Embodiment Construction

[0050] Necessary explanation: In the main text of this manual and all the drawings, the same or similar components and their characteristic parts use the same symbols, and they will only be explained in detail when they appear for the first time, and will not be repeated when they appear again. Give repeated elaboration.

[0051] Figures 1 to 5 show the first embodiment of the present invention, which has the most typical structure of a spring steel ball safety clutch. As shown in FIG. 1, the fixed joint element 50 is sleeved on the outer cylindrical surface of the unthreaded end of the second sleeve 206 by one end of the steel ball hub 80, and is axially fixed by the snap ring 210. The second sleeve 206 and the steel ball hub 80 are made into a rigid body, as shown in FIG. 2. The blocking ring 100 is placed in the circular cavity of the fitting end of the fixing joint element 50. The restraining spring 120 is installed between the blocking ring 100 and the steel ball hub 80 to fo...

Abstract

The present invention discloses a no-collision spring steel ball safety clutch, which has the characteristics of no overload impact or no collision, high rotating speed, simplicity and reliability, easy manufacture, and long service life. The present invention is characterized in that the no-collision spring steel ball safety clutch is provided with a blocking embedding mechanism preventing a steel ball embedding mechanism from being embedded under the overload condition, the mechanism on the axial direction is positioned in the steel ball embedding mechanism, and the mechanism on the radial direction is positioned in the steel ball embedding mechanism or outside the steel ball embedding mechanism; a lift angle of both sides blocking the working surface is formed to enough ensure the friction self-locking collided on the both sides and the stability of the blocking operating condition, in order that the lift angle has the capabilities that the adaptive axle base is changed and the abrasion is automatically compensated; no collision characteristic of the overrunning operating condition of the two embedding mechanisms, and the separating block of the blocking embedding mechanism and the absolute reliability of the embedding return process are maintained for a long time. After the overload separation, the positive rotation or negative rotation which is simple and convenient can evenly realize the embedment replacement of the clutch automatically.

Description

Technical field [0001] The invention relates to a clutch device in the field of mechanical transmission, in particular to a spring steel ball safety clutch device with a torsion limit and stop function. technical background [0002] In the prior art, the axial spring steel ball safety clutch replaces the fixed and integrated inlays with independent steel balls that can rotate flexibly, thereby improving the sensitivity and working speed of the embedded safety clutch. However, due to repeated collisions after overload, harmful impacts on the transmission shaft system and harmful wear on the steel ball grooves are caused. Therefore, the sensitivity and life of the clutch are affected, and its working speed is also greatly restricted. At a working torque of the order of 1,000N·m, the maximum working speed generally does not exceed 400 rpm. At the same time, its maximum working torque is therefore limited. Summary of the invention [0003] The purpose of the present invention is to ...
