Abstract
The Nd-Fe-B permanent magnetic stator that the utility model discloses a kind of in revolute joint; including for protecting the shell of permanent-magnet stator; permanent-magnet stator is housed on the outer casing inner wall; rotor is equipped in the shell; the permanent-magnet stator is covered in the outer ring of rotor; the upper and lower ends of the shell are designed with the fixed plate for fixing shell, are connected between the rotor and fixed plate by bearing.It is substantially the problem for using fixed stator to cause armature spindle service life shorter that the utility model, which overcomes and is traditionally used for motor in mechanical arm and revolute joint,.The utility model has many advantages, such as that structure is simple, easy for installation and long service life.
Description
Technical field
The utility model relates to a kind of permanent-magnet stators, more specifically to a kind of in revolute joint
Nd-Fe-B permanent magnetic stator.
Background technique
Original motor on mechanical arm and revolute joint substantially uses fixed stator, rotor rotation band motivation
Tool arm or joint of robot rotation, so all torque and torque can all concentrate on armature spindle, can shorten armature spindle use
Service life.Joint outer diameter can be larger simultaneously.
Utility model content
In order to overcome the above problem, now providing, there is the utility model one kind of long service life to be used for revolute
Nd-Fe-B permanent magnetic stator on joint.
A kind of Nd-Fe-B permanent magnetic stator in revolute joint of the utility model, including for protecting permanent magnetism
The shell of stator is equipped with permanent-magnet stator on the outer casing inner wall, is equipped with rotor, the permanent-magnet stator set in the shell
In the outer ring of rotor, the upper and lower ends of the shell are designed with the fixed plate for fixing shell, the rotor and fixation
It is connected between plate by bearing.This technology uses fixed rotor, directly uses permanent-magnet stator to rotate as extrinsic articulation component, that is, divides
Rotating torque and torque have been carried on a shoulder pole, has also reduced the size in joint simultaneously.
Preferably, the shell is in a rectangular parallelepiped shape, the outer casing inner wall is equipped with the one of cross section semicircular in shape
Number locating slot, the quantity of the No.1 locating slot is at least 5.The outer surface of the permanent-magnet stator is equipped with fixed with No.1
Position slot matches and No. two locating slots of cross section semicircular in shape, and the quantity of No. two locating slots is at least 5, described
The locating slot of No.1 locating slot and No. two locating slot composition circular in cross-section.It, can using No.1 locating slot and No. two locating slots
Rapidly and accurately permanent-magnet stator to be installed on outer casing inner wall.This technology use fixed rotor, directly use permanent-magnet stator as
The rotation of extrinsic articulation component, that is, shared rotating torque and torque, also reduces the size in joint simultaneously.
Preferably, the contact surface of the fixed plate and shell is equipped with for absorbing the pressure between fixed plate and shell
The cushion of power.The pressure between fixed plate and shell can be effectively absorbed using cushion, to extend fixed plate and outer
The service life of shell.
The utility model has the following beneficial effects: structure is simple, easy for installation, long service life.

No.1 locating slot 6 and No. two locating slots 7 form the locating slot 8 of circular in cross-section.
Be equipped with rotor 3 in the shell 2,1 set of the permanent-magnet stator outer ring in rotor 3, the shell 2 it is upper
Lower both ends are designed with the fixed plate 4 for fixing shell 2, are connected between the rotor 3 and fixed plate 4 by bearing 5, institute
The contact surface of the fixed plate 4 stated and shell 2 is equipped with the cushion 9 for absorbing the pressure between fixed plate 4 and shell 2.
Usage mode: a kind of Nd-Fe-B permanent magnetic stator being used in revolute joint of the utility model is installed to
Required operating position.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, in the field of the utility model, made changes or modifications all cover practical new at this any those skilled in the art
Among the scope of the patents of type.
