Description

A kind of mechanism of steel ball transmitting torque

Technical field

The utility model relates to a kind of mechanism of steel ball transmitting torque.

Background technique

Present transmitting torque mechanism complex structure mostly, inconvenient operation move not steadily, and noise is big, and is rapid inadequately in conjunction with separation, and working life is shorter.

The model utility content

The utility model purpose is to provide a kind of mechanism of steel ball transmitting torque, and working life is long, operation is more steady, and rapider in conjunction with separating.

To achieve these goals, the utility model adopts following technological scheme: a kind of mechanism of steel ball transmitting torque, comprise with being set on the main shaft of being in transmission connection of external power supply and can rotate freely driving wheel, the output gear that is used for outputting power is connected with spindle, driving wheel one side is provided with the driven wheel that can vertically move meshing with main shaft, the driven wheel side is provided with small ball, be provided with pit with corresponding part, small ball position on the driving wheel side, be provided with in the main shaft driven wheel is moved and driving wheel crimping or the push-pull mechanism that separates vertically.

Be provided with elastic washer between described driven wheel and the driving wheel.

Described pit is a cone shape hole.

Described driven wheel side is provided with two small balls at least, the also corresponding pit that same number is set of driving wheel.

Described push-pull mechanism comprises center push rod and handle.

Simple in structure, the long service life of the utility model is adjusted and overhauled convenient, good manufacturability, and is simple to operation; In conjunction with separating rapidly, the running accuracy height moves steadily, and noise is low.

Embodiment

Embodiment: as Figure 1-3, a kind of mechanism of steel ball transmitting torque comprises driving wheel 9 that is in transmission connection with external power supply and the output gear 4 that is used for outputting power, driving wheel 9 is set on the main shaft 18 and can rotates freely, and corresponding position is equipped with to be embedded in hole and the hole and drives steel ball 16 on the axle sleeve of output gear 4 and on the main shaft 18.Driving wheel 9 one sides are provided with the driven wheel 7 that can vertically move meshing with main shaft 18, be provided with elastic washer 8 between driven wheel 7 and the driving wheel 9, driven wheel 7 sides are provided with two small balls 11 at least, the small ball 11 of two or more numbers promptly can be set, for better in conjunction with effect, can be provided with the pit of same number on driving wheel 9 sides with corresponding part, small ball 11 position along all small balls 11 evenly are set on the same circumference, the pit in the present embodiment is a cone shape hole 17.Be provided with in the main shaft 18 driven wheel 7 is moved and driving wheel 9 crimping or the push-pull mechanism that separates vertically.

Push-pull mechanism in the present embodiment comprises the center push rod 6 that is arranged in the main shaft 18, the outer end of center push rod 6 is provided with handle 1 and handle fixed cover 2, center push rod 6 is provided with the projection 13 of the inner small and outside big shape conical surface, the corresponding position is provided with and is provided with big steel ball 12 in perforate and the perforate on the main shaft 18, at least two big steel balls 12 along the circumferential direction are set, and the axle sleeve outer end of driven wheel 7 and big steel ball 12 corresponding positions are provided with inner small and outside big taper hole; Be provided with pressure spring 5 between the projection 13 of center push rod 6 and the main shaft of outer end, handle 1 and handle fixed cover 2 are provided with the center push rod positioning means, promptly on handle 1 circumference, be provided with positioning convex 21, be fixed in and be respectively equipped with shallow slot shape on the exterior edge face of the handle fixed cover 2 on the support 3 and separate locating notch 19 and deep trouth shape, and the axial length of the projection 13 on the axial distance of two breach and the center push rod 6 is suitable in conjunction with locating notch 20.

Certainly push-pull mechanism is not limited only to above-mentioned structure, and other can make driven wheel 7 move vertically with driving wheel 9 crimping or the push-pull configuration that separates and all can use.

Be provided with position-limit mechanism between center push rod 6 the inners and the main shaft, promptly be provided with limited impression 14 vertically in center push rod 6 the inners, main shaft 18 is provided with projection 15, and projection 15 is embedded forms position-limit mechanism in the limited impression 14 of center push rod 6.Be provided with between the inner of center push rod 6 and the main shaft 18 and adjust nut 10.

The process that clutch in the present embodiment closes: rotating pull handle 1, make positioning convex 21 and the handle fixed cover 2 corresponding in conjunction with locating notch 20 positions, unclamp handle 1 then, center push rod 6 moves under the effect of pressure spring 5 to the inside, the projection 13 inner small and outside big shape conical surfaces on the center push rod 6 promote big steel ball 12, make big steel ball 12 along the radially outward side shifting, promote the inner small and outside big taper hole in axle sleeve outer end of driven wheel 7, thereby promote driven wheel 7 along axially moving to the inside, make driven wheel 7 and driving wheel 9 compression fit, small ball 11 on the driven wheel 7 enters in the cone shape hole 17 on the driving wheel 9, thereby driven wheel 7 rotates synchronously with driving wheel 9.

The process that clutch in the present embodiment divides: pulling handle 1 overcomes the strength and the rotation of pressure spring 5 laterally, make positioning convex 21 and handle fixed cover 2 to separate locating notch 19 positions corresponding, unclamp handle 1 then, center push rod 6 moves laterally, projection 13 on the center push rod 6 staggers with big steel ball 12, make big steel ball 12 radially move to the inside, the inner small and outside big taper hole in axle sleeve outer end of driven wheel 7 has lost stopping of big steel ball 12, driven wheel 7 moves laterally vertically under the effect of shell fragment 8 and separates with driving wheel 9, small ball 11 and the cone shape hole on the driving wheel 17 on the driven wheel 7 break away from, and have realized that driven wheel 7 separates with driving wheel 9.
