Abstract
The utility model relates to a motor of a screw press, and concretely relates to a special motor-driven structure used for an electric screw press, the special motor-driven structure used for electric screw press comprises a motor body and a driving shaft, a belt pulley is arranged on the driving shaft, a bearing is arranged in a center installing hole of the belt pulley, a support shaft is arranged in the bearing, and the support shaft is connected to a motor-driven body through a support. According to the utility model, the support shaft is arranged in the bearing, the support mechanisms are provided at two sides of the belt pulley, a cantilever beam type structure with single point support in the prior art can be changed, the driving shaft smooth operation can be guaranteed, the transmission precision of the driving shaft is increased, and the phenomena of bending or fracture of the driving shaft can not be generated even bears heavy duty or variable load.
Description
Technical field
The utility model relates to the motor of fly press, is a kind of motor special Drive Structure for electric screw press specifically.
Background technology
The driving shaft of the motor special of existing electric screw press is the beam type structure after belt pulley generally is installed, this structure is when bearing heavy duty, variable load, motor driving shaft is except being subjected to outside alternately moment of torsion acts on, also may bear certain Moment, cause the motor driving shaft running uneven, produce abnormal vibrations, thereby cause that the phenomenons such as twist and warping fracture easily occur motor driving shaft, make the useful life of motor shorter, fail safe is relatively poor.
The utility model content
For above-mentioned technical problem, the utility model provides the motor special Drive Structure that is used for electric screw press that a kind of running is steady, fail safe is higher.
The technical scheme in the invention for solving the above technical problem is: a kind of motor special Drive Structure for electric screw press, comprise motor body and driving shaft, on this driving shaft, belt pulley is installed, be provided with a bearing in the center mounting hole of described belt pulley, one back shaft is installed in this bearing, and this back shaft is fixedly connected with body by support.
As can be known from the above technical solutions, the utility model by bearing at motor pulley upper support axle, make belt pulley both sides all have supporting mechanism, changed the structure of beam type of the single-point support of prior art, thereby guarantee the driving shaft smooth running, improve the driving shaft transmission accuracy, even bear heavy duty or variable load, bent propeller shat or the phenomenon of fracture can not occur yet.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
Motor special Drive Structure of the present utility model comprises motor body 1 and driving shaft 2, belt pulley 3 is installed on this driving shaft, belt pulley drives press motion by belt 7, be provided with a bearing 4 in the center mounting hole of described belt pulley, one back shaft 5 is installed in this bearing, this back shaft is fixedly connected with body by support 6, and described support can make supporting seat etc.When driving shaft drove the belt pulley rotation, belt pulley one side had driving shaft to support, and opposite side has back shaft to support, thereby formed two fulcrum support structures, compared with existing single-point support structure, and the output balance quality of its driving shaft is better.
Due to the two fulcrum support of the utility model employing mechanism, belt pulley and driving shaft stressed than balance, the vibration and the noise that produce in the time of can reducing running, transmission accuracy is higher, security performance is better, and physical life is longer, even bear heavy duty or variable load, bent propeller shat or the phenomenon of fracture can not occur yet, and have improved the adaptability of this motor.
Above-mentioned execution mode is only for illustration of the utility model, and be not to be to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that do not break away from the utility model spirit and scope, can also make various variations and modification, so all technical schemes that are equal to also should belong to category of the present utility model.
