Abstract
The utility model discloses a zero adjusting device of a rotary transformer. The zero adjusting device of the rotary transformer comprises the rotary transformer and a zero adjusting member, an inner hole is arranged in the center of the zero adjusting member, and grasping grooves are arranged at the edges of the zero adjusting member. A stator of the rotary transformer is clamped in the inner hole of the zero adjusting member, and the zero adjusting member is rotated via the grasping grooves to drive the rotary transformer to rotate, so that the zero is found. The zero adjusting device of the rotary transformer of the utility model can adjust the zero of the rotary transformer rapidly during the motor running process, is simple, convenient, safe and reliable, and enables the time to be saved and the accuracy to be increased.
Description
Technical field
The utility model belongs to motor frock technical field, relates to a kind of resolver zero-bit adjusting device.
Background technology
Permagnetic synchronous motor is after installing resolver, and its zero-bit often needs to regulate.Fix because resolver adopts trim ring, need shut down when regulating at every turn and unclamp trim ring resolver is regulated, need fixedly trim ring before the electric rotating machine.Its process is more loaded down with trivial details, and the time is long, and fastening and dismounting causes the screwed hole filigree easily back and forth.
The utility model content
The purpose of this utility model provides a kind of resolver zero-bit adjusting device, and the adjustment process that solves the prior art existence is more loaded down with trivial details, and long problem of time.
The technical solution of the utility model, resolver zero-bit adjusting device, comprise resolver and zero-bit regulating part, the centre of zero-bit regulating part is provided with endoporus, the marginal portion is provided with grabs groove, and the resolver stator is fastened in the endoporus of zero-bit regulating part, by the described groove rotation zero-bit regulating part of grabbing, the rotation of driven rotary transformer, thus zero-bit found.
Characteristics of the present utility model also are:
The zero-bit regulating part is provided with the installing hole for fastening resolver, can directly carry out fastening after having regulated.
The utlity model has following beneficial effect:
1, the utility model resolver stator is fastened in the zero-bit regulating part endoporus, by the rotation of resolver zero-bit adjusting device driven rotary resolver stator, detects by external instrument, thereby finds zero-bit quickly and accurately.
2, the utility model is simple in structure, and is easy to operate, safe and reliable.
Description of drawings
Fig. 1 is the utility model resolver zero-bit adjusting device structural representation;
Fig. 2 is Fig. 1 end view;
Fig. 3 is that the utility model resolver zero-bit adjusting device zero-bit regulating part cooperates schematic diagram with resolver.
Among the figure, 1. resolver, 2. the zero-bit regulating part is 3. grabbed groove, 4. endoporus, 5. installing hole.
Embodiment
Resolver zero-bit adjusting device referring to Fig. 1 and Fig. 2, comprises resolver 1 and zero-bit regulating part 2, and resolver 1 stator is fastened in the endoporus 4 of zero-bit regulating part 2, and zero-bit regulating part 2 is provided with grabs groove 3 and installing hole 5.
Referring to Fig. 3, the endoporus 4 of zero-bit regulating part 2 and resolver 1 stator cylindrical match, make resolver 1 embedded and be clamped in the endoporus 4 of zero-bit regulating part 2, regulate the angle of zero-bit regulating part 2 by grabbing groove 3, by rotating 1 rotation of zero-bit regulating part 2 driven rotary transformers, detect by outer external instrument, thereby quick and precisely to finding zero-bit, finish zeroing.Directly carry out fastening by 5 pairs of resolvers of installing hole and zero-bit adjusting device again.
Claims (2)
1. resolver zero-bit adjusting device, it is characterized in that: comprise resolver (1) and zero-bit regulating part (2), the centre of zero-bit regulating part (2) is provided with endoporus (4), the marginal portion is provided with grabs groove (3), resolver (1) stator is fastened in the endoporus (4) of described zero-bit regulating part (2), by described groove (3) the rotation zero-bit regulating part (2) of grabbing, driven rotary transformer (1) rotation, thus find zero-bit.
