用无级调速电机用蜗轮蜗杆控制内齿轮(1)或(2)的目的,使内齿轮的转数由低到高或由高到低无级的变化,输出轴(20)得到无级的转数输出,如果输入轴(16)装接普通交流电机也能获得无级调速装置,而且是调速范围很宽,扭矩范围很宽。 A variable speed motor for the purpose of internal control worm gear (1) or (2), so that the number of revolutions of the internal gear is obtained from low to high or high to low level no change, the output shaft (20) stepless the number of revolutions of the output, if the input shaft (16) attached to a general AC variable speed devices can be obtained, and a wide speed range, a wide range of torque.

蜗轮(7C)安装在输出轴(20)上,蜗杆(8C)安装在外壳(23)上,也可以安装电磁离合器,其目的是控制输出轴(20)继续转动,或迅速同步停止转动,下边有详细论述。 Worm wheel (7C) mounted on the output shaft (20), a worm (8C) mounted on the housing (23), can also be installed an electromagnetic clutch, which is designed to control an output shaft (20) continues to rotate, or to synchronize stopped, lower there are discussed in detail.

2、详细描述之二:不用电磁离合器,单纯用蜗轮蜗杆控制的实现,“A”、“B”、“C”、“D”无级调速装置,请见结构总成001;002;003;003A(第20页图)004;004A;006;007;008也代表着用齿轮做调速机构控制的示意图,这是一种结构简单制造安装容易的无级调速装置,在接在输入轴(16)上的电机是主电机(30)用一般的交直流电机都可以,但是装在蜗杆上的电机必须采用无级调速电机才能实现无级调速装置,因为:蜗杆在无级调速电机驱动下,蜗轮(7)内齿轮(1)或外齿轮(2)也随着无级的转动,所以输出轴(20)是无级的转动输出,这样就实现了无级调速装置。 2, a detailed description of the two: no electromagnetic clutch, to achieve with simple control of the worm, "A", "B", "C", "D" variable speed device, see structural assembly 001; 002; 003 ; 003A (of FIG. 20) 004; 004A; 006; 007; 008 also represents a schematic view of the control mechanism do speed gear, which is a simple structure and easy manufacture and installation of the variable speed means, connected to the input shaft the motor (16) is a main motor (30) using a general AC and DC motor can be, but the motor must be mounted on the worm using variable speed variable speed motor means in order to achieve because: the worm stepless lower speed motor drive, the worm wheel (7) of the gear (1) or the outer gear (2) along with stepless rotation of the output shaft (20) is stepless output rotation, thus achieving a variable speed device .

当输入轴(16)高速旋转时,内齿轮(1)固定不动,输出轴(20),只有单一的低速输出,成为改进前的减速器。 When (16) high-speed rotation of the input shaft, the internal gear (1) is stationary, the output shaft (20), only a single low-speed output, before the speed reducer becomes improved. 当内齿轮(1)做成活动的可转动的安装蜗轮(7)用花键螺母锁紧固牢,蜗杆(8)两端安装止推轴承,装入外壳(9)内,蜗杆一端安装无级调速电机实现无级调速。 When the inner gear (1) is made active rotatably mounted worm wheel (7) secured spline nut, the worm (8) is mounted at both ends of the thrust bearing, into the housing (9), mounted at one end of the worm None stepless speed governing motor.

当蜗轮的转数由低到高,由高到低无级变化时,内齿轮(1)也如此变化,当内齿轮(1)的转向与输出轴(20)同向时则输出轴(2)转数等于两个转数相加,方向相反时则输出轴(20)转数等于两个转数相减,而扭矩也是相加和相减的变化。 When the number of revolutions of the worm gear from low to high, from high to low when the infinitely variable, the internal gear (1) is also such a change, when (20) with the internal gear (1) with a steering output shaft, the output shaft (2 ) the number of revolutions equal to the number of revolutions adding two, opposite the direction of the output shaft (20) the number of revolutions equal to the number of revolutions of two subtraction, and addition and subtraction is the torque change.

