Abstract
The utility model relates to a friction clutch, particularly a clutch which uses an electromagnet to drive centrifugation blocks to control the starting. The utility model comprises a main shaft, a band wheel outside the main shaft, control units, an electricity guiding component, and a clutch component installed on the main shaft by a bearing. In the clutch component, an inner chamber of a fan-shaped box ring is provided with a brake block which moves along the radial direction of the inner chamber. The outer end of the brake block can be contacted with the inner wall of the band wheel. The inner wall of the box ring is installed on the bearing, and the side surface of the box ring is provided with a recess or a bulge which can be matched with the active arresting devices in the control units.
Description
The utility model relate to friction clutch, specifically a kind of utilize electromagnet drive centrifugal control from the clutch that closes.
Existing friction clutcch can be divided into manual, pneumatic and centrifugal three kinds according to its mode of operation.Wherein manual clutch can't be controlled automatically by the manpower manual operations; Pneumatic clutch is power with pressurized air, needs supporting air compressor and gas circuit annex, increases material consumption and energy consumption, and centrifugal clutch only is used for motor start-up, then can not separate after the startup, thereby be not really real clutch.
The purpose of this utility model be design a kind of utilize electromagnet and centrifugal control from the clutch that closes, to overcome above-mentioned defective.
Its main technical schemes comprises main shaft and main shaft outer belt wheel and controlling component, draws electric parts and utilizes the clutch part of Bearing Installation on main shaft, in clutch part, the inner chamber of fan-shaped box ring is placed can be at the radially mobile brake shoe of this inner chamber, the outer end of brake shoe can contact with the inwall of belt wheel, the inwall of box ring is installed on the bearing, and the groove or the projection that can match with the movable pallet in the controlling component are arranged in the side of box ring; Yoke is installed in the sleeve that is anchored on the main shaft in controlling component, coil is arranged in the yoke, axially movable armature is arranged in the coil, armature utilizes non magnetic link and pallet affixed, coil has two groups, wherein one group can produce after energising and make armature toward the magnetic force that moves right, and another group can produce the magnetic force that armature is moved to the left after energising; Coil also can only be used one group, at this moment should connect to make armature and the axially movable Returnning spring of pallet on armature or pallet; Outer rim at brake shoe is installed brake shoe; Spacing bearing pin is arranged on the box ring, and the borehole jack on the brake shoe is on this bearing pin, and this hole and between centers are gapped; In drawing electric parts, rotary slip ring is fastened on the end of sleeve, and this slip ring can dynamically contact with the elasticity fixed contact on being connected wire board, to realize dynamic power.
The utility model has the advantages that because the fan-shaped box ring that outside main shaft, utilized Bearing Installation, and the brake shoe brake shoe that placement can move radially in the box ring, when the pallet that rotates with main shaft stretches into projection or groove on the box ring, after driving box ring, brake shoe rotation, because of action of centrifugal force, brake shoe can tightly be posted on the inwall of belt pulley, utilizes the effect of frictional force, the drive belt pulley rotates, and it is simple in structure, reliable; Secondly, utilize the magnetic force of electromagnet to drive pallet and stretch into projection or groove on the clutch ring, with solenoidoperated cluthes from close, operate more convenient, but only need press just controlled clutch action of button, and,, in electromagnetic force pallet is driven so and can allow coil blackout after putting in place if adopt two coils that can produce different magnetic force direction.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is A-A view of Fig. 1.
As shown in the figure: outside main shaft (1), utilize flat key to connect sleeve (2), outside sleeve, utilize bearing to connect fan-shaped box ring (4), in the box ring, put the brake shoe (7) and bearing shell (6) that can move radially in the centrifugal action lower edge, spacing bearing pin (8) also is installed in fan-shaped box ring, this bearing pin passes the hole on the brake shoe (7), and between this hole and bearing pin, leave gap (16), so that brake shoe can move radially, can unconfinedly not move again, brake shoe is the part that fuses with belt wheel (5) outward, and there is projection box ring side.
The other end inner chamber of sleeve (2) is equipped with yoke (10) and coil (9), be can axially movable armature (11) in the coil, this armature utilizes non magnetic link (15) to fixedly connected with pallet (3), the coil of right-hand member gets when electric in the coil (9), the electromagnetic force that is produced will drive armature and pallet moves right, pallet is stretched in the projection of box ring side, driving the box ring rotates with main shaft, because action of centrifugal force, brake shoe in the box ring, brake shoe outwards moves, tightly be posted on the belt wheel inwall, frictionally drives belt wheel and rotates, when needs separate, connect the left end coil, the magnetic force left that it produced just can make armature and pallet be moved to the left, and makes pallet leave projection, and box ring and belt wheel stop operating voluntarily because of no driving force.Utilizing Bearing Installation belt wheel (5) near the sleeve (2) of coil-end is outer, be connected with rotary slip ring (12) at the end face of this end of sleeve, this slip ring can move with the elasticity fixed contact (13) on being connected wire board (14) and contact, so that external power is introduced coil.
Claims (7)
