Abstract
The utility model relates to a motor which in specific is a motor of vertical mounting type. The utility model resolves the problems of inconvenience for vertical mounting for current motor and alternative-current excavator. The motor of vertical type mounting comprises a front end cap, a back end cap and a revolution axis between the front and back end caps whose two ends are supported by bearings. One end of the front end cap of the revolution axis is supported by the combination of a ball bearing and a cylindrical roller bearing, while the back end cap is supported by the cylindrical roller bearing. The motor of vertical type mounting employs three-bearing support structure and is designed with a reasonable bearing lubricating structure bringing convenience for vertical mounting and more reliable mechanical properties. The motor of vertical type mounting is in particular applicable to alternative-current rotary drive motor in ten cubic meters.
Description
Technical field
The utility model relates to motor, is specially a kind of vertical installation motor.
Background technology
10 cubic metres of excavators that exchange transmission belong to the domestic great equipment of developing first, before this, this type of equips long-term dependence on import China, the domestic processing of having only minority enterprise can finish the part mechanical part, complete machine all is to be finished by overseas enterprise, the moving part of core technology fax becomes the restraining factors that restriction China develops this type of equipment by external directly control.The asynchronous motor that is used to turn round driving in the excavator is the important composition of the moving part of its fax.Turning motor vertical installation on the excavator of 10 cubic metres of interchange transmissions, frequent starting and stopping of power shovel motor in operation and rotating often are in overload, and bearing is caused very big impact.The bearing and the lubrication system of existing motor can't satisfy the power shovel working condition requirement, to guarantee the motor reliability of operation.
Summary of the invention
The utility model solves existing motor (horizontal installation motor) and is not suitable for vertical installation, particularly is not suitable for exchanging the problem of the excavator operating mode of transmission, provides a kind of suitable carrying to impact big, the complicated vertical installation motor of load.
The utility model is to adopt following technical scheme to realize: vertical installation motor, comprise front end housing, rear end cap and two ends by the rotating shaft of bearings between forward and backward end cap, front end housing one end of rotating shaft adopts the combined support of ball bearing and cylinder roller bearing, and rear end cap one end of rotating shaft adopts cylinder roller bearing to support.This vertical installation motor adopts three bearing support structures, can bear the impact that Fraquent start and rotating cause bearing in the machine operation.
The bearing support structure of vertical installation motor described in the utility model has adopted three bearing support structures, and has designed rational bearing lubrication structure, makes this motor be fit to vertical installation and makes its mechanical performance more reliable.This vertical installation motor is particularly useful for 10 cubic metres of revolution drive motors that exchange the excavator of transmission.
