Relatively.Left support tablet 8 and right support tablet 9 are support tablet, and left support plate 5 and right support plate 6 are support plate.
Among the top of installation foot along the axial direction of shaft and far from drive direction open up it is fluted, groove include it is upper
Groove 13 and lower groove, the middle part of upper groove 13 and lower groove are mutually communicated, and upper groove 13 penetrates through the both sides of installation foot, upper groove
13 form arc-shaped supporting surface 18 towards the side of the bottom end of installation foot, and the edge of rear cover 1 is extruded on supporting surface 18.Circular arc
The rear cover 1 of shape is extruded on supporting surface 18 so that rear cover 1 can be formed with upper groove 13 and completely be fitted closely, especially rear
In the case that the radius of lid 1 is identical with the radius of curvature of supporting surface 18, effectively limitation is so that installation foot turns along the circumferential direction of rear cover 1
It is dynamic.
Under lower groove includes the lower rectangular channel 14 to match with support writing board shape and matches with support plate shape
Triangular groove 15, lower rectangular channel 14 and lower triangular groove 15 are mutually communicated, and support tablet is fitted in axial direction of the lower rectangular channel 14 along shaft
Face on, support plate be fitted in lower triangular groove 15 along turn axial face along, lower triangular groove 15 is provided with along the axial direction of shaft
Screw hole 17 is equipped with screw in screw hole 17, and support plate is fixedly connected by screw with installation foot.It is flat that lower rectangular channel 14 accommodates support
Plate, the bottom end of lower triangular groove 15 be again provided with 7 corresponding structure of fillet, it is made to be matched with support plate shape, lower triangular groove
15 effectively accommodate support plate.In the case, the structure of width gradual change is integrally presented in lower groove, on the one hand installation foot is facilitated to be inserted in
Installation, but only due to lower triangular groove 15, support plate is easily circumferentially easily skidded off from lower triangular groove 15, but support tablet
It can ensure that integrally convenient stable installation is fixedly mounted on the basis of foot lower groove, eliminates above-mentioned movement tendency to greatest extent,
So that connection is the most firm.
The bottom end of installation foot is provided with circular fixing port 16, and fixing port 16 is set along the axial direction of shaft, installation foot
Bottom end is fillet 7.In order to stablize motor, the installation foot being used to support should need as far as possible with ground more than contact surface, still
Front left installation foot and front right installation foot are symmetrically installed, and rear left installation foot and rear right installation foot are symmetrically installed, by installation foot bottom end
Fillet 7, effectively so that motor can smoothly reply stable state again along left bank or along right bank, successfully manage electricity
The Vibration Condition during operation of machine, simultaneously because installation foot so that motor is far from ground, the occurrence of mode is made moist.
P plates shell includes P plates procapsid and P plate back casings.The bottom surface of P plate procapsids and the bottom surface of P plate back casings are equal
It is arc-shaped.The bottom surface of P plate back casings is stuck in chuck 10, and sealing structure is formed between P plates back casing and chuck 10.P plates
Back casing splices close to the one side of drive and the top of P plate procapsids, and the bottom of P plate procapsids leans against the upper surface of round platform 11
The bottom surface of 12, P plate procapsids is arc-shaped surface, and the bottom surface of P plate procapsids is connected with the edge of No. two turn holes, after P plates
Winding displacement groove is formed on the top of housing and P plate procapsids, and winding displacement is mounted in winding displacement groove, the bottom and round platform 11 of P plate procapsids it
Between form P board slots, P plates are installed in P board slots, and P plates are connected with winding displacement.On the one hand the structure efficiently uses space, reduce into
This, on the other hand, reduces the use of material, it is ensured that leakproofness reduces the danger of infiltration.
The bottom of P plate procapsids is provided with support ring, and support ring includes ring 20 after support front ring 19 and support, supports front ring
19 are coaxially disposed with ring 20 after support.Shaft is located on the axis of support ring, and ring 20 is integrally formed after support front ring 19 and support,
The diameter of front ring 19 is supported to be more than the diameter of ring 20 after support, the axis of ring 20 and round platform 11 along shaft after support front ring 19, support
To setting gradually, the bottom surfaces of P plate procapsids is stuck in after support on ring 20, and support front ring 19 is along the axial compression of shaft in P plates
Procapsid is in the one side of drive.Ring 20 supports P plate shells after support, while also acts the work of stable P plates shell position
With having filled up the gap between P plates shell and shaft, also reversely stabilized the position of shaft, it is made to influence each other.Support front ring 19
Also direction causes P plates shell on round platform 11, to play the role of limiting by firm compression so that P plate shell inner sealings are good.
Moreover, support front ring 19 also acts the effect for reducing axis friction with ring 20 after support.
Bearing includes inner bearing 21 and outer bearing 22, and multiple steel balls are provided between inner bearing 21 and outer bearing 22
23, outer bearing 22 is set to the outside of inner bearing 21, and all steel balls 23 are circumferentially distributed along inner bearing 21, and inner bearing 21 passes through
Steel ball 23 is connected with each other with outer bearing 22, and steel ball 23 is restricted to move between inner bearing 21 and outer bearing 22.In 21 sets of bearing
The outside of shaft is connected on, the outside of outer bearing 22 is socketed with protecgulum 24, and the shape of protecgulum 24 is cylinder, and the center of protecgulum 24 is
Hollow-core construction, bearing are set in hollow-core construction, the central shaft of protecgulum 24 and the center overlapping of axles of shaft, and protecgulum 24 is close to transmission
The bottom surface of wheel is front end face 25, and bottom surface of the protecgulum 24 far from drive is rear end face 26, and front end face 25 and rear end face 26 penetrate through
In hollow-core construction, front end face 25 is socketed on the end face of outer bearing 22, the exposed inner bearing 21 of front end face 25 and steel ball 23, protecgulum 24
Side fitting be stuck in the side of outer bearing 22, rear end face 26 exposes bearing, and rear end face 26 is circumferentially provided with multiple fixations along it
Plate 27, fixing insertion 27 are fixedly connected perpendicular to shaft, fixing insertion 27 with plastic packaging.Shaft is realized by inner bearing 21 to be reduced
The purpose of friction, and outer bearing 22 so that plastic packaging is connect with protecgulum 24, on the one hand protecgulum 24 stablizes outer bearing 22, turn so as to stablize
The rotation of axis, it is on the other hand easy to disassemble, its operation is not influenced, while shaft further with plastic packaging stable connection, is reduced
The unstability of operation.In rolling friction is changed by 23 pivoting friction of steel ball between bearing 21 and outer bearing 22,
On the basis of not influencing operation stability, friction is reduced to greatest extent.
