Abstract
The invention discloses a zero-setting mechanism at the spline end of a motor shaft for a rotary transformer. The zero-setting mechanism is characterized in that a worm gear-worm transmission mechanism composed of a worm gear and a worm is arranged, the worm is used as a drive piece, the worm gear is used as a driven piece, a rotary shaft of the worm gear is used as an output piece, a spline sleeve is fixedly arranged at the shaft end of the rotary shaft, and the spline sleeve can be fixedly sleeved on the motor rotary shaft. According to the invention, fine adjustment for the motor rotary shaft and reverse self-locking can be realized by the arrangement of the large-transmission-ratio mechanism worm gear-worm mechanism; and the adjustment process is accurate and efficient.
Description
Technical field
The motor shaft splined end that the present invention relates to be applied in the permanent magnet driving motor for vehicle is revolved zero mechanism that modifies tone.
Background technology
Magneto is as the power output of new-energy automobile, and the quality of its performance directly has influence on dynamic property, comfortableness, the economy of car load.Because the permanent magnet drive motor of new-energy automobile has characteristics such as operational environment complicacy, volume is little, reliability is high, power density is big; Draw through comparison and analysis; Magneto has advantages such as high torque density, high power density, high efficiency, high reliability, therefore is widely used in the new-energy automobile.
Along with resolver replaces the application of Hall element on motor gradually; It mainly all is manual work that the adjustment of resolver is made zero; The feel that relies on the operative employee is with hammer and corresponding instrument, the piecemeal stator that strikes resolver; Its process wastes time and energy, and the adjustment precision is difficult to guarantee.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, provide a kind of motor shaft splined end to revolve modifying tone zero mechanism, to accomplish the trace adjustment of motor resolver fast and accurately.
The present invention has adopted following technical scheme for the technical solution problem:
The design feature that motor shaft splined end of the present invention is revolved zero mechanism that modifies tone is: the Worm and worm-wheel gearing that is made up of worm gear and worm screw is set; With worm screw as driving link; Worm gear is a Passive part; Rotation axis with worm gear is an output, fixedly installs a spline housing at the axle head of said rotation axis, and said spline housing can be solidly set on the machine shaft splined end.
Compared with present technology, beneficial effect of the present invention is embodied in: the present invention can realize the fine setting of machine shaft through the big speed ratio mechanism of worm and gear is set, and realizes reverse self-locking, makes adjustment process accurately, efficiently.

Embodiment
Referring to Fig. 1; The motor shaft splined end is revolved zero mechanism that modifies tone one Worm and worm-wheel gearing that is made up of worm gear 6 and worm screw 7 is set in the present embodiment; As driving link, worm gear 6 is a Passive part with worm screw 7, is output with the rotation axis 5 of worm gear 6; Axle head at rotation axis 5 fixedly installs a spline housing 9, and spline housing 9 can be solidly set on the machine shaft splined end.
Shown in Figure 1, in the practical implementation, worm screw 7 passes through Bearing Installation on endless screw support 8; Endless screw support 8 and base plate 1 are connected through bolt; Worm screw 7 and worm gear 6 engagements, worm gear 6 is installed on the rotation axis 5, and rotation axis 5 is installed on sleeve 2 and the socket cover 3 through bearing 4; Sleeve 2 is connected through the seam bolt with base plate 1, and rotation axis 5 is connected through flat key 10 with spline housing 9.
Fig. 2 a and Fig. 2 b illustrate matching used gripping apparatus version in the present embodiment; One end of gripping apparatus 11 is set to a cylindrical shell 11a; The claw 11b that protrudes out is arranged on the front end face of cylindrical shell 11a, and claw 11b can fix at the periphery concave surface place of the afterbody rotating disk 12 of resolver rotor (Fig. 3 and shown in Figure 4); The other end of gripping apparatus 11 is bolt hole 11c, and the screwed hole on bolt hole 11c and the electric motor end cap is on the relevant position, gripping apparatus 11 is fixedly installed on the electric motor end cap through the screwed hole on bolt hole 11c and the electric motor end cap by set bolt.When claw 11b is fixed the periphery concave surface place at the afterbody rotating disk 12 of resolver rotor; Gripping apparatus 11 is fixedly installed on the electric motor end cap through the screwed hole on bolt hole 11c and the electric motor end cap by set bolt, can stops the servo-actuated of resolver rotor and machine shaft.
In the adjustment process; The at first fixing stator of resolver; Remove the rotor of resolver and the annexation between the machine shaft, again by rotor and the electric motor end cap relative fixed of gripping apparatus 11, with the rotor of prevention resolver and the servo-actuated of machine shaft with resolver; Then, spline housing 9 is solidly set on the splined end of machine shaft, drives the rotation of worm screw 7 through external force; Promptly driving worm gear 6 simultaneously rotates; And through rotation axis 5 and spline housing 9 drive motors rotating shafts rotation, the relative position of machine shaft and resolver rotor is able to adjustment, when adjustment reaches accurate position; Remove gripping apparatus fixing to the resolver rotor, and resolver rotor and machine shaft be fixed on the accurate position of adjustment acquisition.
