Description

Technical Field

[0001] This utility model relates to the field of rotary transformer technology, and specifically to a rotary transformer adjustment device. Background Technology

[0002] The zero position of a rotary transformer refers to the position where the induced voltage in the sinusoidal output winding is the minimum. At this point, the relative position of the stator and rotor is the electrical zero position, and the output angle is zero degrees. The zero position of a conventional rotary transformer is adjusted by designing a waist-shaped hole on the housing flange. This design can only adjust the position to a limited angle, and it cannot achieve precise positioning. Even after adjustment, the deviation of the zero position is still within a few degrees. Therefore, it can only meet the requirements of rotary transformers with low zero position requirements.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0028] like Figures 1 to 6 As shown, a rotary transformer adjustment device is used to adjust the zero position of a rotary transformer 10. It includes a housing 2 with a gear disk 1, a movable flange 3 fitted onto one end of the housing 2 and equipped with a first flange block 31, a pressure block 5 mechanically connected to one side of the first flange block 31, and an adjusting gear 4 disposed between the first flange block 31 and the pressure block 5. The gear disk 1 and the adjusting gear 4 mesh with each other. The housing 2 is fixed for inserting the rotary transformer 10. Rotating the adjusting gear 4 causes the housing 2 to drive the rotary transformer to rotate via the gear disk 1. In this embodiment, the first flange block 31 is used to fix the positions of the gear disk 1 and the adjusting gear 4, so that the adjusting gear 4 and the pressure block 5 are fixed in position via the movable flange 3, ensuring position accuracy while also providing freedom of movement in the circumferential direction. In actual operation, by setting the adjusting gear 4 and the housing 2 to cooperate, the user rotates the angle of the adjusting gear 4, causing the housing 2 to rotate in conjunction. The housing 2 then drives the rotary transformer 10 to rotate, thereby changing the relative position between the stator and rotor of the rotary transformer, thus achieving the adjustment of the zero position.

[0029] It is worth noting that the housing 2 and the gear disk 1 are an integral structure, and the gear disk 1 is located on the outside of the housing 2. The integral structure can effectively enhance the stability of the structure of this embodiment.

[0030] One end of the adjusting gear 4 is provided with a main rotating shaft 40, and the other end of the adjusting gear 4 is provided with a sub-rotating shaft 41. One end of the sub-rotating shaft 41 is provided with a groove 42. The first flange block 31 is provided with an opening 30, and the pressure block 5 is provided with an opening 50. In this embodiment, both the main rotating shaft 40 and the sub-rotating shaft 41 are fixedly connected to the adjusting gear 4. The opening 30 is for the main rotating shaft 40 to pass through and the main rotating shaft 40 can rotate within the opening 30. The opening 50 is for the sub-rotating shaft 41 to pass through and the sub-rotating shaft 41 can rotate within the opening 50. By setting the main rotating shaft 40 and the sub-rotating shaft 41 to cooperate with each other, it is convenient for the user to rotate the adjusting gear 4 through the groove 42 on the main rotating shaft 40, reducing the operation difficulty of this embodiment.

[0031] One end of the pressure block 5 is provided with an abutment block 51 with a second screw hole 52, and one side of the first flange block 31 is provided with a first screw hole 33 that is screwed to the second screw hole 52. By screwing the second screw hole 52 and the first screw hole 33 together, the connection structure between the pressure block 5 and the first flange block 31 can be effectively fixed, preventing the pressure block 5 from falling off the first flange block 31.

[0032] The movable flange 3 has several second flange blocks 32 on one side. The end of the movable flange 3 with the second flange blocks 32 is used for assembly with the system mechanism, thereby facilitating the fixing of the position of the resolver transmitter and making it convenient for users to use.

[0033] Working principle: The user rotates the adjustment gear 4 to make the housing 2 rotate in conjunction, which in turn drives the rotary transformer 10 to rotate, thereby changing the relative position between the stator and rotor of the rotary transformer, that is, realizing the adjustment of the zero position.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
