Abstract
The utility model relates to a transmission mechanism of a vertical lathe main motor. The transmission mechanism comprises the motor, and the power is transmitted to a transmission shaft through a motor coupler, then is transmitted to a rigid coupler through the transmission shaft and lastly is transmitted to a gearbox through the rigid coupler. The transmission mechanism is characterized in that the motor coupler is an elastic pin coupler, and the double-key symmetrical linkage transmission method is adopted in the transmission shaft. The motor is moved rightwards to shorten the transmission shaft by one third and increase the external diameter of the transmission shaft by the range between 1mm and 5mm. The double-key linkage is adopted in the rigid coupler. The circumference surface of one end of the motor coupler is welded with a guiding sleeve. The transmission mechanism is low in cost, high in rigidity and bearing capacity, large in transmission power and accurate and stable in transmission.
Description
[technical field]
The utility model relates to machinery manufacturing technology field, relates to a kind of vertical lathe main motor transmission mechanism.
[background technology]
The vertical car of the 3.4mm queen post that many producers are often used, the motor that its main drive gear power source of C534J is 55KW, it passes to gearbox through power transmission shaft by power by shaft coupling.Its structure as shown in Figure 1, motor reel 1 is by helical spring shaft coupling 2, power is passed to the power transmission shaft 3 of fixed mounting base, and then through positive coupling 5, pass to gearbox 6, this structural requirement motor output shaft center, center, power transmission shaft fixed mounting base hole, high-speed shaft of gear box center three must be positioned on same axial line, and guaranteeing coaxially could the normal delivery torque.If the different axis of three, the rotating mechanism imbalance, due to the impact of inertia force, increase and the fluctuation of supporting force appear, damage bearing when serious, lower efficiency, produce noise, make basic vibration-generating or resonance, even make helical spring shaft coupling mating surface produce and press feedback to lose efficacy, spring is distorted, the keyway at fracture, power transmission shaft two ends rolls key and tears phenomenon, so that can't maintain the normal operation of this mechanism.
If this lathe puts into production use, year for a long time, long-term vibration can make immerge, two column generation global displacements (sink and tilt), thus cause cardan-shaft suspension Zuo Kong center to move down (because supporting base is arranged on the column side) so that produce the different axis of three.Along with the increase of this kind of duration of service, it is more and more frequent that this kind of phenomenon occurs, even cause just changing one less than two months and want power transmission shaft, less than the result of just changing a pair of shaft coupling in 1 year.And this kind of shaft coupling very difficult purchase on market, both had a strong impact on production, increased a lot of workloads to machine maintenance again.Draw mechanism and all be arranged in melt pit, keep in repair extremely inconvenient.
[summary of the invention]
Shortcoming for prior art, technical problem to be solved in the utility model, overcome exactly the deficiency of above-mentioned prior art, provide a kind of with low cost, rigidity than the vertical lathe main motor transmission mechanism high, that bearing capacity is strong, transmitted power is large and transmission is stable.
The technical solution adopted in the utility model is: a kind of vertical lathe main motor transmission mechanism, comprise motor, power is transferred to power transmission shaft, is transferred on positive coupling by power transmission shaft by motor coupling, transmit power to gearbox by positive coupling, it is characterized in that: described motor coupling is elastic dowel pin shaft coupling, and described power transmission shaft adopts the symmetrical kind of drive connected of two keys.
Further, described motor is moved to right and shortens 1/3rd of described propeller shaft length, increase its external diameter 1～5mm.
Further, described positive coupling is two key connecting.
Further, a fairlead of welding on an end periphery of described elastic dowel pin shaft coupling.
The beneficial effects of the utility model are: this vertical lathe main motor transmission mechanism is with low cost, rigidity than high, bearing capacity is strong, transmitted power is large and transmission is precise and stable.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is the structural representation of the main motor transmission mechanism of prior art vertical lathe;
Fig. 2 is structural representation of the present utility model;
In figure: 1 motor reel, 2 helical spring shaft couplings, 3 power transmission shafts, 4 movable axis supporting bases,
5 positive couplings, 6 gear-box axles, 7 columns, 8 gearboxes, 9 motor, 10 elastic dowel pin shaft couplings
[specific embodiment]
Referring to accompanying drawing 2, the utility model has adopted a kind of vertical lathe main motor transmission mechanism, comprise motor 1, power is transferred to power transmission shaft 3, is transferred on positive coupling 5 by power transmission shaft 3 by motor coupling, transmit power to gearbox 8 by positive coupling 5, it is characterized in that: described motor coupling is elastic dowel pin shaft coupling 10, and described power transmission shaft 3 adopts the symmetrical kind of drive connected of two keys.
Employing resilient key shaft coupling 10 rigidity are higher, bearing capacity is high, transmitted power is larger, adopt the symmetrical joint transmission modes of two keys, make power transmission shaft 3 bilateral symmetry transmitting torques, improve its transmission stability.
Further, described motor 1 is moved to right and shortens 1/3rd of described power transmission shaft 3 length, increase its external diameter 1～5mm.
Further, described positive coupling 5 is two key connecting.
Further, a fairlead of welding on an end periphery of described elastic dowel pin shaft coupling 10.
Contrast accompanying drawing 1, the movable axis supporting base 4 that will connect with column 7 removes, cut down the number of intermediate links, motor is moved to right, shorten propeller shaft length, increase its external diameter, can improve transmission person's rigidity, connect with gear-box axle 6 with two key positive couplings, finally a fairlead of welding on motor coupling one end periphery, two half a couplers are fixed on same axis, guarantee the two coaxial rotation.
The preferred embodiment that this utility model has been described at this, comprise that the inventor is for implementing known optimal mode of the present utility model.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.The inventor wishes the change that the those of ordinary skill rational Application is such, and the inventor thinks and clearly states different application at this and also can realize the utility model.Therefore, the utility model comprises all modifications and the equivalents of the purport of quoting in the claim of enclosing, and this allows in applicable law.In addition, any combination of all possible change of above-mentioned key element is also comprised by the utility model, unless pointed out in addition or obvious contradiction in context at this.
