Description

Levigator

The present invention relates to a kind of levigator that is used for terrazzo floor and hard stone material such as granite, marble, dolomite etc. are carried out grinding, on its mill abrading block is housed, walking mechanism and operating mechanism are housed on body, electric controller is housed on operating mechanism, the main shaft of power motor vertically is bearing on the metal (upper, and its lower end directly connects by the rigid connection mode mutually with the endoporus of the afterbody of a direct connection bulb.

At present, the motor power of commercially available levigator is many passes to mill by belt drive unit or gear drive; Adopt of water system carried out centralized water supply by water hole, mill center more; Walking mechanism adopts common non-eccentricity bearing structure to be contained on the body.The applicant is utility model " elasticity associated mode the levigator " (application number: disclosed a kind of improved structure 90211772.6) to Patent Office of the People's Republic of China's application January 23 nineteen ninety, electric machine main shaft vertically is bearing on the bearing, the direct endoporus with a direct connection bulb afterbody in its lower end connects, in the pit on the head insertion mill of direct connection bulb, moment of torsion is passed to mill by moment connection dishes such as flexibilities, carries out grinding thereby drive abrading block.But these levigators all have the some shortcomings part, and perhaps structure is complicated, heavy, manufacturing cost is higher, perhaps uses very flexible, and energy consumption is higher, and production efficiency is low, and perhaps poor reliability needs often to change other parts.

Purpose of the present invention just is: motivation transfer motion part, water system, walking mechanism to existing levigator are improved, and provide a kind of simple in structure, low cost of manufacture, the levigator that use is flexible, reliable, energy consumption is lower, efficient is higher.

The present invention realizes its purpose like this: this levigator design has a rigid connection dish, on the connection dish mill is housed, and abrading block is housed on the mill; Walking mechanism and operating mechanism are housed on body, electric controller is housed on operating mechanism; The main shaft of power motor vertically is bearing on the upper and lower bearing, and its lower end connects by the rigid connection mode mutually with the endoporus of the afterbody of a direct connection bulb, and the head of direct connection bulb inserts in the pit of rigid connection dish, and like this, electric machine main shaft is the main shaft of mill just; Direct connection bulb head is equipped with following of the bulb and the bulb seat of honour outward, and the bulb end cap is equipped with in the bulb seat of honour and rigid connection dish top; The oriented combination arm that stretches out all around on the direct connection bulb, design has flexible nominal torque transmission mechanism and rigidity excess load torque-transmitting mechanisms between this combination arm and rigid connection dish, during operate as normal, transmit the moment of torsion that motor produces by flexible nominal torque transmission mechanism, when excess load, transmit Motor torque by rigidity excess load torque-transmitting mechanisms; Design has straight-through endoporus on the axis direction of electric machine main shaft and direct connection bulb, vertically leads to the water hole, center on the rigid connection dish, and the straight-through endoporus upper end of electric machine main shaft connects mutually with flow pipe, constitutes the axial-flow type water system together; Walking mechanism is contained on the body with eccentric semiaxis structure.When levigator is worked, Motor torque is directly passed to the direct connection bulb through electric machine main shaft, its nominal torque is passed to the rigid connection dish by flexible nominal torque transmission mechanism, pass to the mill that is contained on the rigid connection dish again, be set in a rotary motion, thereby drive the abrading block rotation, grinding is carried out on ground or stone material; When traffic overload, just transmit moment of torsion by rigidity excess load torque-transmitting mechanisms.Simultaneously, motor is directly passed to the direct connection bulb by electric machine main shaft from reconstituting normal pressure, passes to rigid connection dish and mill again, thereby obtains the normal pressure of grinding.

The present invention can also realize its purpose like this: flexible nominal torque transmission mechanism is made of the elastic tyre that is contained between direct connection bulb combination arm and the rigid connection dish, the upper end of elastic tyre by pressing plate and screw in compression on combination arm, the lower end of elastic tyre by bulb end cap and screw in compression on the rigid connection dish.

Rigidity excess load torque-transmitting mechanisms of the present invention is made of end face pawl on the direct connection bulb combination arm of working in coordination and the end face pawl on the bulb end cap.

The bearing of supporting motor main shaft of the present invention all adopts radial thrust bearing, and shim is equipped with in its upper bearing (metal) top, and its below design has oil-sealing arrangement.

Because power drive system of the present invention has adopted the associated mode structure of vertical installation, power transmission shaft and electric machine main shaft are combined into one, the mode that the moment of torsion transfer mode has adopted flexible nominal torque transmission mechanism and rigidity excess load torque-transmitting mechanisms to combine, the moment of torsion transmission is reliable: water system has adopted and has designed in electric machine main shaft and the axial-flow type way of supplying water of the straight-through endoporus in the direct connection bulb, can play cooling effect to motor simultaneously; Walking mechanism has adopted eccentric semiaxis structure to be contained on the body, can adjust the height of walking rubber tire by its rotation easily; The direct connection bulb has universal property etc.Therefore, the present invention compares with other similar products, reduce surplus other parts 50, the very simple exquisiteness of structure, though 20 kilograms of complete machine weight savings, and normal pressure has increased the 20-30 kilogram on the contrary, thus the complete machine low cost of manufacture and easy to use flexibly, reliability is high, energy consumption is low (on average grind one square metre of ground and stone material can economize on electricity 0.21 degree), grinding efficiency improves greatly.

Further specified below in conjunction with drawings and Examples, described but the present invention is not limited in the concrete structure of present embodiment.
