Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As shown in Figure 1, the dual-purpose clutch of high-capacity direct-driving frequency conversion of the present embodiment, including the housing 2 being installed on power transmission shaft 1, cover plate 3, clutch shaft 4 and clutch component, gear-driven assembly 5 on clutch shaft 4 is positioned in housing 2, the axial wall of clutch shaft 4 is with the first external toothing, clutch shaft 4 is rotationally connected with power transmission shaft 1 by bearing 11, is provided with single-row bearing 111 between clutch shaft 4 and the power transmission shaft 1 of shown gear-driven assembly 5 side, and opposite side installs double-row bearing 112；Clutch component includes driving ring 6, fixed disk 7 and the floating disc 8 being sequentially arranged from outside to inside.
As it is shown on figure 3, drive the inwall interval of ring 6 with multiple arc draw runners 61, its outer wall, with inner spring seat 62, drives the side intervallum of ring 6 to have the limiting plate 63 that the heart extends wherein.
As shown in Figure 4, the inner ring of fixed disk 7 is with the first ring gear, and its outer wall is with multiple spaced apart guide pads 72, and with the inclined guide surface 73 coordinated with arc draw runner 61 on guide pad 72, the outer wall of fixed disk 7 is with outer spring seat 74；As shown in Figure 6, fixed disk 7 is placed in driving ring 6, and limiting plate 63 is placed between adjacent guide pad 72, installs the first spring 9 between inner spring seat 62 and outer spring seat 74；Also with the stopper slot 75 being positioned at inclined guide surface 73 upper end on guide pad 72.
As shown in Figure 5, floating disc 8 is with axial step structure, including path dish 81 and big footpath dish 82, the inner ring of path dish 81 is with the second ring gear 83 engaged with the first external toothing of clutch shaft 4, and the outer ring of big footpath dish 82 is with the second external toothing 84 engaged with the first ring gear of fixed disk 7；Second spring 10 is installed between floating disc 8 and clutch shaft 4.
Work process of the present invention is as follows:
During washing of drum type washing machine, traction apparatus (is not drawn in figure, belong to prior art) use fixing bar (not shown) to drive driving ring 6 to turn clockwise, drive under the guide effect of arc draw runner 61 of ring 6, promote floating disc to press for 8 times i.e. to promote to clutch shaft 4, second external toothing 84 of floating disc 8 engages with the first ring gear of fixed disk 7, and the second ring gear 83 of floating disc 8 engages with the first external toothing of clutch shaft 4, and clutch shaft 4 is in the lock state with cover plate 3；Power transmission shaft 1 carries out rotating under the driving of motor, makes washing machine be in washing state；
During laundry machine dehydration, traction apparatus uses fixing bar to drive driving ring 6 to rotate counterclockwise, floating disc 8 departs from fixed disk 7 under the rebound effect of the first spring 9 and the second spring 10, clutch shaft 4 and cover plate 3 unlock state, make it can rotate freely under the drive of power transmission shaft 1, reach the purpose of laundry machine dehydration.
In the present invention, bearing 11 is divided into inside and outside circle, centre to be connected by ball.Outer ring and clutch shaft 4 interference fit, inner ring and power transmission shaft 1 matched in clearance.Power transmission shaft 1 is when by radial force effect, and inner ring keeps relative static conditions with it, has rotated work by ball in bearing.Thus reducing the friction of power transmission shaft 1 and inner ring, bearing carries certain play simultaneously, can revise the axiality problem of bearing inner race and power transmission shaft 1 dynamically, is more conducive to assemble, can significantly extend life of product.
The present invention uses the engaging structure of gear to replace traditional brake band, and it has feature the most easy to wear, that the strength of materials is high, job stability is high, also improves torque resistant intensity, it is ensured that the normal work of washing machine.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees claim, and in the case of the spirit of the present invention, the present invention can make any type of amendment.
