The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The present embodiment provides a torque output device.
In one embodiment, as shown in fig. 1 and 2, it includes a main motor 1, a flywheel 18, and a flywheel motor 3 that drives the flywheel 18 to rotate. The main motor 1 has a main motor shaft 15 and a main motor housing 16 as in a general rotary motor; wherein the main motor housing 16 is connected to an external device requiring rotational torque via a main motor housing flange 17. The flywheel 18 is rotatably connected to the main motor shaft 15, and the rotational axis of the flywheel 18 is not parallel to and collinear with the axis of the main motor shaft 15. The flywheel motor 3 is connected with the main motor rotating shaft 15 and is connected with the flywheel 18 in a power transmission manner.
The flywheel 18 of the device is driven to rotate by the flywheel motor 3 to become a gyroscope body, so that the device has the corresponding characteristics of a gyros. The rotation axis including the gyroscope body has the characteristic of fixing the axis in space, namely, the rotation axis is kept unchanged, in other words, the gyroscope body has resistance to axial change under the action of external force. If the gyro body is forced to change the direction of the rotating shaft by external torque, the gyro body can apply a corresponding reverse moment to the external force application object, and the moment is called gyro moment. The moment of the gyroscope is interpreted as the main moment of the God's inertia force of each constituent particle of the rigid body, the moment is positively related to the rotational inertia of the gyroscope body, the rotating speed of the gyroscope body and the swinging angular speed of the gyroscope rotating shaft, and for the device, the rotating speed of the gyroscope body is directly controlled by the flywheel motor 3, and the swinging angular speed of the gyroscope rotating shaft is influenced by the rotating speed of the main motor 1. Therefore, when the rotation axis of the flywheel 18 is not parallel and collinear with the axis of the main motor shaft 15, the main motor 1 drives the external rotating member and the rotating flywheel 18 simultaneously, and the flywheel 18 presents resistive gyroscopic moment, so the torque output device can effectively output torque to the outside without the need of firm connection of external objects. For example, when the device is applied to a floating drilling platform, the main motor housing 16 is fixedly connected with the drill rod and is in rotary connection with the drilling machine bracket, and the housing is not required to be fixedly connected like other power devices. Thus, even if the drill rod generates reverse torque in drilling operation, the drill rod does not act on the floating platform, so that the floating platform keeps stable.
It should be noted that, in order to control the rotation speed and start/stop of the main motor 1 and the flywheel motor 3, the device may be provided with a controller 4, and some rotating parts of the device may be connected with external cables through conductive slip rings and other existing technologies.
Based on the above embodiment, in a preferred embodiment, the rotational axis of the flywheel 18 intersects and is perpendicular to the axis of the main motor shaft 15. The flywheel 18 and the main motor shaft 15 in this positional relationship can obtain gyro moment as large as possible under otherwise identical conditions.
Based on the above embodiment, in a preferred embodiment, the number of flywheels 18 is two or more, and is circumferentially distributed around the axis of the main motor shaft 15. More than two flywheels 18 can provide more powerful gyroscopic torque, enhancing the torque output capability of the device. In addition, the plurality of flywheels 18, which are distributed circumferentially around the axis of the main motor shaft 15, form a gyro body as a whole, and the shaft of the connected external rotating object can be kept stable by utilizing the dead axle of the gyro body. Still take small-size floating drilling platform as an example, set up the back like this, the drilling rod just has the dead axle nature, and even small-size floating platform produces some unstability trends because of wave or strong wind etc. can also carry out impedance by a wide margin under the dead axle nature effect of this device for drilling operation can be smooth high-efficient completion.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 3, it further includes: the flywheel transmission assembly 5 is arranged between the flywheel 18 and the flywheel motor 3, and more than two flywheels 18 are driven by the same flywheel motor 3 through the flywheel transmission assembly 5. The same flywheel motor 3 drives a plurality of flywheels 18, so that the whole structure of the device is compact, and the manufacturing cost is reduced.
