A torque conversion device

Abstract

The invention discloses a torque conversion device, which relates to the field of mechanical technology, and includes an end cover, wherein a bearing seat is arranged on the top of the end cover. When the first gear of the invention rotates clockwise, the fourth gear meshing with the first gear is counterclockwise idling, and since the clockwise rotation of the first gear drives the second gear to rotate counterclockwise, the counterclockwise rotating second gear drives the third gear to rotate clockwise, and since a one-way bearing is arranged between the third gear, the fourth gear and the third transmission shaft, the third transmission shaft is driven to rotate. When the first transmission shaft is rotated counterclockwise, the fourth gear drives the third transmission shaft to rotate clockwise through the one-way bearing, the third gear becomes counterclockwise idling, and the third transmission shaft continues to rotate clockwise. By inputting forces in different rotation directions, the output is all rotation forces in the same direction, which is more convenient for the staff to operate and greatly improves the work efficiency.

[0002] Torque is a physical quantity that represents the rotational effect produced when a force acts on an object. The product of force and the lever arm is torque. Torque is a vector. The magnitude of the torque of a force on a certain point is the length of the perpendicular line from the point to the line of action of the force multiplied by the magnitude of the force. Its direction is perpendicular to the plane formed by the perpendicular line and the force and is determined by the right-hand screw rule. The magnitude of the torque of a force on a certain axis is equal to the projection of the torque of the force on any point on the axis onto the axis.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1-3A torque conversion device comprises an end cover 1, a bearing seat 2 is arranged on the top of the end cover 1, a first transmission shaft 3 rotatably connected to the bearing seat 2 is arranged on one side of the top of the end cover 1, a third transmission shaft 7 rotatably connected to the bearing seat 2 is arranged on the other side of the top of the end cover 1, a second transmission shaft 5 rotatably connected to the bearing seat 2 is arranged at one end of the top of the end cover 1, a first gear 4 is fixedly connected to the outer side of the first transmission shaft 3 at the middle position, a second gear 6 is fixedly connected to the outer side of the second transmission shaft 5 at the oblique upper part of the first gear 4, a third gear 8 and a fourth gear 10 are respectively arranged on the top and bottom of the third transmission shaft 7, and a one-way bearing 9 is rotatably connected between the third gear 8 and the fourth gear 10 and the third transmission shaft 7, the first gear 4 is respectively meshed with the second gear 6 and the fourth gear 10, and the second gear 6 is meshed with the third gear 8.

[0017] When the first transmission shaft 3 drives the first gear 4 to rotate clockwise, the fourth gear 10 meshing with the first gear 4 is counterclockwise idling, and since the first gear 4 rotates clockwise and drives the second gear 6 to rotate counterclockwise, the counterclockwise rotating second gear 6 drives the third gear 8 to rotate clockwise, and since a one-way bearing 9 is provided between the third gear 8, the fourth gear 10 and the third transmission shaft 7, when the third gear 8 rotates clockwise, it drives the third transmission shaft 7 to rotate. When the first transmission shaft 3 rotates counterclockwise, the fourth gear 10 drives the third transmission shaft 7 to rotate clockwise through the one-way bearing 9. At this time, the third gear 8 becomes counterclockwise idling, so the third transmission shaft 7 continues to rotate clockwise. By inputting forces in different rotation directions, the output is all rotation forces in the same direction, which greatly improves the work efficiency.

[0018] Please refer to Figure 1 and Figure 2 The number of the bearing seats 2 is three, and the bearing seats 2 are in the form of an equilateral triangle. The present invention arranges the three groups of bearing seats 2 in the form of an equilateral triangle, so that the gears can mesh with each other more tightly.

[0019] Please refer to Figure 1 and Figure 2 The bottom of the end cover 1 is provided with threaded holes 11, and the number of the threaded holes 11 is four groups. By providing four groups of threaded holes 11, the present invention can connect the end cover 1 with other equipment, which is more convenient.

[0020] Please refer to Figure 1 and Figure 3 The top ends of the first transmission shaft 3, the second transmission shaft 5 and the third transmission shaft 7 are all fixedly connected with support rings 12, and rubber rings are arranged on the outside of the support rings 12. By arranging the support rings 12, the present invention makes the stability of the transmission shaft better.

[0021] Please refer to Figure 1A keyway 13 is provided at one end of the first transmission shaft 3 between the first gear 4 and the support ring 12, and an anti-slip pattern is provided inside the keyway 13. By providing the keyway 13, the present invention can connect the first transmission shaft 3 with external equipment, and provide the anti-slip pattern to increase the friction force during cooperation.

[0022] Working principle: when in use, the three groups of transmission shafts of the present invention are all fixed on the end cover through the bearing seat 2, the first transmission shaft 3 and the first gear 4 are fixedly connected, the second transmission shaft 5 and the second gear 6 are fixedly connected, and the third transmission shaft 7 and the third gear 8 and the fourth gear 10 are rotatably connected through the one-way bearing 9. When the first transmission shaft 3 rotates clockwise, the first gear 4 also rotates clockwise, and the lower end of the first gear 4 is meshed and connected with the fourth gear 10. At this time, the fourth gear rotates counterclockwise. Since a one-way bearing 9 is provided between the fourth gear 10 and the third transmission shaft 7, the fourth gear 10 rotates idly and will not drive the third transmission shaft 7 to rotate counterclockwise. At the same time, the upper end of the clockwise rotating first gear 4 drives the second gear 6 to rotate counterclockwise, and the second gear 6 drives the third gear 8 to rotate clockwise. Due to the effect of the one-way bearing 9, the clockwise rotation of the third gear 8 can drive the clockwise rotation of the third transmission shaft 7. When the first transmission shaft 3 rotates counterclockwise, the first The gear 4 also rotates counterclockwise, and the first gear 4 drives the fourth gear 10 to rotate clockwise. Due to the effect of the one-way bearing 9, the fourth gear 10 rotating clockwise can drive the third transmission shaft 7 to rotate clockwise. At the same time, the counterclockwise rotating first gear 4 drives the second gear 6 to rotate clockwise, and the clockwise rotating second gear 6 drives the third gear 8 to rotate counterclockwise. Since a one-way bearing 9 is arranged between the third gear 8 and the third transmission shaft 7, the third gear 8 rotates idly. Through the ingenious use of the one-way bearing 9, different input directions can be achieved, and uninterrupted rotational motion in the same direction can be obtained. The one-way bearing is a bearing that can rotate freely in one direction and is locked in another direction. Therefore, when the staff uses the present invention to operate, no matter it rotates clockwise or counterclockwise, the output shaft can rotate in the same direction, which is more labor-saving to operate, greatly improves the work efficiency of the staff, and is more convenient.
