Description

Technical Field

[0001] This application relates to the technical field of resolvers, and specifically to a resolver stator-rotor assembly. Background Art

[0002] A resolver is an electromagnetic sensor, also known as a synchro resolver. It is a small AC motor used to measure angles and is used to measure the angular displacement and angular velocity of the rotating shaft of a rotating object, and is applicable to various fields such as industrial automation, aerospace, etc.

[0003] The working principle of a resolver is based on electromagnetic induction. It mainly consists of two parts: a stator and a rotor. The stator is the stationary part, which includes an excitation winding and an output winding, while the rotor is the rotating part, which includes an induction winding. When the excitation winding is energized, it generates a magnetic field in the stator. When the rotor rotates, the induction winding cuts the magnetic force lines, thereby generating an induced current, and the amplitude and phase of the induced current are proportional to the rotor angle.

[0004] After the wire wiring on the resolver is completed, in order to facilitate installation and save installation space, the output terminals of the resolver are usually parallel to the rotating shaft, that is, horizontal wire outlet; for some application requirements and installation environments that are more complex, vertical wire outlet is required, that is, the output terminals of the resolver are perpendicular to the rotating shaft.

[0005] However, the existing resolvers usually can only have a single-direction wire outlet. When encountering a more complex installation environment, it is difficult to meet the application requirements, resulting in poor flexibility. Therefore, it is necessary to provide a resolver stator-rotor assembly to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a resolver stator-rotor assembly, which achieves that when encountering a more complex installation environment, the operator can select horizontal wire outlet or vertical wire outlet according to the actual situation, meet the application requirements, and improve the installation flexibility.

[0008] The technical solution adopted by this application to solve its technical problems is: a resolver stator-rotor assembly, including:

[0009] A stator core;

[0010] A rotor core, which is aligned inside the stator core;

[0011] A connection skeleton, which is used to electrically connect the stator core and the rotor core, and the connection skeleton has:

[0012] A chassis, which is installed on one side of the stator core;

[0013] A crossbeam frame, which is installed at the upper end of the chassis. The crossbeam frame has at least two groups of baffles. An installation block is installed between the baffles. Installation grooves are provided through the installation block and the baffles. A pin is provided in the installation groove. An upper hole is provided on the pin. A matching hole is horizontally penetrated through the installation block. The upper hole and the matching hole correspond to each other;

[0014] A top cover, at least two groups of wire inlet holes are penetrated through the side end of the top cover, and the wire inlet holes correspond to the matching holes.

[0015] Further, at least two groups of wire laying grooves are provided at the upper end of the top cover. The number of the wire laying grooves corresponds to the number of the wire inlet holes. A wire laying hole is formed between the top cover and the crossbeam frame. The wire laying groove corresponds to the wire laying hole.

[0016] Further, fitting grooves are provided at both side ends of the top cover, and fitting blocks are fixedly installed on both sides of the crossbeam frame. The fitting grooves and the fitting blocks cooperate with each other.

[0017] Further, a bottom ring is provided at the lower end of the stator core, and a housing is provided at the upper end of the stator core. The bottom ring and the housing cooperate with each other.

[0018] Further, the chassis is fixedly installed on one side of the bottom ring, and the top cover is fixedly installed on one side of the housing.

[0019] The beneficial effect of the present application is that: for a resolver stator-rotor assembly provided by the present application, the output terminal can be horizontally led out by passing through the wire inlet hole, the matching hole and the upper hole, or the output terminal can be vertically led out by passing through the wire inlet hole, the wire laying hole and the wire laying groove. When encountering a relatively complex installation environment, the operator can choose horizontal wire leading or vertical wire leading according to the actual situation, meeting the application requirements and improving the installation flexibility.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0037] As Figures 1-2 shown, the present application provides a resolver stator-rotor assembly, including a stator core 1 and a rotor core 2 that is completely aligned inside the stator core 1. A connecting skeleton 3 is fixedly installed on one side of the stator core 1, and the connecting skeleton 3 is used to electrically connect the stator core 1 and the rotor core 2.

[0038] A bottom ring 11 is provided at the lower end of the stator core 1, and a housing 12 is provided at the upper end of the stator core 1. The bottom ring 11 and the housing 12 cooperate with each other to protect the stator core 1. At the same time, the connecting skeleton 3 has a bottom frame 31 fixedly installed on one side of the bottom ring 11. An upper cross beam frame 32 is fixedly installed at the upper end of the bottom frame 31, and the upper cross beam frame 32 is electrically connected to the stator core 1;

[0039] As Figures 3-4 shown, the upper cross beam frame 32 has multiple groups of baffles 321. An installation block 322 is fixedly installed between the multiple groups of baffles 321. An installation groove 323 is formed through the installation block 322 and the baffles 321. A pin 4 is injection-molded in the installation groove 323, and the pin 4 is used to complete the transmission of electricity or signals;

[0040] At the same time, an upper hole 41 is formed in the pin 4, and a mating hole 324 is horizontally formed through the installation block 322. When the pin 4 is injection-molded in the installation groove 323, the upper hole 41 and the mating hole 324 correspond to each other;

[0041] As Figures 1-2 shown, a top cover 33 is fixedly installed at one side end of the housing 12. Mating grooves 333 are formed at both side ends of the top cover 33. At the same time, mating blocks 325 are fixedly installed at both sides of the upper cross beam frame 32. The mating grooves 333 and the mating blocks 325 cooperate with each other. Therefore, when the housing 12 is sleeved on the upper end of the bottom ring 11, the top cover 33 will also be sleeved on the upper end of the upper cross beam frame 32, so that the mating blocks 325 are snapped into the mating grooves 333 to fix the top cover 33;

[0042] And multiple groups of incoming wire holes 332 are formed through the side end of the top cover 33. The incoming wire holes 332 correspond to the mating holes 324. Therefore, the output terminals can be passed through the incoming wire holes 332, the mating holes 324, and the upper holes 41 to achieve horizontal wire outlet;

[0043] At the same time, multiple groups of wire releasing grooves 331 are formed at the upper end of the top cover 33. The number of the wire releasing grooves 331 corresponds to the number of the incoming wire holes 332. And when the top cover 33 is sleeved on the upper cross beam frame 32 (specifically as Figure 3As shown in the figure, a wire threading hole 326 is formed between the top cover 33 and the crossbeam frame 32. The wire threading groove 331 corresponds to the wire threading hole 326. Therefore, the output terminal can pass through the wire inlet hole 332, the wire threading hole 326, and the wire threading groove 331 to achieve longitudinal wire outlet. Thus, when encountering a relatively complex installation environment, the operator can choose horizontal wire outlet or longitudinal wire outlet according to the actual situation to meet the application requirements and improve the installation flexibility.

[0044] As Figures 5-6 shown, a plurality of groups of winding frames 13 are fixedly installed on the inner wall of the stator core 1. An arc plate 14 is fixedly installed at the inner end of the winding frame 13. The arc plate 14 is attached to the inner surface of the rotor core 2. At the same time, a relief groove 15 is provided at both side ends of each winding frame 13. Through the relief groove 15, the winding can be wound from a place near the root, increasing the winding range, preventing adjacent two coils from being affected, and making the winding structure more compact.

[0045] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
