High shock resistance of the ball mill gearbox

The ball mill gearbox cam has exactly one eccentric section less than the pin ring has pins. A 360° revolution of the crankshafts therefore causes the cams to rotate one pin farther, whereby practically all the gear teeth are in continuous contact with the pins. The rotating movement is then transmitted from the input shaft to the crankshafts via the spur gear stage, and these then shift the cams in the pin ring and, consequently, generate a reduced speed with high precision. This technology enables the small worm gearbox gears to absorb 5 times the rated torque in emergency-stop situations without suffering any damage. The resulting overall reduction is the same as the product of the two reduction ratios (spur gear stage and eccentric stage).

Cycloidal gear reducers a “normal class” of quality

Cycloidal gear reducers are supplied with mounting flanges must be assembled with motors whose shaft and flange tolerances correspond to a “normal class” of quality in order to avoid vibration and forcing of the input bearing. Motors supplied guarantee that this requirement is fulfilled. For ease of consultation, the correspondence of the size of the B5 and B14 motor with the sizes of the shaft and the motor connection flange are shown in the following table.

hollow shaft gearmotor, as the motor connection flanges are separate from the body it is also possible to have a shaft / flange combination that does not correspond to the table, e.g. 19/140, thereby offering adaptability for other non-unified models such as the brushless or direct current types.

cycloidal speed reducers are precision gearmotor

cycloidal speed reducers are supplied complete with synthetic oil and therefore do not require any maintenance. The size 110 and 130 gears are supplied with the quantity of mineral oil foreseen for the B3 assembly position. It is the client’s responsibility to adapt the quantity of oil to the assembly position and in addition, to substitute the filling plug, supplied closed for transport reasons, with the one equipped with a hole attached to the gear. If the breather plug is not installed it may create internal pressure with a consequent leakage of oil from the oil seals.

The speed increaser gearbox can be designed with standard

Torkdrive Cycloidal gear reducers is that the bearing and the sun gear are an unbalanced mass, and will cause some vibration. In my design, the eccentricity is minimal (around 0.13 mm), and the effect is barely perceptible; but in large-scale applications, it is sometimes necessary to use two bearings and two sun gears, 180° off-phase, to compensate for the problem.

The speed increaser gearbox can be designed with standard, involute tooth profile - but given the large meshing area, and the desire to minimize tooth height (in order to allow the gears to have almost the same diameter), I decided to use a computed circular profile, instead. Tooth height is 0.24 mm, and width is 0.43 mm, allowing the inner gear to have 80 teeth, and the outer gear to have just 81.

Torkdrive cycloidal speed reducer by the action of the eccentric cam

Torkdrive cycloidal speed reducer ,If you do the math, the transmission ratio of this mechanism is (Cring - Csun) / Csun. In other words, if Csun is 65 mm (diameter of ~20.5 mm), and Cring is 65.5 mm, the ratio is 130:1. If you used spur gears or a planetary gearbox, it would be difficult to achieve 8:1 or so in the same envelope.

speed increaser gearbox ,The problem, of course, is that if we attach the output shaft directly to the sun gear, the resulting motion will be a composite of two patterns: the slow rotation we are interested in, and the rapid wobble caused by the action of the eccentric cam. And that's where the other clever trick comes into play: create a set of oversized holes in the ring gear, and couple a centrally mounted output carriage to these holes using a set of undersized pins.

Torkdrive Cycloidal gear reducers have a rotating shaft

Torkdrive Cycloidal gear reducers have a rotating shaft of a motor (center) attached an eccentric cam (orange) that rotates feely inside a ball bearing; that bearing, in turn, is in the center of a sun gear (green) that rolls inside a fixed ring gear (blue). In the leftmost drawing, the cam is facing up, cycloidal speed reducers keeps the sun gear in contact with the top of the ring gear. As the motor shaft beg cins to rotate clockwise, the contact point follows this motion, and the sun gear rolls inside the ring. Because the circumference (C) of the rolling gear is smaller than that of the ring, any point on its surface will effectively slowly rotate counterclockwise.

Torkdrive Helical Bevel Geared Motors relative motion

Torkdrive Helical Bevel Geared Motors disk will cause vibration in the drive which will propagate through the drive/driven shafts. This will also cause increased wear on the exterior teeth of the cycloidal disk, as well as the interface with the output roller pins due to small relative motion caused by the vibrations. Helical Worm Geared Motors ,A second cycloidal disc installed a half-rotation relative to the first will balance the input shaft and reduce vibration.

high power density for Torkdrive Helical Worm Geared Motors

Torkdrive Helical Worm Geared Motors are angular geared motors where the gear unit output shaft is rotated through 90° to the motor shaft. Helical worm Gearmotor units can either have a solid or a hollow shaft. Helical bevel geared motors represent the ideal solution for drive tasks where an angular geared motor with high power density is required with continuously high output torques.

smoothly and quietly of Torkdrive cycloidal speed reducer

Torkdrive cycloidal speed reducer operate more smoothly and quietly compared to spur gears due to the way the teeth interact. The teeth on a helical gear cut at an angle to the face of the gear. When two of the teeth start to engage, the contact is gradual--starting at one end of the tooth and maintaining contact as the gear rotates into full engagement. The typical range of the helix angle is about 15 to 30 deg. The thrust load varies directly with the magnitude of tangent of helix angle. gear motors is the most commonly used gear in transmissions. They also generate large amounts of thrust and use bearings to help support the thrust load. Helical gears can be used to adjust the rotation angle by 90 deg. when mounted on perpendicular shafts. Its normal gear ratio range is 3:2 to 10:1.
