The rotation speed change mechanism has the characteristics of compact structure, high stability and easy high-speed operation, and is easy to repair with fewer parts.
Description
Technical field
The utility model relates to a kind of rotation gear based on modular design.
Background technique
In the mechanical transmission controlling Design, in the time of making driven member by a special exercise regular movement, generally adopt cam mechanism to realize, yet traditional cam mechanism can only realize the straight moving or swing of cam follower.Therefore realize at the uniform velocity to rotate input motion through conjugate cam and change speed change rotation output movement into; Concerning the transmission control device design; Have certain degree of difficulty, this can increase greatly the internal structure complexity of whole transmission controlling mechanism, and it is too huge that the complicacy of internal structure then must cause whole driving mechanism to have a volume; Stability is not high, the shortcoming that is not easy to safeguard.
The model utility content
The purpose of the utility model has been to provide a kind of rotation gear based on modular design; Purpose is intended to convert coaxial speed change rotation output movement into at the uniform velocity rotating input motion; And the characteristic output at intermittence that can realize stopping-move-stop-move; Change different cams and can obtain different rotation output movements, become the rotation gear module in a kind of machine.
In order to achieve the above object, the technological scheme of the utility model is:
A kind of rotation gear based on modular design comprises motion input disk, cam mechanism, slide block, fork and output shaft and balance mass block; Wherein the balancing mass piece is fixedly mounted on the motion input disk; Wherein motion input disk and cam mechanism are hinged, cam mechanism and slide block active link, and slide block and fork are hinged, fork and output shaft fixed connection.
Described cam mechanism comprises a pair of conjugate cam and a rocking arm; 2 rollers are installed on the described rocking arm; Wherein a pair of conjugate cam and frame are connected, and one of them roller on the rocking arm and a conjugate cam flexibly connect, and another roller on the rocking arm and another conjugate cam flexibly connect.
Described rocking arm is hinged with motion input disk.
Be movably set with slide block in the chute on the described rocking arm.
The center of circle of described motion input disk and the center of circle of conjugate cam coincide.
The beneficial effect of the utility model is: the utility model purpose is intended to convert coaxial speed change rotation output movement into at the uniform velocity rotating input motion, and can realize that the characteristic at intermittence of stopping-move-stopping-moving exports.Have compact structure, stability is high, the characteristics that are easy to run up.And, make that whole rotation gear is easy to safeguard because component part is less.

Embodiment
A kind of rotation gear of present embodiment based on modular design, as shown in Figure 1; Comprise motion input disk 1, cam mechanism, slide block 4, fork 5, output shaft 7 and balance mass block 8; Wherein balancing mass piece 8 is fixedly mounted on the motion input disk 1, and motion input disk 1 is hinged with cam mechanism, cam mechanism and slide block 4 active links, and slide block 4 is hinged with fork 5, and fork 5 is connected with output shaft 7.Described cam mechanism comprises a pair of conjugate cam 6 and rocking arm 2; 2 rollers 3 are installed on the described rocking arm 2; Wherein a pair of conjugate cam 6 is connected with frame, and one of them roller 3 on the rocking arm 2 and a conjugate cam 6 flexibly connect, and another roller 3 on the rocking arm 2 flexibly connects with another conjugate cam 6.Described rocking arm 2 is hinged with motion input disk 1.Be movably set with slide block 4 in the chute on the described rocking arm 2.The center of circle of described motion input disk 1 and the center of circle of conjugate cam 6 coincide.
As shown in Figure 2, the movement mechanism of rotation gear, the angle of rotation of input is Φ; The angle that i.e. motion input disk 1 rotates; The angle of rotation of output is α, i.e. the rotation angle of fork 5, and both realize by the conversion of uniform motion to variable motion through the rotation gear.
As shown in Figure 3; In a cycle of motion; The total angle that the angle of rotation Φ of input and the angle of rotation α of output turn over is 360 °; Wherein the angle of rotation Φ of input does the uniform speed rotation, and the output angle then rotatablely moves by the input of the motion among Fig. 3 disk 1 angle and corresponding fork 5 output angle metrics rule accordingly.
As shown in Figure 4, in the process of transmission, a pair of conjugate cam 6 is fixed on the frame; Motion input disk 1 is done the uniform speed rotation around O1 point, and the articulating point O2 of rocking arm 2 is installed on the motion input disk 1, along with the rotation of motion input disk 1 is turned round; a chute is arranged on the rocking arm 2; slide block 4 can be in the enterprising line slip of chute, and the motion through slide block 4 passes to fork 5 with the characteristics of motion, thereby the speed change rotation that realizes output shaft 7 is exported.
Conjugate cam rotation gear is the combination of a kind of conjugate cam mechanism and slide block slotted link mechanism, and the employing of conjugate cam has reduced driving force greatly, has improved transmission efficiency.Owing in the present embodiment balancing mass piece 8 has been installed, adopt Symmetric Mass to arrange with rocking arm 2, can reduce the inertial force that whole driving mechanism produces in the rotary course to a great extent.
