Abstract
The utility model provides a rotating shaft clutch of a mechanical toy. The utility model is characterized in that a rotating shaft [31] of non-round cross section is adopted; a movable shaft sleeve is matched with the rotating shaft of the non-round cross section through round holes to keep the rotation relation between the movable shaft sleeve and the rotating shaft; a fixing shaft sleeve [41] is matched with the rotating shaft through non-round holes of an interface which is crossed with a cylindrical surface having the same shaft with the rotating shaft; the fixing shaft sleeve moves along the rotating shaft direction and doesn't rotate along the rotating shaft. Because the relative movement can be done between the fixing shaft sleeve and the rotating shaft along a shaft line; the changes of the mesh and the demesh between two shaft couplings of the shaft sleeve are realized under the condition that the fixing shaft sleeve moves, but the position of the shaft direction is not moved. The performance of the rotating shaft clutch of mechanical toy provided by the utility model makes the rotating shaft which is connected with a crankshaft work stably; the work is more stable; because only the fixing shaft sleeve is moved, the resistance is small; the elasticity of a spring is smaller, and the power consumed by the mechanism is less.
Description
Technical field the utility model relates to a kind of rotating shaft clutch of mechanical toy.
The rotating shaft clutch of the mechanical toy that background technology the utility model is mentioned, be in mechanical toy, to do reversing and when clockwise when the gear in the rotating shaft is driven respectively, rotating shaft is by transmission with the mechanism of conversion between not by transmission, in order to produce the rotation in gap.The structure of the rotating shaft clutch of mechanical toy in the past is, rotating shaft has circular cross-section, having installed one in the rotating shaft does not make in relative rotation fixed hub with rotating shaft and has installed one and made movable in relative rotation axle sleeve with rotating shaft, wherein fixed hub is fixedlyed connected with rotating shaft, movable axis puts and is installed with and rotating shaft driven wheel meshed gears, can make axial float between rotating shaft and the frame, have a spring that fixed hub and movable axle sleeve are harmonious between fixed hub and the frame.On the end face that fixed hub and movable axle sleeve are harmonious, cylindrical cam and jaw and toothed coupling are arranged.When movable axle sleeve rotates, or cylindrical cam is pushed open fixed hub, shaft coupling breaks away from engagement and does not drive fixed hub, and rotating shaft is not rotated; Or push fixed hub to movable axle sleeve by spring, shaft coupling engagement and drive fixed hub is rotated rotating shaft.Owing to fixedly connected between the fixed hub in this structure and the rotating shaft, lean on the axial float between rotating shaft and the support and make shaft coupling between two axle sleeves do engagement and break away from variation between the engagement, therefore as when this rotating shaft is a bent axle, its play must influence the service behaviour of bent axle, need to strengthen the elastic force of spring simultaneously to overcome the resistance of driving member that bent axle is connected, the power that this rotating shaft clutch that has just increased mechanical toy is consumed.
Summary of the invention is at above-mentioned deficiency, and technical problem to be solved in the utility model is exactly to eliminate the axial float of rotating shaft when keeping required clutch action, thereby proposes a kind of rotating shaft clutch of new mechanical toy.
The rotating shaft clutch of mechanical toy provided by the utility model, has rotating shaft, movable axle sleeve and fixed hub are installed in the rotating shaft, its shaft is non-circular cross-section, the axis of rotating shaft is by the shape central point of noncircular cross section, movable axle sleeve cooperates with rotating shaft with circular hole, the diameter of circular hole is greater than the circumscribed circle diameter of rotating shaft on-circular cross-section, fixed hub cooperates with rotating shaft with non-circular hole, and the face of cylinder crossing contact-making surface coaxial with rotating shaft arranged between non-circular hole on the fixed hub and the rotating shaft.The contact-making surface that intersects with the face of cylinder between so-called non-circular hole and the rotating shaft, be meant (as the matched in clearance) of and the comprehensive engagement not necessarily similar of the profile of non-circular hole with the profile of rotating shaft on-circular cross-section projection on axis direction, but the line segment that contact is arranged between these two profiles, may be straightway or curved section, the line segment that intersects with the circle that with the shaft axis is the center of circle is arranged in the line segment that is contacted.Promptly in the contact-making surface between non-circular hole and rotating shaft, some is to intersect with the coaxial face of cylinder of rotating shaft.
The rotating shaft clutch of mechanical toy provided by the utility model, its shaft is the cylinder in regular polygon cross section, the axis of rotating shaft is by the circumscribed circle center of circle in regular polygon cross section, movable axle sleeve cooperates with rotating shaft with circular hole, the diameter of circular hole is greater than the circumscribed circle diameter in rotating shaft regular polygon cross section, fixed hub cooperates with rotating shaft with the regular polygon hole, the limit number in the limit number in the regular polygon hole of fixed hub and rotating shaft regular polygon cross section has the integral multiple relation, and circumscribed circle diameter circle in rotating shaft regular polygon cross section is between the circumscribed circle diameter and inscribed circle diameter in regular polygon hole on the fixed hub.The limit number in the regular polygon hole of so-called fixed hub and the limit number in rotating shaft regular polygon cross section have the integral multiple relation, are meant the former to be the latter's integral multiple or the integral multiple that the latter is the former.
The rotating shaft clutch of mechanical toy provided by the utility model, the shape of its shaft is to have the shape that groove constituted parallel with axis on the circular shaft, movable axle sleeve and fixed hub are all made matched in clearance with circular hole and rotating shaft, but the projection of inserting elongated slot in the rotating shaft is arranged on the circular hole of fixed hub.
The rotating shaft clutch of mechanical toy provided by the utility model, the on-circular cross-section of its shaft are installing and fixing axle sleeve and are existing on the length of doing displacement under the cam promotion at least.Promptly in rotating shaft, the part that fixed hub will move at work must be an on-circular cross-section, as comprises the non-circular of rule, as oval, just many than shape and irregular non-circular.
The rotating shaft clutch of mechanical toy provided by the utility model adopts the rotating shaft of on-circular cross-section, movable axle sleeve is cooperated the relation that relatively rotates between maintenance activity axle sleeve and the rotating shaft with the rotating shaft of on-circular cross-section with circular hole; And with fixed hub to cooperate between the non-circular hole of the contact-making surface that intersects with the coaxial face of cylinder of rotating shaft and the rotating shaft, make fixed hub move axially and can not rotate according to rotating shaft according to rotating shaft.When driving gear drives activity axle sleeve rotates, or cylindrical cam is pushed open fixed hub, shaft coupling breaks away from engagement and does not drive fixed hub, and rotating shaft is not rotated; Or push fixed hub to movable axle sleeve by spring, shaft coupling engagement and drive fixed hub is rotated rotating shaft.Because can relatively move according to axis between fixed hub and the rotating shaft, so can be in that fixed hub is moved realize engagement and out-of-gear variation between the two axle sleeve shaft couplings under the motionless situation of rotating shaft axial location.It is that work is more stable that the above-mentioned performance of the rotating shaft clutch of mechanical toy provided by the utility model makes rotating shaft be connected with bent axle, because of moving what promoted only is fixed hub, resistance is less, and the elastic force of spring also can be littler, and the power that this mechanism consumed is just less.
