Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. For convenience of description, the rotation directions of the components rotatably mounted in the three directions X, Y, Z are defined as follows: referring to fig. 1, when viewed from the left side, the counterclockwise rotation of the rotor spindle 20 and the drive bevel gear 24 is forward rotation, and the clockwise rotation is reverse rotation; when viewed from a top view, the clockwise rotation of the forward worm gear transmission shaft 31 and the forward bevel gear 34 is forward rotation, and the clockwise rotation is reverse rotation; when viewed from the front, the forward worm wheel 35 and the reverse worm wheel 45 rotate in the counterclockwise direction as forward rotation, and rotate in the clockwise direction as reverse rotation.
Referring to fig. 1 and 2, the flexible speed-reducing motor with dual output shafts working in series according to the present invention includes a motor housing, a rotor spindle 20 installed with its axis parallel to the X-axis and rotating in the X-direction, a forward worm gear transmission shaft 31 and a reverse worm gear transmission shaft 41 installed with their axes parallel to the Y-axis and rotating in the Y-direction, and a forward output shaft 36 and a reverse output shaft 46 installed with their axes parallel to the Z-axis and rotating in the Z-direction. The rotor spindle 20, the forward worm transmission shaft 31, the reverse worm transmission shaft 41, the forward output shaft 36 and the reverse output shaft 46 can rotate around the axes thereof. Wherein the X axis, the Y axis and the Z axis form a Cartesian orthogonal coordinate system and belong to a right-handed spiral coordinate system.
The motor further comprises a rotor 21 and a stator which drive the rotor spindle 20 to rotate, a drive bevel gear 24 fixedly arranged on the rotor spindle 20, a forward bevel gear 34 arranged on the forward worm transmission shaft 31 through a one-way bearing A32 and meshed with the drive bevel gear 24, a reverse bevel gear 44 arranged on the reverse worm transmission shaft 41 through a one-way bearing B42 and meshed with the drive bevel gear 24, a forward worm wheel 35 fixedly arranged on the forward output shaft 36, a reverse worm wheel 45 fixedly arranged on the reverse output shaft 46, a metal spiral spring A37 wound on the forward worm transmission shaft 31 and flexibly meshed with the forward worm wheel 35 for transmission, and a metal spiral spring B47 wound on the reverse worm transmission shaft 41 and flexibly meshed with the reverse worm wheel 45 for transmission. In order to improve the deceleration effect and the rotational stability, the radius of the forward bevel gear 34 is equal to the radius of the reverse bevel gear 44, and both are larger than the radius of the drive bevel gear 24; the metal coil spring A37 and the metal coil spring B47 play a role of a flexible worm, and can absorb impact kinetic energy when the load of the forward output shaft 36 and the reverse output shaft 46 changes suddenly, so that the rotation stability of the forward worm wheel 35 and the reverse worm wheel 45 is improved.
When the drive bevel gear 24 rotates in the forward direction in the YZ plane, the forward bevel gear 34 drives the forward worm gear transmission shaft 31 to rotate synchronously by virtue of the attribute 'the outer ring cannot rotate reversely relative to the inner ring' of the one-way bearing a32, and then drives the forward output shaft 36 to rotate in the forward direction in the XY plane by flexibly meshing the metal spiral spring a37 with the forward worm gear 35; the reverse bevel gear 44 is idle-rotated around the reverse worm-gear transmission shaft 41, and the reverse worm-gear transmission shaft 41 is stationary, so that the reverse output shaft 46 is kept stationary. When the drive bevel gear 24 rotates reversely in the YZ plane, the forward bevel gear 34 idles around the forward worm gear transmission shaft 31, so that the forward worm gear transmission shaft 31 is stationary, thereby keeping the forward output shaft 36 stationary; meanwhile, the reverse bevel gear 44 drives the reverse worm gear transmission shaft 41 to rotate synchronously by virtue of the property that the outer ring cannot rotate reversely relative to the inner ring of the one-way bearing B42, and then drives the reverse output shaft 46 to rotate in the positive direction in the XY plane by flexibly meshing the metal coil spring B47 with the reverse worm gear 45. Both ends of the metal spiral spring B47 are fixedly arranged on the reverse worm gear transmission shaft 41, and when the impact kinetic energy is small, the metal spiral spring B47 and the reverse worm gear transmission shaft 41 keep relatively static; when the impact kinetic energy is larger, the part of the spring wire in the metal spiral spring B47, which is meshed with the reverse worm wheel transmission shaft 41, generates certain energy-absorbing deformation. The structure and operation principle of the metal coil spring a37 are the same as those of the metal coil spring B47.
