Abstract
The utility model provides a three tangential keys type shaft coupling, belonging to a shaft coupling. In the utility model, three tangential keys are arranged respectively between a left flange plate and a left transmission shaft and between a right flange plate and a right transmission shaft; and the tangential keys are arranged on the cross-section of the transmission shaft in the following way: each end through the axis center of 180 degrees is provided with one tangential key in the same direction; and the other tangential key is arranged at the end through the axis center vertical to two connecting lines. The three tangential keys type shaft coupling has the advantages of simple and compact structure, large transferred torque, strong impact resistance and strong overloading performance, capability of transferring greater positive-rotation torque and less reverse-rotation torque, high transmission precision, stable performance and long service life.
Description
Technical field
The utility model relates to coupling.
Background technique
At present, the coupling on the market is singly-bound or two key and connects, and cause can not satisfy the big torque of effective transmission, impact is strong, load variations is violent, transmit the square of just walking around greater than problems such as the torques of reversing.Satisfy the axle with spool be connected, though connecting means now is more, and pluses and minuses are arranged respectively, the general pair keys that adopt connect, but because the machining error of keyway is difficult to guarantee cooperating between key and the keyway, produce relative movement between transmission shaft and the coupling flange dish and make, two key coupling shaft keyway easy deformation lost efficacy, do not have two keys during transmitting torque and connect the effect of transmitting torque, and be difficult to guarantee the working life of transmission shaft.
Summary of the invention
The purpose of this utility model just provides the big torque of a kind of transmission, the three tangent key formula coupling that impact resistance is strong.
The solution that realizes the utility model purpose is to comprise left flange plate 3, right flange plate 7, right transmission shaft 8, Left Drive axle 1, connecting bolt 6, spherical washer 4, flexible sheet 5, it is characterized in that between left flange plate 3 and the Left Drive axle 1, be respectively equipped with three tangent key 9 between right flange plate 7 and the right transmission shaft 8.
Tangent key 9 arranging on the transmission shaft cross section is: respectively arrange one crossing axle center 180 degree two ends are equidirectional, another is arranged crossing the end vertical with these two lines, axle center.
The utility model has the advantages that simple in structure, compactness, transmitting torque is big, shock resistance and overload are strong, transmits the square of just walking around greater than counter-rotating torque, transmission accuracy height, stable performance, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: 1-Left Drive axle; The 2-positioning screwn; The 3-left flange plate; The 4-spherical washer; The 5-flexible sheet; The 6-connecting bolt; The right flange plate of 7-; The right transmission shaft of 8-; The 9-tangent key.
Embodiment
In the center hole of left flange plate 3, Left Drive axle 1 is installed by tangent key 9, in the center hole of right flange plate 7, right transmission shaft 8 is installed by tangent key 9, between left flange plate 3 and the right flange plate 7 flexible sheet 5 is installed, connecting bolt 6 is by spherical washer 4, left flange plate 3 and right flange plate 7 are fixed together, and positioning screwn 2 is to be used for fixing flange plate and transmission shaft is axially movable.
Between left flange plate 3 and the Left Drive axle 1, be respectively equipped with three tangent key 9 between right flange plate 7 and the right transmission shaft 8.
Tangent key 9 arranging as shown in Figure 2 on the transmission shaft cross section: respectively arrange one crossing axle center 180 degree two ends are equidirectional, another is arranged crossing the end vertical with these two lines, axle center.That is to say that on the transmission shaft cross section, tangent key 9 are placed one at 9 position clockwise directions, 3 inverse position clockwises are placed one, and 6 inverse position clockwises are placed one.
The utility model adopts tangent key 9 to cooperate, making its tangent key upper and lower surface is working surface, can be when just changeing transmitting torque greater than characteristics such as counter-rotating torques, when then just changeing (clockwise) transmitting torque, wherein two tangent key 9 working surfaces pass through shaft axis, make of the tangential effect of two pressure on the working surface, can transmit very big torque along axle.And when transmitting oppositely (counterclockwise) torque, then have tangent key 9 working surfaces to pass through shaft axis owing to transmitting torque is smaller.Can transmit required less torque.Thereby realize effective connection of two transmission shafts.
Claims (2)
1. tangent key formula coupling, comprise left flange plate (3), right flange plate (7), right transmission shaft (8), Left Drive axle (1), connecting bolt (6), spherical washer (4), flexible sheet (5) is characterized in that being respectively equipped with three tangent key (9) between right flange plate (7) and the right transmission shaft (8) between left flange plate (3) and the Left Drive axle (1).
2. according to the said three tangent key formula coupling of claim 1, it is characterized in that tangent key (9) arranging on the transmission shaft cross section is: respectively arrange one crossing axle center 180 degree two ends are equidirectional, another is arranged crossing the end vertical with these two lines, axle center.
