Rear end cap proposed by the present invention includes the motor of brake, includes rotating shaft, bearing, brake and rear end cap, axle
Take up and fit in rotating shaft.It is characterized in that：The rear end cap is divided into bearing chamber and brake chamber, is opened between bearing chamber and brake chamber
There is in shaft hole, shaft hole border be provided with a closure gasket groove, closure gasket groove and set sealing ring.Rotating shaft rearward end passes through shaft hole
The brake chamber of rear end cap is inserted, sealing ring will be sealed between rotating shaft and shaft hole.The bearing is placed in the bearing chamber of rear end cap
In, the compression assembling flexible member between bearing and shaft hole.The brake is placed in rear end cap brake chamber and is arranged on
Rotating shaft rearward end.
The brake includes brake rotor and brake stator, and brake rotor is arranged on the rearward end of rotating shaft, system
Dynamic device stator is arranged on rear end cap brake chamber.The spline tooth of brake rotor is engaged with the spline tooth of brake stator.
The sealing ring can select rubber, synthetic resin, felt etc. as needed, can be oil sealing, be covered with dust, or non-
Contact seal form.
The rear end cap is provided with action pane in brake chamber side.
The present invention realizes back end cover for motor and includes formation sealing between brake, and brake and bearing chamber, reduces dust
Influence to motor body.Rear end cap reservation operations window, meets during motor use, motor rear end is carried out in real time simultaneously
Operation and the demand of adjustment.This compact conformation is simple and direct, and space accounting is small, alleviates motor weight, meets lightweight requirements, just
In maintenance.

Embodiment
With reference to the accompanying drawings and examples, the present invention is described in further detail.
Embodiment
A kind of rear end cap includes the motor of brake, and its rotating shaft rearward end structure is as shown in Figure 1.Rotating shaft 1 is carried out with bearing 2
Assembling, it is ensured that rotating shaft 1 carries out tight set with the inner ring of bearing 2 and assembled.Brake rotor 7 is assembled to the rear end of rotating shaft 1, such as Fig. 4 simultaneously
It is shown.
As shown in Figure 1, 2, 3,5 points of rear end cap is bearing chamber and brake chamber.It is provided with and turns between bearing chamber and brake chamber
Border is provided with a closure gasket groove, closure gasket groove and sets sealing ring 4 in axis hole, shaft hole.The rearward end of rotating shaft 1 is put through shaft hole
Enter the brake chamber of rear end cap, sealing ring 4 will be sealed between rotating shaft 1 and shaft hole.Rear end cap is in brake chamber side provided with operation
Window.
The bearing 2 is placed in the bearing chamber of rear end cap, the compression assembling flexible member 3 between bearing and shaft hole.Axle
Hold between the bearing chamber of 2 outer rings and rear end cap 5 is interference fits.The cycle surface of bearing 2 is propped up after flexible member 3 simultaneously, bearing 2
Continue to be axially moved, by the precommpression certain size of flexible member 3, it is ensured that flexible member 3 is with the synergy of rotating shaft 1, eliminating
The bearing clearance of bearing 2.
Sealing ring 4 can select rubber, synthetic resin, felt etc. as needed, and concrete form can be oil sealing, be covered with dust,
Can be non-contact seals form etc..
Brake stator 6 is arranged on rear end cap brake chamber, the spline tooth of brake rotor 7 and the flower of brake stator 6
Key teeth is uniformly engaged.So far, the construction package assembling of whole rear end cap is completed.
The work of the present invention and braking procedure：Work as electrical power, the friction plate of brake stator 6 is in releasing orientation, braking
Device rotor 7 rotates under the drive of rotating shaft 1.Work as power-off, the locking friction plate of brake stator 6, after brake is fixed on
On end cap 5, remain static, brake rotor 7 is braked by the effect of spline tooth, countershaft 1, in this process
Friction plate can produce dust.Now, sealing ring 4 plays sealing function, prevents dust from entering in motor body.Motor was being operated
It is possible that exception, by the action pane of rear end cap 5, easily and efficiently can be adjusted or the later stage to motor in journey
Maintenance, example：Rotating shaft（Part 1）Inscribed screw mandrel, screw mandrel has extreme limit of travel point, when motor braking is in stroke limit, is again started up
, it is necessary to pass through rear end cap during motor（Part 5）Action pane be operated manually, screw mandrel is exceeded the maximum a little, so as to normally open
It is dynamic.
Whole process, it is easy for installation, it is simple to operate.This scheme is applied to include brake, and brake and rear bearing chamber
Between form sealing, reduce influence of the dust to motor body.Rear end cap reservation operations window, meets motor and uses process simultaneously
In, the demand for being operated and being adjusted to motor rear end in real time.This compact conformation, manufacture is easy, and space accounting is small, alleviates electricity
Machine weight, is easy to safeguard.
Motor disclosed in this invention, the features such as compact conformation, simple installation have been reached as far as possible.