Preferably, the motor housing includes a left side plate 11, a right side plate 12, an upper side plate 13, a lower side plate 14, a front side plate 15, and a rear side plate 16. The left side plate 11 and the right side plate 12 are parallel to the YZ plane, the upper side plate 13 and the lower side plate 14 are parallel to the XZ plane, and the front side plate 15 and the rear side plate 16 are parallel to the XY plane; the left side plate 11, the upper side plate 13 and the front side plate 15 are perpendicular to each other two by two. One end of the rotor spindle 20 is mounted on a left bearing seat 25 fixedly connected with the left side plate 11 by adopting a rolling bearing A26, the upper end of the forward worm gear transmission shaft 31 is rotatably mounted on the upper side plate 13, and the lower end of the reverse worm gear transmission shaft 41 is rotatably mounted on the lower side plate 14; the two ends of the positive output shaft 36 are respectively rotatably mounted on the rear side plate 16 and the front side plate 15, and the front end thereof passes through the front side plate 15 and extends to the outside of the motor housing; the reverse output shaft 46 is rotatably mounted at both ends thereof to the rear side plate 16 and the front side plate 15, respectively, and extends at its front end through the front side plate 15 to the outside of the motor casing. In specific implementation, the adjacent two sides of the upper side plate 13 and the lower side plate 14 are respectively and fixedly provided with an upper bearing seat 51 and a lower bearing seat 53, one end of the forward worm gear transmission shaft 31 is rotatably connected with the upper bearing seat 51 by adopting a rolling bearing B52, and the other end of the forward worm gear transmission shaft is rotatably connected with the lower bearing seat 53 by adopting a rolling bearing C54; a front bearing seat A61 and a front bearing seat B65 are fixedly arranged on one side of the front side plate 15 close to the rear side plate 16, and a rear bearing seat A63 and a rear bearing seat B67 are fixedly arranged on one side of the rear side plate 16 close to the front side plate 15; one end of the forward output shaft 36 is rotatably connected with a rear bearing seat A63 by adopting a rear bearing A64, and the other end thereof passes through a front bearing A62 arranged in a front bearing seat A61 and extends to the outer side of the front side plate 15; one end of the reverse output shaft 46 is rotatably connected to a rear bearing housing B67 using a rear bearing B68, and the other end thereof passes through a front bearing B66 installed in the front bearing housing B65 and extends to the outside of the front side plate 15. One end of the forward output shaft 36 extending out of the front side plate 15 is connected with the first load, one end of the reverse output shaft 46 extending out of the front side plate 15 is connected with the second load, and the rotor spindle 20 rotates forward and reverse in a YZ plane to respectively drive the first load and the second load to rotate forward in an XY plane, so that serial work of the double output shafts is realized.
Preferably, the rotor 21 is fixedly mounted on the rotor spindle 20, and the stator is composed of a stator a22 and a stator B23 which are fixedly mounted on the upper side plate 13 and the lower side plate 14, respectively, and are symmetrically distributed about the rotor spindle 20. The stator a22 and the stator B23 are composed of excitation windings, and are mainly used for establishing a main magnetic field, and the direction of the magnetic field can be changed by changing the current direction of direct current in the excitation windings, so that the switching between the forward rotation and the reverse rotation of the rotor spindle 20 is realized. The rotor 21 adopts another excitation winding, and an alternating current is passed through the inside of the rotor, so that the direction of the torque generated by the rotor 21 under the condition that the direction of the magnetic field of the main magnetic field is unchanged is kept unchanged, namely the rotor main shaft 20 continues to rotate in the same direction. If the external power source is ac, the power cord may be directly connected to the coil connection in the rotor 21; if the external power source is direct current, a brush and a segment are added to convert the external direct current into alternating current in the rotor 21, so that the direction of the torque generated by the rotor spindle 20 is kept unchanged.
Preferably, the forward worm gear transmission shaft 31 is sleeved with a one-way bearing A32, a forward driving shaft sleeve 33 is sleeved outside the one-way bearing A32, and a forward bevel gear 34 is fixedly sleeved on the forward driving shaft sleeve 33; the reverse worm gear transmission shaft 41 is sleeved with a one-way bearing B42, the outside of the one-way bearing B42 is sleeved with a reverse driving shaft sleeve 43, and a reverse bevel gear 44 is fixedly sleeved on the reverse driving shaft sleeve 43. The one-way bearing A32 enables the forward bevel gear 34 to synchronously drive the forward worm gear transmission shaft 31 sleeved in the inner ring to synchronously rotate when the forward bevel gear 34 rotates reversely in the XZ plane, and simultaneously enables the forward worm gear transmission shaft 31 to keep static when the forward bevel gear 34 rotates forward in the XZ plane, namely the forward bevel gear 34 idles around the forward worm gear transmission shaft 31 in the forward direction. The function of the one-way bearing B42 is similar to that of the one-way bearing a 32.
