Friction clutch
专利摘要:
<P> Coupling for transmitting torque. The transmission intended to communicate to one of the two aligned parts of this coupling the rotary movement of the other is a sleeve that supports balls interposed between axial grooves of the driving part and the driven part, both in the forward direction only in reverse. An elastic mechanism allows uncoupling in both directions of rotation if the torque exerted exceeds a certain value. Application especially to tapping pins. </ P> 公开号:SU725573A1 申请号:SU2319701 申请日:1976-02-05 公开日:1980-03-30 发明作者:Стен Джонсон Аллан 申请人:Тепматик Корпорейшн (Фирма); IPC主号:
专利说明:
for the reverse rotation device, and the main row of the ball is fixed - along the axis relative to the internal rotating element. The clutch is equipped with a torque limit mechanism. The separator is mounted on an internal rotating element. The separator is spring loaded but the axis on both sides. ha fig. Figure 1 shows a threading device using a clutch; in fig. 2 — clutch in cross-section; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 - separator; in fig. 6 shows a sectional coupling clutch; in fig. 7 is a section bb of FIG. 6; in fig. 8 - part of the spindle. The clutch is mounted on a metal cutting machine 1 having a mandrel 2, a thread cutting device 3 and a radial holding lever 4, which contacts a pillar 5 that holds the device 3 against rotation. The clamping cartridge 6 is fixed on the spindle 7 and has a tap 8 fixed by a nut 9. The cylindrical body 10 includes a sleeve And having an external thread and a tapered bore 12 in which the end of the mandrel 2 is located. A threaded ring 13 is screwed onto the thread. The lever 4 is attached to the body 10 with screws 14. The ball bearings 15 rotate the sleeve 11 in the body 10. The sleeve 11 has holes 16 arranged parallel to the axis, in which the springs 17 are located abutting against the support plate 18. The threaded washer 19 has a cup 20. The washer 19 is screwed onto the sleeve I. The separator 21 has balls 22 placed between the support plate 18 and the washer 19. The springs 17 are mounted on the balls 23, which are inserted into the slots 24 of the friction disk 25. The rotational moment is controlled by the washer 19 through the hole 26, closed by the turn ring 27, with a tool inserted into the hole 28. The outer rotating member 29 has an opening 30, a cup 31, which actuates a reversing mechanism, and a flange 32 on which a disk 25 is mounted. The ball bearing 33 provides the element 29 rotation. The spindle 7 is connected to the inner turn, element 34, which has a hole 35. A hole of greater diameter 36 is placed in the hole 35, which has a flange 37 and a recess 38. The rod 39 rotates through the holes 40 in the sleeve 11 of the hole 41 in the part 36. A screw prune 42 is located around stem 39 hell detail 36. The element 34 has an axial hole 43. The rod 39 passes into this hole. In the hole around the stem 39, under the part 36, there is a coil spring 44 which is held by a screw head 45 and a washer 46. The element 29 has longitudinal grooves 47 in which the balls 48 are held, held by the separator 49. The separator 49 is a sleeve. cylindrical, spring loaded springs 50 and 51. Longitudinal grooves 47 have a cross section in the form of balls 48. Internal rotating member 34 also has longitudinal grooves 52 in the form of balls 48. The sleeve 53 of the reversing mechanism has similar longitudinal grooves 54 and a ring gear 55. A flange 56 is fixed to the housing 10. The ring gear 55 is driven by a planetary gear mechanism. The driven spindle 7 rotates in a sliding bearing 57 mounted in flange 56. Reversible gears 58 are mounted on axles 59, the lower end of which is mounted in the holes 60 of the flange 56. The bearing 61 is made of a suitable material, for example bronze. The gears engage with the outer gear 62. The gasket 63 is located on the flange 56, which is fixed axially with the ring 64. The sleeve 53 of the reversing drive has longitudinal grooves 54, similar to the grooves 47, they engage the balls 48 for a reversing drive. The tap holder or clamping cartridge 6 is cylindrical with a hole 65 and has dies 66, driven by a threaded rod 67. The lower end 68 of the hole 65 has a tapered portion into which an expandable splitter collet 69 for the tap 8 is inserted. The end of the spindle has A thread 70 for tightening the nut 9. Between the nut 9 and the collet chuck 69 is a shim 71, having a tapered bore. FIG. 6-8 show a modified form of the invention. The spindle 7 has longitudinal grooves 72. The upper separator 73 has a flange 74 and balls 75, partially located in the grooves 72. The separator 73 is preloaded by a spring 76, which acts on the flange 74 and abuts the other end on the annular shoulder 77. When the spindle 7 moves downwards, the spring 76 becomes cocked and the balls are released from the grooves 72. The lower separator 78 has an additional row of balls 79, is located inside the sleeve 53, which has longitudinal grooves 80, is pressed by a spring 81 supported on the shoulder 82 in the sleeve 83, inside which spindle rotated. The clutch works as follows. The machine moves the spindle 1 before threading begins. With the start of thread cutting, spindle 7 begins to move relative to the body 10. When the tool reaches the limit of movement, the balls 48 move downwards with the separator 49, while the spindle 7 also shifts down. Since the balls can roll when axially moved, the drive is almost frictionless. When the balls reach the ends of the longitudinal grooves 47, the clutch is turned off without friction and vibration. The clutch drive is disengaged without vibration or shock. Spring 50 is nodzhata or cocked during movement. When the balls 48 reach the ends of the longitudinal grooves 47, they are quickly mixed by the spring 50 to the uncoupling position. When moving the spindle 7 down the balls 48 are engaged with the grooves 54 of the reversing drive. Spring 51 facilitates the re-engagement of the balls 48 through the pairs 47 in direct transmission. If there is an excessive torque, the clutch is switched off both in direct gear and in reverse gear.