Based on the above embodiments, in a preferred embodiment, as shown in fig. 3 and 4, it further comprises: a transmission case 7 arranged between the flywheel 18 and the main motor shaft 15. The main motor rotating shaft 15 and the flywheel motor 3 are fixedly connected with the transmission case 7. And flywheel drive assembly 5 comprises: a main flywheel gear 8 arranged on the output shaft of the flywheel motor 3, a secondary flywheel gear 28 meshed with the main flywheel gear 8, and a flywheel rotating shaft 44 rotationally connected with the side wall of the transmission case 7. One end of the flywheel rotating shaft 44 extends into the transmission case 7 and is fixedly connected with the slave flywheel gear 28, and the other end of the flywheel rotating shaft 44 extends out of the transmission case 7 and is fixedly connected with the flywheel 18. Through the gear transmission mode, synchronous rotation of each flywheel 18 is realized, so that the gyro moment of each flywheel 18 is balanced and unified and symmetrically acts on the main motor rotating shaft 15, the shaft body and related bearing parts are prevented from being stressed unevenly, and the service life of the flywheel is prolonged.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 4, the flywheel rotation shaft 44 includes the sliding shaft 20 and the transmission shaft 22 slidably fitted over the outside of the sliding shaft 20. The sliding mating surfaces of the sliding shaft 20 and the transmission shaft 22 are non-circular in cross section (in particular, regular hexagonal in this embodiment) so as to transmit the rotational torque of the flywheel 18. The sliding shaft 20 passes through the flywheel through hole 19 and is fixedly connected with the flywheel 18 through the sliding shaft flange 21, the transmission shaft 22 is rotationally connected with the side wall of the transmission box 7, one end of the sliding shaft is connected with the slave flywheel gear 28 through the gear seat 26, and the relative position of the sliding shaft 20 on the transmission shaft 22 is adjusted through the flywheel adjusting part 6. The structure realizes the adjustable distance of the flywheel 18 relative to the axis of the main motor rotating shaft 15, so that the rotational inertia of the integral gyroscope formed by a plurality of circumferentially uniformly distributed flywheels 18 is adjustable, and the further the flywheel 18 is away from the axis of the main motor rotating shaft 15, the larger the rotational inertia of the integral gyroscope is. Because the rotation speed of the integral gyroscope can be limited by a plurality of factors, such as torque and rotation speed output by the device, the rotation speed of the integral gyroscope can not be too high, so that the related characteristics of the gyroscope are weakened, and the rotation inertia of the integral gyroscope is increased to realize stronger shaftly with lower rotation speed, so that the rotating shaft of the device can keep enough self-stability. The flywheel 18 can be contracted again under the condition of high rotation speed and strong self-stability so as to reduce the operation space occupied by the equipment. In addition, the number of the flywheels on each flywheel rotating shaft and the flywheel mass can be installed, replaced and adjusted according to the conditions, and the rotational inertia adjustment of the integral gyroscope can be further realized.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 4 and 5, the sliding shaft 20 and the transmission shaft 22 are hollow, specifically, the sliding shaft 20 is provided with a sliding shaft through hole 25, and the transmission shaft 22 is provided with a transmission shaft through hole 27. The slave flywheel gear 28 is further provided with a slave flywheel gear through hole 29, so that the whole flywheel transmission assembly 5 is of a hollow structure. The flywheel adjusting part 6 includes: an adjusting motor 45, a main adjusting gear 42, a secondary adjusting gear 35, a vertical bracket 36, a screw 34, a slide bar 30 and a slide block 31. Wherein the adjusting motor 45 is fixedly connected with the transmission case 7. The main adjusting gear 42 is provided on the output shaft of the adjusting motor 45. The slave adjusting gear 35 is engaged with the master adjusting gear 42 and is mounted on the stand 36 for rotation within the slave adjusting gear mounting hole 37. The stand 36 is fixedly connected to the gear box 7 by a gear box base 43 and is located further inside the gear box 7 (i.e. closer to the center of the gear box 7) with respect to the slave flywheel gear 28. The screw 34 is fixedly connected with the slave adjusting gear 35 through the bracket through hole 39. The slide bar 30 is inserted into the slide bar fixing hole 38 to be firmly coupled with the vertical bracket 36 and parallel to the axis of the screw 34. The slide rod 30 and the lead screw 34 are inserted into the hollow structure of the slide shaft 20 and the transmission shaft 22 through the flywheel gear through hole 29. The slider 31 is slidably connected to the slide rod 30 through a slider through hole 33, and is screwed to the screw 34 through a slider screw hole 32. The sliding block 31 is rotatably connected with the sliding shaft 20, and the sliding block 31 is limited in the axial direction of the sliding shaft 20, specifically, in this embodiment, a sliding block limiting hole 23 is formed in the side wall of the sliding shaft 20, the sliding block limiting hole 23 is in a groove shape, the groove width is larger than the diameter of the sliding shaft through hole 25, and when the sliding block 31 is inserted into the groove, the sliding block 31 can not only rotate, but also be limited in the axial direction.