Preferably, the installed one-way bearing A32 and the one-way bearing B42 can generate positive idle rotation relative to the inner ring of the outer ring. When the drive bevel gear 24 rotates forward in the YZ plane, the forward bevel gear 34 rotates in reverse exactly in the XZ plane, and the reverse bevel gear 44 rotates in forward exactly in the XZ plane. Therefore, when the forward bevel gear 34 or the reverse bevel gear 44 rotates forward in the XZ plane, the corresponding forward worm-gear transmission shaft 31 or the reverse worm-gear transmission shaft 41 is stationary; when the forward bevel gear 34 or the reverse bevel gear 44 rotates reversely in the XZ plane, the corresponding forward worm gear transmission shaft 31 or the reverse worm gear transmission shaft 41 is driven to rotate reversely. The rotor spindle 20 rotates forward and backward in a YZ plane to respectively drive the first load and the second load to rotate forward in an XY plane, so that the serial work of the two output shafts is realized.
Preferably, the outer surface of the forward worm gear transmission shaft 31 is provided with a spiral groove a for accommodating a metal spiral spring a 37; the outer surface of the reverse worm wheel transmission shaft 41 is provided with a spiral groove B for accommodating a metal spiral spring B47; the cross sections of the spiral grooves a and B are trapezoidal, and the widths thereof are larger than the wire diameters of the metal coil springs a37 and B47. The spiral grooves a and B provide a space for axial deformation of the metal coil springs a37 and B47 to increase meshing flexibility of the forward worm wheel 35 and the reverse worm wheel 45; on the other hand, the occurrence of an excessive deformation amount can be prevented to ensure the engagement stability with the forward worm wheel 35 and the reverse worm wheel 45.
The working process of the invention is as follows: by controlling the direction of the current of the direct current in stator a22 and stator B23, the direction of rotation of the rotor spindle 20 can be controlled. Under the condition that the current directions in the stator A22 and the stator B23 are unchanged, alternating current or direct current is introduced into the rotor 21, and the direct current is converted into alternating current by utilizing the brushes and the commutator segments, so that the torque direction generated by the rotor 21 under the condition that the magnetic field direction of the main magnetic field is unchanged is kept unchanged, and further the rotor spindle 20 keeps constant forward rotation or reverse rotation in a YZ plane.
When the rotor spindle 20 rotates forward in a YZ plane, the drive bevel gear 24 drives the forward bevel gear 34 and the reverse bevel gear 44 to respectively rotate reversely and forward in an XZ plane, at this time, because the one-way bearing A32 and the one-way bearing B42 respectively belong to a 'stopping' state and a 'allowing' state, the forward bevel gear 34 drives the forward worm gear transmission shaft 31 to rotate reversely in the XZ plane, and the reverse bevel gear 44 drives the reverse drive shaft sleeve 43 to idle in a forward direction on the reverse worm gear transmission shaft 41; the forward worm wheel transmission shaft 31 rotates reversely, and flexibly engages with a forward worm wheel 35 through a metal spiral spring A37 wound on the forward worm wheel transmission shaft, so that a forward output shaft 36 is driven to rotate forward in an XY plane, and output of external rotation is realized; in the process, the reverse drive sleeve 43 idles with the reverse bevel gear 44, the reverse worm gear shaft 41 is stationary, and the reverse output shaft 46 is stationary. Thus, rotor spindle 20 rotates forward in the YZ plane, forward output shaft 36 rotates forward in the XY plane, and reverse output shaft 46 is stationary.
When the rotor spindle 20 rotates reversely in a YZ plane, the drive bevel gear 24 drives the forward bevel gear 34 and the reverse bevel gear 44 to respectively rotate forwardly and reversely in the XZ plane, at the moment, because the one-way bearing A32 and the one-way bearing B42 respectively belong to 'allowing' and 'stopping' states, the forward driving shaft sleeve 33 idles along with the forward bevel gear 34, the forward worm gear transmission shaft 31 is static, and the forward output shaft 36 is static; in the process, the reverse bevel gear 44 drives the reverse worm transmission shaft 41 to rotate reversely in the XZ plane, and the reverse worm transmission shaft 41 rotates reversely, and flexibly engages with the reverse worm gear 45 through the metal spiral spring B47 wound on the reverse worm transmission shaft, so as to drive the reverse output shaft 46 to rotate forward in the XY plane, and output of external rotation is realized. Thus, rotor shaft 20 rotates in reverse in the YZ plane, forward output shaft 36 is stationary, and reverse output shaft 46 rotates in forward in the XY plane.
The above is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through creative efforts should fall within the scope of the present invention.
