The input shaft and the first transmission shaft are only distinguished in name, when the device is used, the first transmission shaft can be used as power input, the outer ring of the internal gear or the input shaft can be used as power output, the change of the speed ratio is completed through the change of the included angle between the first transmission shaft and the axis of the internal gear, the input shaft is used as power input subsequently, and the first transmission shaft or the shaft system which is further connected with the first transmission shaft is used as power output for example analysis:
due to the existence of the circular arc teeth, even if the first transmission shaft and the axis of the internal gear form an included angle theta, effective meshing can still be completed at the contact part, and if the number of the circles meshed with the internal gear on the first transmission shaft and the input shaft is the same, namely the transmission ratios of the first transmission shaft and the input shaft to the internal gear are respectively the same, the total transmission ratio is only related to the theta.
Furthermore, the continuously variable transmission further comprises a second transmission shaft, a third transmission shaft, a universal coupling and an output shaft, the output shaft is rotatably supported through a bearing, the second transmission shaft and the third transmission shaft are connected together through the universal coupling, the other end of the second transmission shaft is in transmission connection with the sliding sleeve at one end of the first transmission shaft, and the other end of the third transmission shaft is in transmission connection with the sliding sleeve at one end of the output shaft.
The first transmission shaft needs to rotate due to a speed change principle, so that the uniform arrangement of an output structure is not facilitated, if the first transmission shaft is directly used as an output shaft, the output position of the first transmission shaft can be changed according to the speed change requirement of slip, and the shaft connection outside is not facilitated; the end of the first transmission shaft is drawn by an arc line, the circle center of the arc is located at the circle center of the arc tooth on the rotating plane of the first transmission shaft, the invention leads the power to the output shaft through the second transmission shaft and the third transmission shaft to carry out the power output with fixed position,
the realization principle is as follows: the tip and the second transmission shaft sliding connection of first transmission shaft and carry out the transmission, first transmission shaft rotation adds the rotation around circular arc tooth centre of a circle position, second transmission shaft and third transmission shaft link together through universal joint, the second transmission shaft is also the rotation and adds the wave, but it waves centre of a circle (universal joint department) and only carries out rectilinear movement, the rotary motion of first transmission shaft is under the rotary motion's of third transmission epaxial rotary motion's of conversion flow, the third transmission shaft is except that the rotation, only carry out along the axial slip of output shaft, and the output shaft only carries out the rotation, so set up down, the one end that the third transmission shaft was kept away from to the output shaft is position-fixing, thereby make things convenient for the external world to connect.
Furthermore, the continuously variable transmission also comprises a corner structure, the corner structure is connected to the first transmission shaft, and the corner structure is used for changing the axial line included angle between the first transmission shaft and the internal gear;
the corner structure comprises a corner matching rod, connecting rods, self-aligning ball bearings and a mounting seat, the middle part of the corner matching rod is rotatably mounted on the mounting seat, the rotation axis of the corner matching rod is perpendicular to the axis of the internal gear, the connecting rods are hinged to two ends of the corner matching rod, the first transmission shaft of the self-aligning ball bearing hoop sleeve is arranged at the other end of each of the two connecting rods, and the length parts of the first transmission shaft among the corner matching rod, the connecting rods and the two self-aligning ball bearings form a parallelogram structure. Because the first transmission shaft needs to be meshed with the inner gear, on the plane of the parallelogram, the connecting line of the rotating axis of the angle matching rod and the circular arc tooth is parallel to the connecting rod.
The first transmission shaft needs to rotate by a corresponding angle to adjust the speed ratio, and the rotary support of the first transmission shaft needs to change the position correspondingly while adjusting the angle so as to ensure that the structure is complete.
Preferably, the sliding sleeve transmission connection of the first transmission shaft and the second transmission shaft is a sliding spline connection, and the sliding sleeve transmission connection of the third transmission shaft and the output shaft is a sliding spline connection. The spline structure is a reliable transmission structure and can be easily operated by sliding, but a single-key structure may be used instead, but the speed shock resistance performance in the stability of the transmission may be somewhat lowered.
The third transmission shaft is also slidably supported in its axial direction by a linear bearing. Originally, the output shaft has been possessed along its axial bearing support, however, the third transmission shaft has not carried out the axial support yet, and under this condition, if the load is great, the rotary motion that the second transmission shaft transmitted through universal joint has great component force rather than axial and becomes the contained angle, can influence the third transmission shaft at the slippage of output shaft tip, destroys transmission stability, so, supports the third transmission shaft through linear bearing, builds good axial slip environment for it.