这种无级调速装置的性能是,设改进前减速器的输出轴(20)的转数为20转/分,改进后用蜗轮蜗杆控制内齿轮的转数,由低到高变化,假设变化到最高1000转时分,转向相同时,则输出轴(20)的转数为20+1000=1020转/分,转向相反时,则20+(-1000)=-980转/分如果反向转数为-20,输出轴(20)的转数为20+(-20)=0转/分,这时转数范围为零/分,最高输入转数/分。 This means that the performance of variable speed, number of revolutions of the front output shaft gear disposed improvement (20) is 20 rev / min, with the improved control of the number of revolutions worm gear change from low to high, assuming is changed to the maximum 1000 rpm division, steering the same, the number of revolutions of the output shaft (20) is 20 + 1000 = 1020 r / min, turn in the opposite, then 20 + (- 1000) = --980 rev / min if the reverse -20 number of revolutions of the number of revolutions of the output shaft (20) is 20 + (- 20) = 0 r / min, then zero speed range / min, the maximum number of input revolutions / min. 它的三种转数为0转/分,-980转/分,+1020转/分。 It three rotation number 0 r / min, -980 rpm / min, + 1020 r / min.

3、详细描述之三:实现微米级(μ)进给传动的方法。 3, a detailed description of three: achieve micron ([mu]) to a feed drive method.

将输入轴(16)接交流变频无级调速电机,转数范围为45-4500转/分,速比1∶100(请见青海第一机床厂的×H754卧式加工中心主传动)“A”、“B”、“C”、“D”这四种调速装置,均可以串联,并联,混联使用,串联时输出轴(2)可以当输入轴(16)那样使用,可以安装各种离合器和调速机构,使其自由变速。 The input shaft (16) connected with AC frequency variable speed motor, speed range of 45-4500 rpm / min, ratio 1:100 (see Machine Tool Plant Qinghai × H754 horizontal machining center main drive) " A "," B "," C "," D "four speed control apparatus can be connected in series, parallel, hybrid use, in series output shaft (2) when the input shaft (16), as used, can be installed various clutches and governor mechanism, its free shifting.

现在用少齿差变速装置描述:第一级少齿差变速装置的速比为i=100第二级少齿差变速装置速比为i=100简单计算述比范围:采用双级串联i=1/100×1/100×=1/10000速比范围:最高转数为4500转/分,最低转数为45×1/100×1/100=0.0045转/分,所以速比范围为:0.0045-4500转/分,如果将0.0045转/分用于滚珠丝杠进给,螺距为12MM,则理论进给量为0.0045转/分,0.0045×1200μ=5.4μ/分如果每分钟按45转进给,每转进给量为5.4÷45=0.122μ/转,这样高精度进给量只有采用调速电机才能实现微米(μ)级进给;电气控制也比普通交流电机复杂成本很高,对我国普通机床技术改造很难实现,有的厂家虽然设计制造了经济型数控机床,由于精度低,成本高,很难大面积推广。 Now with small tooth number difference transmission is described: a first stage small tooth number difference of the transmission speed ratio i = 100 small tooth number difference of the second stage of the transmission ratio i = ratio of said simple calculation range 100: two-stage series i = 1/100 × 1/100 × = 1/10000 speed ratio range: maximum number of revolutions 4500 rev / min, the minimum number of revolutions of 45 × 1/100 × 1/100 = 0.0045 r / min, the ratio range: 0.0045-4500 rev / min, if 0.0045 rev / min for the feed screw pitch of 12MM, the theoretical feed amount of 0.0045 rev / min, 0.0045 × 1200μ = 5.4μ / min at 45 revolutions per minute if feed, feed per revolution an amount of 5.4 ÷ 45 = 0.122μ / revolution, so that high-precision feed speed motor can be achieved only microns ([mu]) feed stage; electrical control costly than the complex AC motor of general machine tools technological transformation of our country is difficult to achieve, although some manufacturers design and manufacture of economical CNC, due to low precision, high cost, large area is difficult.

4、详细描述之四:主电机采用交流电机,调速装置采用无级串联实现μ级进给。 4, detailed description of the four: the main motor AC motor, stepless speed control means connected in series to achieve progressive μ.

采用普通交流电机实现高精度微米μ级进给,增加一级调速装置就可以了,成本增加几千元,就能实现μ级进给,简单计算是设主电机转数1500RPM,减速器三级串联,速比为1/100×1/100×1/100=1/1000000,计算1500×1/1000000=0.15转/分,设进给丝杠螺距为12MM=1200μ。 AC motor is used to achieve high-precision feeding stage μ m, a speed increasing device can be, costs a few thousand dollars, can achieve feed μ stage, simple calculation is provided 1500RPM number of revolutions of the main motor, reducer three tandem, ratio of 1/100 × 1/100 × 1/100 = 1/1000000, calculated 1500 × 1/1000000 = 0.15 r / min, the feed screw pitch is disposed 12MM = 1200μ.

则0.151200=1.8μ/转,如果速比再大些,螺距再小些,工人在操作电机按扭启动时采用点动法进给,就可以实现μ级进给。 Is 0.151200 = 1.8μ / revolution, then the speed ratio if larger, then smaller pitch, a worker uses jog feeding method can be realized μ level feed operation of the motor when start button. 也就是每转1μ进给。 That is 1μ feed per revolution.

