Description
Technical field
The utility model belongs to the elevator car safety technical field, is specifically related to a kind of elevator traction machine and uses plate disc brake, is the improvement to existing plate disc brake structure
Background technology
GB7588-2003 " elevator manufacturing and installation safety standard " stipulates that all participations should divide two groups of devices to the drg mechanical part of brake wheel or brake disc brake activation power; If one group of parts is inoperative, should still have enough braking forces to make to be loaded with rated load to slow down descending with the descending car of command speed.And the patent of Chinese utility model Granted publication CN201068359Y discloses a kind of " gearless permanent-magnet synchronous traction machine "; The drg of this towing machine is made up of one group of brake disc and circular electromagnets; This device is behind the circular moving iron core et out of order of monoblock; Just can't realize braking, thereby the person and property safety are caused great loss towing machine.
are to the problems referred to above; Someone is divided into a plurality of single-decks with the circular moving iron core of monoblock and becomes how the group devices are braked towing machine; " a kind of braking method of towing machine and device thereof " disclosed like Chinese invention patent application publication number CN101850938A; But through a static iron core and more than two with static iron core over against the moving iron core of self contained function with the mode of one-to-many brake disc is carried out control of braking, this moving iron core more than two pieces together a full circle.The advantage that this structure has is: through using more than two independently moving iron core, satisfy when moving iron core et out of order wherein, other moving iron core still can obtain enough braking forces elevator traction machine is braked.But still there is following problem in this structure: at first, this drg is only installed a toroid winding; The close skewness of toroidal magnetic is so the distribution of electromagnetic force that produces is inhomogeneous, in the moment of energising; Each moving iron core discontinuity shows as the suffered power of inner headed face part usually greater than the suffered power of periphery part, when moving iron core passes through guide finger to the static iron core adhesive; Moving iron core can tilt because of unbalance stress generation bending; Make guide finger produce resistance, cause of the internal and external parts simultaneously adhesive of dynamic and static iron core, produce noise and unstable properties at two faces that face each other to moving iron core; Secondly; This drg has only adopted one group of brake disc and one group of moving core assembly; In the time of on being installed in the big elevator traction machine of lock torque requirement, if moving iron core et out of order wherein, though other moving iron core could be along with carrying out adhesive or release between energising or outage and the static iron core; But the friction force that produces between moving iron core of part and the brake disc possibly be not enough to the stop towing machine, has potential safety hazard equally.
For this reason, the applicant has carried out actively and the actv. trial, and the technical scheme that will introduce below produces under this background