Further, the rotation drive of the angle matching rod is provided with a self-locking structure. The final speed ratio is directly influenced by the angle of the angle matching rod, so that if the angle of the angle matching rod is subjected to vibration deviation, the operation of the whole system is influenced, and therefore, an angle locking structure is arranged at the corresponding angle rotation driving position of the angle matching rod, and the change of the angle in the operation process is prevented after the angle is adjusted.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a gear type slip continuously variable transmission comprises an internal gear 1, a first transmission shaft 2 and an input shaft 6, wherein an outer ring of the internal gear 1 is rotatably supported through a bearing, the internal gear 1 comprises circular arc teeth 11 arranged on an inner ring, the first transmission shaft 2 and the input shaft 6 are respectively provided with outer ring teeth meshed with the circular arc teeth 11 on a shaft body, and an alternating angle can be generated between the axis of at least one of the first transmission shaft 2 and the input shaft 6 and the axis of the internal gear 1.
Input shaft 6 and first transmission shaft 2 are the distinction in the name, when using the infrastructure when fig. 1, also can be that first transmission shaft 2 is as power input, let 1 outer lane of internal gear or input shaft 6 be power output, the change of speed ratio is accomplished through the change of first transmission shaft 2 and 1 axis contained angle of internal gear, follow-up all takes input shaft 6 as power input, let first transmission shaft 2 or the shafting of following further connection analyze as power output for the example:
as shown in fig. 2 and 3, due to the circular arc teeth 11, even if the first transmission shaft 2 and the internal gear 1 have an included angle θ, effective meshing can still be completed at the contact position, power with an angular speed of w0 is input to the input shaft 6, then according to the meshing process with the complete parallel axis of the internal gear 1, the transmission ratio is set to be p1, the angular speed of the internal gear 1 is w0 p1, the projection speed w2= w1 cos θ = w0 p1 cos θ of the complete internal gear 1 on the plane perpendicular to the first transmission shaft 2, and the transmission ratio of the internal gear 1 and the first transmission shaft 2 which are transmitted through the standard parallel axis is set to be p 2:
w3=w2/p2=w1*cosθ/p2= w0*p1*cosθ/p2，
if the number of teeth on the first transmission shaft 2 and the input shaft 6 is the same as that of the ring gear 1, i.e. p1= p2, then w3= w0 × cos θ, and by changing the value of θ, the total transmission ratio w3/w0 can be changed accordingly, and the change can be continuously changed along with the change of θ.
As shown in fig. 4, the continuously variable transmission further includes a second transmission shaft 41, a third transmission shaft 42, a universal coupling 43, and an output shaft 5, the output shaft 5 is rotatably supported by a bearing, the second transmission shaft 41 and the third transmission shaft 42 are connected together by the universal coupling 43, the other end of the second transmission shaft 41 is in transmission connection with one end of the first transmission shaft 2 by a sliding sleeve, and the other end of the third transmission shaft 42 is in transmission connection with one end of the output shaft 5 by a sliding sleeve.
The first transmission shaft 2 needs to rotate due to a speed change principle, so that the uniform arrangement of an output structure is not facilitated, if the first transmission shaft 2 is directly used as an output shaft, the output position of the first transmission shaft can be changed according to the speed change requirement of slip, and the shaft connection outside is not facilitated; the end of the first transmission shaft 2 draws an arc line, the circle center of the arc is located at the circle center of the arc tooth 11 on the rotation plane of the first transmission shaft 2, the invention leads the power to the output shaft 5 through the second transmission shaft 41 and the third transmission shaft 42 to carry out the power output with fixed position,
the realization principle is as follows: the end part of the first transmission shaft 2 is connected with the second transmission shaft 41 in a sliding mode and transmits, the rotation of the first transmission shaft 2 is added with the rotation around the circle center position of the circular arc tooth 11, the second transmission shaft 41 is connected with the third transmission shaft 42 through the universal coupling 43, the second transmission shaft 41 also rotates and shakes, but the shaking circle center (the position of the universal coupling 43) only moves linearly, the rotary motion of the first transmission shaft 2 is converted into the rotary motion on the third transmission shaft 42, the third transmission shaft 42 only slides along the axial direction of the output shaft 5 except for the rotation, and the output shaft 5 only rotates.