本发明设计并非如此简单的就能实现μ级进级,因为行星少齿,差被动轮继续转动靠各环节的摩阻力,使输出轴(20)慢慢停止下来,这是这四种调速装置,不能广泛应用于机床,不能应用于精定位的主要原因。 The present invention is not so simple design can be realized μ level of upgrade, less because the planetary gear, the difference between the driven wheel continues to rotate against the friction resistance of each link, the output shaft (20) gradually stopped, which is four speed means not widely used in machine tools, it can not be applied to fine positioning of the main reasons. 本发明解决了这个难题,解决了办法是这样的:在输出轴(20)上安装,各种离合器调速机构当两个调速装置串联使用时,则输出轴(20)与当做输入轴(16)那样使用,本例题采用了电磁离合器,蜗轮蜗杆做调速机构做阻尼机构,使输出轴(20)与输入轴(16)同步转动同步停止,当输入轴(16)停止转动时,输出轴(20)上的电磁离合器提前几秒钟,通电使么操片吸合产生了强大的阻力,使输出轴(20)转动,当输入轴(16)启动时,输出轴上的电磁离合器,超前断电,能准确同步启动,如果采用双蜗杆控制蜗轮,因为蜗杆(8C)安装在外壳(33)上产生反作用力抵消蜗杆的轴向力,抵消惯性力,用消除间隙的双蜗杆控制蜗轮(7C),因为蜗轮(7C)用键牢牢安装在输出轴(20)上同步转动,同步停止,始终抵消被拖动物体产生的惯性力,防止爬行,这就要求双蜗杆(8C)上的电机与输入轴(16)上的 The present invention solves this problem, this approach is resolved: mounted on the output shaft (20), various speed clutch mechanism when the two control devices are used in series, the output shaft (20) and used as the input shaft ( 16) as used, the present example uses the electromagnetic clutch, the worm do governor mechanism damping mechanism to make the output shaft (20) and the input shaft (16) simultaneous rotation synchronization stopped, when the input shaft (16) stops rotating, the output the electromagnetic clutch (20) for a few seconds ahead of the axis, so that it is energized pull operation plate had a strong resistance to the output shaft (20) rotates when the input shaft (16) starts, the output shaft of an electromagnetic clutch, lead off, accurate synchronous start, if a twin-screw worm control, since the worm (8C) mounted on the housing (33) generate an axial reaction force is canceled worm, canceling an inertial force, a twin-screw worm to eliminate the gap control (7C), because the worm gear (7C) keyed firmly mounted on the output shaft (20) rotate in synchronization, the synchronization is stopped, always cancel the inertial force generated from the object being dragged, to prevent creep, which requires twin-screw (8C) on the motor and the input shaft (16) 电机用PC电器或数控控制实现自动化,双蜗杆(8C)采用不自销的三线或四线蜗杆与电机联结端采用钢球保险结合子,防止与输入轴(16)系统间的干涉,破坏零件,双蜗杆(8C)控制系统主要用于大负荷转动件,实现(μ)级进给。 Motor implemented by PC appliances or CNC control automation, twin-screw (8C) employed is not self-pin three-wire or four-wire worm and the motor coupled to the end use of the ball safety binder, (16) the interference between the systems to prevent the input shaft, destroy the parts , twin-screw (8C) load control system is mainly used for large rotor, to achieve ([mu]) stage feed. 这是一种用两台调速电机,一个驱动输入轴(16),一个驱动输出轴(2)的电机,两个电机合力驱动输出轴(20),可增大输出扭矩。 This is a two speed motor with a drive input shaft (16), a motor output shaft (2) driving the two motors driving force output shaft (20), the output torque can be increased.

四、用两轴线相交、平行齿轮、各种带、链条等例子实现本发明。 Fourth, the two intersecting axes, parallel gear examples, various belts, chains or the like to achieve the present invention. 以上说明的是用蜗杆、蜗轮电磁离合器作调速机构也可用球面蜗杆调速,螺旋齿轮传动和电磁离合器混着使用作调速机构因为他们都是两轴线交错的齿轮啮合。 Described above is a worm, the worm wheel electromagnetic clutch mechanism may also be used as a speed governor worm spherical, helical gear and an electromagnetic clutch used as mixed with the governor mechanism because they are two of skew gear engagement. 都能用于以上四种传动装置。 The above four can be used for transmission. 其方法与上述例题相同。 The method which is the same as the above examples.
