Specific embodiment
A kind of specific embodiment of torque motor structure of the invention is described in detail below in conjunction with the accompanying drawings, the enforcement
Example is only illustrative of the invention and is not intended to limit the scope of the invention, various of equal value shape of the those skilled in the art to the present invention
The modification of formula falls within the application claims limited range.
Such as Fig. 1, a kind of torque motor structure, including aluminum shell body 1 install bearing chamber, bearing on the front end face of shell body 1
Room includes bearing block 2, bearing inner end cap 3, interior felt seal ring 4, bearing outer end cap 5 and outer felt seal ring 6, groups of corner connection
Tactile ball bearing 7 is installed on back-to-back in bearing room, has adjusted Internal and external cycle face size when in groups angular contact ball bearing 7 dispatches from the factory
Difference, the Internal and external cycle of two bearings need to be only adjacent to when using can reach suitable pretightning force and clearance, this group of bearing inner race connection
Motor shaft 8 is simultaneously fixed by round nut, and outer ring is fixed by bearing inner end cap 3 and bearing outer end cap 5, is installed groups of
Angular contact ball bearing 7 ensure that the axiality and axially position precision of motor shaft 8 and shell body 1, reduce the He of motor stator 9
The assembly difficulty of rotor assembly, can effective limiting motor axle 8 axial float；Motor stator 9 is mounted in shell body 1, by spiral shell
Nail compresses the end-face friction of the generation of stator end cap 10 makes it be fixed on shell body 1, and rotor assembly is arranged on electricity by screw
On arbor 8, rotor assembly includes that rotor 11, rotor fixed cover 12 and rotor fix end cap 13, and rotor 11 is mounted in and turns
On sub- fixed cover 12, the end-face friction realization fixation that end cap 13 is produced is fixed by screw in compression rotor；Aluminum bearing spider
14 be arranged on shell body 1 rear end face on, the endoporus of bearing spider 14 built with deep groove ball bearing 16, on the endoporus of bearing spider 18
Cannelure is provided with, groove can prevent bearing built with rubber ring 15, the inner ring sleeve of rubber ring 15 on the outer ring of deep groove ball bearing 16
Act as a travelling agent circle, the annular groove depth on the endoporus of bearing spider 18 is 0.8 times of the thickness of rubber ring 15, and width is the width of rubber ring 15
1.4 again；The outer ring of taper sheath 17 coordinates with the inner ring of deep groove ball bearing 16, and the rear portion of taper sheath 17 is equipped with round nut, by circle spiral shell
Female thrust is fixed on taper sheath 17 on the taper shaft part of motor shaft 8, while being realized by the tensioner deformation of taper sheath 17 deep
The inner ring interference of ditch ball bearing 16 is fixed, and be this configuration reduces and is required brought assembly difficulty because bearing internal external face coordinates.
Encoder 18 is fixed on the outer face of bearing spider 14, and its rotary shaft is fixed on motor shaft 8 by clasping structure
