor assembly, stator module, encoder, drive end bearing bracket and rear end cap, described main shaft is arranged on enclosure by bearing one and bearing two, described stator module is arranged on enclosure and is positioned at the rear end of described shell, described p-m rotor assembly is installed on the main shaft, described drive end bearing bracket is installed in the front end of shell, described rear end cap is installed in the rear end of shell, rear end and described encoder that described encoder is installed in main shaft are connected with external driver, described main shaft stretches out from drive end bearing bracket, and the part that described main shaft stretches out from drive end bearing bracket is a taper surface, and the taper surface of main shaft is provided with the emery wheel bistrique.
The rear-mounted grinding wheel spindle motor of above-mentioned a kind of surface grinding machine, described emery wheel bistrique is installed on the main shaft by nut.
The rear-mounted grinding wheel spindle motor of above-mentioned a kind of surface grinding machine is provided with pad between described emery wheel bistrique and the nut.
The utility model compared with prior art has the following advantages: the utility model can enlarge the bistrique angle range, promotes the application surface of surface grinding machine.Described stator module is arranged on enclosure and is positioned at the rear end of described shell, makes overall system structure compactness of the present utility model, simple.And this spindle motor power density is much larger than asynchronous motor, and the grinding machine head stock support body is long-pending obviously to be reduced.Described main shaft is connected by taper surface with the emery wheel bistrique, has strengthened the steadiness that the emery wheel bistrique is installed, and the phenomenon that the emery wheel bistrique comes off in the course of the work can not take place, and has strengthened the security of producing.Be provided with pad between described emery wheel bistrique and the nut, further strengthened the steadiness that the emery wheel bistrique is installed, the security when further having strengthened the running of emery wheel bistrique.Of the present utility model simple in structure, easy to use, very big dissemination arranged.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
