Abstract
The invention relates to a directional circle type clutch, which comprises a clutch shaft, wherein the clutch shaft is provided with a radial-through axial key groove; two clutch keys are in clearance fit in the key groove; the upper ends of the clutch keys are inclined planes, and the inclined planes of the two clutch keys are arranged in parallel; a spring is arranged between the two clutch keys; the summation of the radial maximum heights of the two clutch keys is smaller than the height of the key groove when the spring is compressed; the clutch shaft is in clearance fit in a shaft hole of a clutch sleeve; two centrosymmetrical square grooves are formed on the shaft hole of the clutch sleeve; the width of the square grooves is smaller than that of the key groove; and one groove wall of the square grooves and one groove wall of the key groove are in the same plane. The directional circle type clutch has a compact structure, is safe and reliable, overcomes the defect that the conventional clutch occupies a large spatial position, and is convenient to operate.
Description
Technical field
The present invention relates to switch and circuit breaker, specifically a kind of switch and circuit breaker are with the directed circumference formula arrangement of clutch of motor-operating mechanism.
Background technology
Be provided with arrangement of clutch in the motor-operating mechanism of switch and circuit breaker.The effect of arrangement of clutch is when motor damages or have a power failure, and separates motor through manual handle, promotes the combined floodgate and the separating brake of circuit breaker or switch.Existing arrangement of clutch is through adding a long depression bar gear in two pitch wheels to be applied pressure up or down, makes two pitch wheels realize separating.The shortcoming of this arrangement of clutch is to make perpendicular bisector direction at gear, and the shared volume of motor-operating mechanism is excessive, and this contradicts with the volume compact that circuit breaker that is motor-operating mechanism are at present pursued.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of directed circumference formula arrangement of clutch is provided, this device volume is little, separates reliable and secure.
According to technical scheme of the present invention: a kind of directed circumference formula arrangement of clutch; Comprise clutch shaft, have the axial keyway that radially connects on the said clutch shaft, said keyway internal clearance is combined with two clutch key; The upper surface of said clutch key is the inclined-plane; The inclined-plane of two clutch key laterally arranges, and is provided with spring between two clutch key, the radially maximum height of two clutch key and less than the height of said keyway during said length of spring compressed; Said clutch shaft matched in clearance is in the axis hole of clutch cover; Have centrosymmetric two square grooves on the axis hole of said clutch cover; The width of said square groove is less than the width of said keyway, and a cell wall of a cell wall of said square groove and said keyway is on the same plane.
Have groove on the lower surface of said two clutch key, the two ends of said spring are inlaid in respectively in the groove of said two clutch key.
The bottom land of said groove has radial direction through hole.
Technique effect of the present invention is: compact conformation of the present invention, and safe and reliable, avoided the shared excessive defective in existing arrangement of clutch locus, easy to operate.When motor damages or have a power failure, can separate motor through manual handle, promote the combined floodgate or the separating brake of circuit breaker or switch; Good or when incoming call at electrical machmary maintenance, again can be through the combined floodgate or the separating brake of driven by motor switch or circuit breaker.

Embodiment
Be further described below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1～shown in Figure 5, the present invention is a kind of directed circumference formula arrangement of clutch, comprises clutch shaft 9.Have the axial keyway 6 that radially connects on the clutch shaft 9; Keyway 6 internal clearances are combined with two clutch key 3; The upper surface 8 of clutch key 3 is the inclined-plane, and the inclined-plane of two clutch key 3 laterally arranges, and is provided with spring 5 between two clutch key 3; Clutch key 3 can move up and down in the keyway 6 of clutch shaft 9 under the effect of spring 5.During spring 5 compression, the radially maximum height of two clutch key 3 and less than the height of keyway 6.Clutch shaft 9 matched in clearance have centrosymmetric two square grooves 2 on the axis hole of clutch cover 1 in the axis hole of clutch cover 1, the width of square groove 2 is less than the width of keyway 6, and a cell wall of square groove 2 and a cell wall of keyway 6 are on the same plane.This plane is the working face of clutch key 3 and clutch cover 1 square groove 2.When clutch shaft 9 or clutch cover 1 rotation, make the inclined-plane of clutch key 3 stressed, to lower compression spring 5.
Have groove 4 on the lower surface of two clutch key 3, the two ends of spring 5 are inlaid in respectively in the groove 4 of two clutch key 3.Design like this, spring 5 installing and locating are accurately convenient.
The bottom land of clutch key 3 grooves 4 has radial direction through hole 7, is used for ventilation, with the air pressure balance inside and outside the maintenance clutch key 3.
Fig. 1～shown in Figure 3 for first embodiment of the present invention, is input as clutch cover 1, is output as clutch shaft 9.Wherein clutch cover 1 is a driving link, links to each other with the axle of motor; Clutch shaft 9 links to each other with manual handle, is set to one.When driven by motor clutch cover 1 rotated, as shown in Figure 1, the working face rotation that the working face of clutch cover 1 drives clutch key 3 realized that clutch shaft 9 and clutch cover 1 are concentricity, equidirectional rotation, the combined floodgate of realization circuit breaker or switch; When motor damaged or have a power failure, clutch cover 1 stops the rotation, and was as shown in Figure 2, and drive clutch shaft 9 through manual handle and rotate separately this moment, and clutch shaft 9 separates with clutch cover 1, promptly separated with motor, realized the separating brake of circuit breaker or switch.
Fig. 4, shown in Figure 5 for second embodiment of the present invention, is input as clutch shaft 9, is output as clutch cover 1.Wherein clutch shaft 9 is a driving link, links to each other with the axle of motor; Clutch cover 1 links to each other with manual handle, is set to one.When driven by motor clutch shaft 9 rotated, as shown in Figure 4, the working face rotation that the working face of clutch key 3 drives clutch cover 1 realized that clutch cover 1 and clutch shaft 9 are concentricity, equidirectional rotation, the combined floodgate of realization circuit breaker or switch; When motor damaged or have a power failure, clutch shaft 9 stops the rotation, and was as shown in Figure 5, and drive clutch cover 1 through manual handle and rotate separately this moment, and clutch cover 1 separates with clutch shaft 9, promptly separated with motor, realized the separating brake of circuit breaker or switch.
Compact conformation of the present invention, safe and reliable, avoided the shared excessive defective in existing arrangement of clutch locus, easy to operate.When motor damages or have a power failure, can separate motor through manual handle, promote the combined floodgate or the separating brake of circuit breaker or switch; Good or when incoming call at electrical machmary maintenance, again can be through the combined floodgate or the separating brake of driven by motor switch or circuit breaker.