The flywheel adjusting part 6 with the structure can lead each flywheel 18 to obtain synchronous axial positioning adjustment, ensure the symmetry among the parts in the adjustment process, namely ensure the quality balance, and not affect the mechanical property of the whole device. In addition, the structure is very compact, the middle space formed by meshing the main flywheel gear 8 and the auxiliary flywheel gear 28 is skillfully utilized, and the hollow flywheel transmission assembly 5 is utilized to complete the arrangement of the adjusting assembly, so that the whole volume of the device is not excessively increased.
In a preferred embodiment, as shown in fig. 3 and 4, in order to fix the transmission shaft 22 in the axial direction, the transmission shaft 7 may be provided with a transmission shaft step 24 with a larger diameter, so that the transmission shaft step 24 rotates in the transmission shaft 13, and the shaft body of the thinner transmission shaft 22 is provided with the transmission cover 9 with the transmission cover through hole 14 in a penetrating manner, and the transmission cover 9 is fixed on the transmission case 7.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 5, the sliding rod 30 has a U shape, the U-shaped head (i.e., one end of the opening) of the sliding rod 30 is fixedly connected to the vertical bracket 36, and both sides of the U shape of the sliding rod 30 are slidably connected to the sliding block 31. Because the slide bar 30 is a cantilever support structure. In the use state, the sliding rod 30 is subjected to corresponding torque due to the friction force of the rotating sliding shaft 20 on the sliding block 31, and is easy to deflect, so that the sliding rod is not parallel to the screw rod 34 any more, and further the sliding block 31 is blocked. The U-shaped slide bar 30 not only simply increases the matched rod piece on the other side to enable the double bars to bear force, but also enables the two bars to be integrated because of the connection of the tail ends (the closed end of the U-shaped), has higher structural strength, prevents torsional pendulum deflection in a cantilever structure and ensures the normal operation of equipment.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 2 and 3, the main motor shaft 15 is provided with corresponding flanges, the transmission case base 43 is provided with a transmission case base flange 41, and the transmission case bottom surface is provided with a transmission case bottom flange 12, and the three flanges are stacked and fixedly connected to each other. And a transmission case top flange 10 is arranged at the top end of the transmission case 7 and used for connecting the flywheel motor 3, and the output shaft of the flywheel motor 3 extends into the transmission case 7 from a main flywheel gear mounting hole 11. The adjusting motor 45 is installed in the inner cavity of the transmission case base 43, and the output shaft thereof passes through the main adjusting gear installation hole 40 to be connected with the main adjusting gear 42, and the transmission case base 43 is integrally and fixedly connected in the transmission case 7. The main motor 1 and the flywheel motor 3 are respectively positioned at two ends of the transmission case 7, and the adjusting motor 45 is arranged in the transmission case 7, because the main motor 1 is a power output main part, and the volume ratio is larger; the flywheel motor 3 is relatively small in power and large in external dimension because of the need of providing high angular momentum for a plurality of flywheels 18; while the adjustment motor 45 only powers the adjustment of the flywheel 18 position, so that the power is smaller and the size smaller. Therefore, the overall structure of the motor position placement layout device is very compact, compared with other layout schemes, the structure size of the transmission case 7 can be reduced, and the total weight and the material consumption are reduced.
Based on the above embodiment, in a preferred embodiment, as shown in fig. 2 and 3, the transmission case 7, the flywheel motor 3 and the adjustment motor 45 are all symmetrical, and the symmetry axis of the transmission case 7, the symmetry axis of the flywheel motor 3, the symmetry axis of the adjustment motor 45 and the axis of the main motor shaft 15 are on the same straight line. Since the motor and the gear box 7 are components having relatively high mass except the flywheel 18 in the present device, in the above layout, the flywheel motor 3, the adjustment motor 45 and the gear box 7 are all symmetrical in structure and the centers thereof are all overlapped, so that the gyro mass distribution constituted by a plurality of flywheels 18 can be balanced, and a better dead axle can be obtained.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present invention.
