Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in further detail the embodiment of the present invention below in conjunction with the drawings and specific embodiments.
The invention provides a kind of clutch structure, as shown in Figure 1, comprising: back-moving spring 1, clutch shaft 2, fixed rotating shaft 3 and push rod 4.
The lower end surface of clutch shaft 2 has the groove 21 coordinated with motor output shaft 50, clutch shaft 2 is set on motor output shaft 50 by groove 21.Usually, motor output shaft 50 is square along the cross section perpendicular to its axis, corresponding, the shape of groove 21 on the end face of place is square.Clutch shaft 2 can move along its axis.
Back-moving spring 1 is set on motor output shaft 50, and the lower end surface of back-moving spring 1 is against the root of motor output shaft 50, and upper end end face is against the end face at groove 21 place of clutch shaft 2.Back-moving spring 1 can be supplied to the elastic force of clutch shaft 2 away from motor 5.
The lower end of fixed rotating shaft 3 and the upper end of clutch shaft 2 can engage each other, and upper end to be fixed on guidance panel 6 and can around the axial rotation of fixed rotating shaft 3.Operating personnel can by rotating the conversion operations that fixed rotating shaft 3 realizes dual-power transfer switch.
The lower end of push rod 4 is against on the upper end end face of clutch shaft 2, and upper end to be fixed on guidance panel 6 and can to move along the direction being parallel to fixed rotating shaft 3 axis.
When push rod 4 is pressed, clutch shaft 2 and fixed rotating shaft 3 depart from (see Fig. 2), and motor output shaft 50 dallies; When push rod 4 is upspring, clutch shaft 2 engages (see Fig. 1) with fixed rotating shaft 3, and the rotation of motor output shaft 50 is delivered on fixed rotating shaft 3.Operating personnel can be realized the disengaging of clutch shaft 2 and the control operation of again engaging with fixed rotating shaft 3 by push rod 4, thus carry out clutch operation to fixed rotating shaft 3 and motor 5 in whole clutch operation process.
Clutch shaft 2 and fixed rotating shaft 3 can coaxially also can non-coaxial.
When clutch shaft 2 and fixed rotating shaft 3 are coaxial, see Fig. 3, the upper end end face of described clutch shaft 2 has the key 22 of protrusion, described key 22 can in cuboid as shown in Figure 3.And the lower end surface of described fixed rotating shaft 3 has the keyway 32 (see Fig. 4) coordinated with described key 22.Now, push rod 4 is along the through fixed rotating shaft 3 of axis of fixed rotating shaft 3, and the lower end of push rod 4 offsets through the bottom surface of described keyway 32 and the end face of described key 22, and upper end is fixed on guidance panel 6 by the upper end of fixed rotating shaft.The lower end surface that push rod 4 contacts with clutch shaft 2 can be the shape such as ellipse, circle, polygon.When clutch shaft 2 and fixed rotating shaft 3 adopt the fit system of key and keyway, key on clutch shaft 2 perpendicular to clutch shaft 2 cross section axially can also be oval, semicircle, polygon or other shape, transmission can rotate when clutch shaft 2 is laminated with fixed rotating shaft 3.
When clutch shaft 2 and fixed rotating shaft 3 are coaxial, see Fig. 5, the lower end surface of described fixed rotating shaft 3 has the key 33 of protrusion, described key 33 can in cuboid as shown in Figure 5.And the upper end end face of described clutch shaft 2 has the keyway 23 (see Fig. 6) coordinated with described key 33.Now, described push rod 4 is along the through fixed rotating shaft 3 of axis of fixed rotating shaft 3, and the lower end of push rod 4 offsets through the end face of described key 33 and the bottom surface of described keyway 23, and upper end is fixed on guidance panel 6 by the upper end of fixed rotating shaft 3.The lower end surface that push rod 4 contacts with clutch shaft 2 can be the shape such as ellipse, circle, polygon.When clutch shaft 2 and fixed rotating shaft 3 adopt the fit system of key and keyway, key on fixed rotating shaft 3 perpendicular to fixed rotating shaft 3 cross section axially can also be oval, semicircle, polygon or other shape, transmission can rotate when clutch shaft 2 is laminated with fixed rotating shaft 3.
When clutch shaft 2 and fixed rotating shaft 3 non-coaxial, see Fig. 7, the lower end outside of described fixed rotating shaft 3 has the gear 34 around fixed rotating shaft 3, have around clutch shaft 2 outside the upper end of described clutch 2 and can with gear 34 pitch wheel 24 of fixed rotating shaft 3.Described push rod 4 is positioned at the outside of fixed rotating shaft 3, the shank portion of push rod 4 is through at least one fairlead 7, described fairlead 7 is fixed relative to guidance panel 6 position, fairlead 7 can be the cylindrical shell extended from guidance panel 6, and such as twin-power switch, fairlead 7 can be fixed in certain structure of twin-power switch.Thus, guidance panel 6 and fairlead 7 can limit the moving direction of push rod 4.The lower end surface that push rod 4 contacts with clutch shaft 2 can be the shape such as ellipse, circle, polygon.The axis of push rod 4 and fixed rotating shaft 3 can be parallel to each other, like this on guidance panel 6, push rod 4 and fixed rotating shaft 3 can be connected two independently operating key or control handles, the operating key of fixed rotating shaft 3 or control handle can drive fixed rotating shaft 3 around its axial-rotation, and the operating key of push rod 4 or control handle can drive push rod 4 axially press along it or upspring.
Described clutch structure preferably can also comprise limit shaft sleeve 8 (see Fig. 8), the lower end of described limit shaft sleeve 8 is fixed on motor 5, and surround motor output shaft 50, back-moving spring 1 and clutch shaft 2, the inwall of limit shaft sleeve 8 and the smooth laminating of outer wall of clutch shaft 2.Thus, clutch shaft 2 pushed by push rod 4 and by the elastic force effect of back-moving spring 1 along more stable during self move axially, can avoid rocking.
For the situation that clutch shaft 2 is coaxial with fixed rotating shaft 3, on the lower surface of fixed rotating shaft 3 (see Fig. 9) can be supported in the upper surface of limit shaft sleeve 8; Limit shaft sleeve 8 also can be set in the lower end (see Figure 10) of fixed rotating shaft 3 further, now, the inwall of limit shaft sleeve 8 is circular along the cross section perpendicular to its axis, the lower end edge of fixed rotating shaft 3 is also circular perpendicular to the cross section of its axis, like this, when motor 5 drives limit shaft sleeve 8 to rotate, fixed rotating shaft 3 can not be followed motor 5 and be rotated.
Clutch structure of the present invention is upper outside except being applied in twin-power switch, and can also be applied in other needs to carry out in the structure of clutch operation with motor.
Clutch structure of the present invention can with existing motor directly with the use of, do not need to change (existing motor and gear box normally Integral design) to motor and gear box, need not adjust the size of gear box yet, easy to use; The number of spare parts forming clutch structure is less, and therefore cost is also lower.
Clutch structure of the present invention, its clutch shaft can be set on motor output shaft and slide up and down, when clutch shaft is pressed by push rod, fixed rotating shaft and clutch shaft depart from, when push rod is upspring, clutch shaft engages with fixed rotating shaft, and the rotation of motor output shaft is delivered on fixed rotating shaft, thus realizes the clutch operation to fixed rotating shaft and motor.By arranging limit shaft sleeve outside motor output shaft, back-moving spring and clutch shaft, the slip of clutch shaft can be made more stable.
