Brake manufacturing process：The basic ontology of brake is manufactured first, and winding 11, which is wound on by tooling on skeleton 12, to be passed through
Interference fit makes winding and skeleton be fixed in stator slot.Inject epoxy resin in stator slot, epoxy resin act as around
Group carries out insulation processing.It is subsequently placed into spring, a spring is uniformly placed in the stator, is sequentially placed into armature, armature is provided with slide opening
Coordinate with column sleeve 70, the surface of armature and limiting plate is handled by reticulate pattern to increase and friction disc brake power.By locking column sleeve
It is 0.15mm-0.2mm to make the gap width of armature and stator department when brake dead electricity.After friction plate is connected to stator department by gluing
In end recesses.
Finally installation increases positioning accuracy and improves torque portions device, and the partial devices are mainly by first wheel, friction
Disk, shrapnel, permanent magnet are constituted, and rear frictional disk is antifriction metal (AFM), and groove part is bonded annular permanent magnet, magnetic circuit direction
It is opposite with stator department bottom magnetic circuit direction.It is subsequently placed into shrapnel, shrapnel, which is forced through frictional disk, by screw locks the first round
In hub, ensure that frictional disk and first wheel gap width are 0.1mm.
Brake overall installation process：The material of first wheel is un-conducted magnetic material.The devices such as stator department are passed through into long spiral shell
Nail is locked on motor rear cover, is then pressed into wheel hub in motor shaft, and by keyway and holding screw by first wheel positioning device
It is locked, by pressure tooling by motor shaft from the stator part device rear portion fixed enter into.Until the first friction plate and the first round
Hub is worked good, and the first friction plate of the first end of frictional disk and stator department tightly posts, until frictional disk and first wheel gap
Value becomes 0 from 0.1mm, fixes motor shaft.Thus the brake gear installs.
Specifically, when brake guaranties, armature is attracted by stator department leading portion suction surface, and spring is compressed, and first rubs
Pad can institute's axis be freely rotated, stator department rear portion generate magnetic field repel each other with permanent magnet, repulsion act on frictional disk compress shrapnel,
First wheel has certain interval with stator department, free to rotate.Brake guaranties are not braking at this time.When brake is powered off due to
There is no the electromagnetic force that stator department generates, armature to be squeezed two sides and the limiting plate armature friction of the first friction plate by the spring force of spring
Generation frictional force is brake force, and since the first end of dead electricity stator department also loses magnetic field simultaneously, shrapnel generates elastic force to stator department
It squeezes, while the metal phase of permanent magnet and stator department attracts this process of quickening, when the first friction plate phase of frictional disk and stator department
When contact, it is brake also to generate brake at this time, and axis stops operating.
Rear and front end brake assemblies provide large torque for brake, so that brake is become safer, in this configuration
Rear end is due to having shrapnel and permanent magnet to act on so that brake is more fast, and tightly embraces motor shaft under large torque brake force
Extremely, this is braked for high-precision.High progress and large torque braking are realized with same winding, reaches effective energy-efficient effect.System
Dynamic device rear end high-precision positioner can be realized by elastic devices such as spring or shrapnels.Brake armature reticulate pattern or can be through
It gets processing ready and the techniques such as armature surface roughness can be improved.Coil rack is interference fitted with stator or passes through epoxy resin
Embedding is handled, or is fixed in stator slot by other techniques.The material of brake stator and armature is soft magnetic materials electrician
Pure iron, specifically, the stator and armature can be good by using soft magnetic materials punching or silicon steel sheet etc. and No. 10 steel magnetic properties
Material be made.