As shown in fig. 4, the continuously variable transmission further includes a corner structure, the corner structure is connected to the first transmission shaft 2, and the corner structure is used for changing an axial angle between the first transmission shaft 2 and the internal gear 1;
the corner structure comprises a corner matching rod 31, connecting rods 32, self-aligning ball bearings 33 and a mounting seat 34, the middle part of the corner matching rod 31 is rotatably mounted on the mounting seat 34, the rotation axis of the corner matching rod 31 is perpendicular to the axis of the internal gear 1, the connecting rods 32 are hinged to two ends of the corner matching rod 31, the self-aligning ball bearings 33 are arranged at the other ends of the two connecting rods 32 to hoop the first transmission shaft 2, and the length parts of the first transmission shaft 2 among the corner matching rod 31, the connecting rods 32 and the two self-aligning ball bearings 33 form a parallelogram structure. Since the first transmission shaft 2 needs to be meshed with the internal gear 1, on the plane of the parallelogram, the connecting line between the rotation axis of the angle matching rod 31 and the circular arc teeth should be parallel to the connecting rod 32, and the reaction is horizontal in fig. 4.
The first transmission shaft 2 needs to rotate by a corresponding angle to adjust the speed ratio, and the rotary support of the first transmission shaft 2 needs to change the position correspondingly while adjusting the angle so as to complete the structure. The angle B is greater than a, so the sliding connection of the first transmission shaft 2 with the second transmission shaft 41 is deeper, and the sliding connection of the third transmission shaft 42 with the output shaft 5 is shallower.
The sliding sleeve transmission connection of the first transmission shaft 2 and the second transmission shaft 41 is a sliding spline connection, and the sliding sleeve transmission connection of the third transmission shaft 42 and the output shaft 5 is a sliding spline connection. The spline structure is a reliable transmission structure and can be easily operated by sliding, but a single-key structure may be used instead, but the speed shock resistance performance in the stability of the transmission may be somewhat lowered.
As shown in fig. 4, the third transmission shaft 42 is also slidably supported in its axial direction by a linear bearing 44. In the case where the output shaft 5 has been provided with the bearing support in the axial direction, but the third transmission shaft 42 has not been axially supported, if the load is large, the rotational motion of the second transmission shaft 41 transmitted through the universal coupling 43 has a component force at a large angle with the axial direction, which affects the sliding of the third transmission shaft 42 at the end of the output shaft 5 and deteriorates the transmission stability, so that the third transmission shaft 42 is supported by the linear bearing 44 to create a good axial sliding environment.
The rotation of the angle lever 31 is driven with a self-locking structure. The angle of the angle matching rod 31 directly affects the final speed ratio, so if the angle of the angle matching rod 31 is subjected to vibration deviation, the operation of the whole system is affected, and therefore, an angle locking structure should be arranged at the corresponding angle rotation driving position of the angle matching rod 31 to prevent the angle change in the operation process after the angle is adjusted.
The rotation drive of the angle matching rod 31 is a worm gear and worm structure, the angle matching rod 31 is fixed with the worm gear, and the rotation power used for adjusting the angle drive of the angle matching rod 31 is loaded on the worm. The worm gear and worm structure is a reliable mechanical self-locking structure, can be used for ensuring the one-way transmission of angle driving power, can only change the angle of the angle matching rod 31 through the worm, and after the rotating power of the worm is removed, the angle matching rod 31 can not change the angle due to vibration.
The main operation process of the device is as follows: the rotation is input into the speed changer through the input shaft, the inner gear 1 is driven to rotate, the included angle between the axes of the inner gear 1 and the first transmission shaft 2 generates speed proportion change, the angle adjustment of the first transmission rod 2 is carried out through the angle matching rod 31, the stepless speed regulation characteristic is provided in a certain range, when the included angle theta is overlarge, the meshing degree of the first transmission shaft 2 and the inner gear 1 can be influenced effectively, the probability of vibration impact is increased, therefore, the speed changer can carry out corresponding operation tests according to the manufacturing precision and the tooth trimming of the circular tooth 11, a stable and reliable regulation range is determined, the speed changer can obtain stepless speed change capability in a large range by combining the grading speed regulation of the traditional gear box, the rotation of the first transmission shaft 2 is transmitted out through the second transmission shaft 41, the universal coupling 43, the third transmission shaft 42 and the output shaft 5 in sequence, the output position of the output shaft 5 is kept unchanged, the shafting connection is convenient for the outside.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
