Abstract

The utility model discloses a rotary zero-setting mechanism at a spline end of a motor shaft. The rotary zero-setting mechanism at the spline end of the motor shaft is characterized by comprising a worm gear and worm transmission mechanism consisting of a worm gear and a worm, wherein the worm serves as a driving component; the worm gear serves as a driven component; a rotating shaft of the worm gear serves as an output component; a spline sleeve is fixedly arranged at a shaft end of the rotating shaft; and the spline sleeve can be fixedly sleeved on a rotating shaft of a motor. Through arrangement of a worm gear and worm mechanism with a large transmission ratio, fine adjustment of the rotating shaft of the motor can be achieved and reverse self locking can be achieved, so that the adjusting process is accurate and efficient.

Description

The motor shaft splined end is revolved zero mechanism that modifies tone

Technical field

The utility model relates to the motor shaft splined end that is applied in the permanent magnet driving motor for vehicle and revolves 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 the characteristics such as operational environment complexity, volume is little, reliability is high, power density is large, draw through comparison and analysis, magneto has the 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, with hammer and corresponding instrument, the piecemeal stator that strikes resolver, its process wastes time and energy, and adjusts precision and is difficult to guarantee.

Summary of the invention

The utility model is for avoiding the existing weak point of above-mentioned prior art, provide a kind of motor shaft splined end to revolve modifying tone zero mechanism, to finish fast and accurately the trace adjustment of motor resolver.

The utility model is that the technical solution problem has adopted following technical scheme:

The design feature that the utility model motor shaft splined end is revolved zero mechanism that modifies tone is: a Worm and worm-wheel gearing that is made of worm gear and worm screw is set, with worm screw as driving link, worm gear is Passive part, take the rotation axis of worm gear as output, axle head at described rotation axis is fixedly installed a spline housing, and described spline housing can be solidly set on the machine shaft splined end.

Compared with the prior art, the utility model beneficial effect is embodied in: the utility model can be realized the fine setting of machine shaft by 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 of worm gear 6 and worm screw 7 is set in the present embodiment, with worm screw 7 as driving link, worm gear 6 is Passive part, take the rotation axis 5 of worm gear 6 as output, axle head at rotation axis 5 is fixedly installed a spline housing 9, and spline housing 9 can be solidly set on the machine shaft splined end.

Shown in Figure 1, in the implementation, worm screw 7 is installed on the endless screw support 8 by bearing, endless screw support 8 and base plate 1 are connected by 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 by bearing 4, sleeve 2 is connected by the seam bolt with base plate 1, and rotation axis 5 is connected by 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, front end face at cylindrical shell 11a has the claw 11b that protrudes out, 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 by the screwed hole on bolt hole 11c and the electric motor end cap by set bolt.When the periphery concave surface place that claw 11b is fixed at the afterbody rotating disk 12 of resolver rotor, gripping apparatus 11 is fixedly installed on the electric motor end cap by 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, by gripping apparatus 11 that the rotor of resolver is relative with electric motor end cap fixing again, servo-actuated with the rotor of prevention resolver and machine shaft; Then, spline housing 9 is solidly set on the splined end of machine shaft, drive the rotation of worm screw 7 by external force, namely driving simultaneously worm gear 6 rotates, and by rotation axis 5 and spline housing 9 drive motors rotating shafts rotation, the relative position of machine shaft and resolver rotor is adjusted, when adjustment reaches accurate location, remove fixing to the resolver rotor of gripping apparatus, and resolver rotor and machine shaft be fixed on the accurate location of adjusting acquisition.
