When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered 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 7 As shown, a resolver transmitter includes a housing 1 with an assembly cavity 11, a housing 3 disposed within the housing 1, a rotating shaft 4 disposed within the housing 3, a stator winding 5 and a rotor winding 6 sleeved on the rotating shaft 4, a tail cover 7 sleeved on one end of the housing 1, and a sealing ring 9 disposed between the tail cover 7 and the housing 1. A groove 10 for engaging the sealing ring 9 is provided on one side of the housing 1, and the sealing ring 9 is provided with a grease coating. An opening 2 for the rotating shaft 4 to pass through is provided at one end of the housing 1, and one end of the rotating shaft 4 passes through the housing 1 through the opening 2 and extends to the outside of the housing 1. It is worth noting that the sealing ring 9 is made of rubber. By providing a rubber material support for the sealing ring 9 between the housing 1 and the tail cover 7, the airtightness between the tail cover 7 and the housing 1 can be enhanced. Furthermore, by providing the grease coating, the airtightness between the housing 1 and the tail cover 7 is further enhanced, effectively preventing the entry of foreign matter or fluid in this embodiment, thereby improving the use effect of this embodiment.

[0029] A groove 31 is provided at one end of the assembly cavity 11, and a main bearing 32 for being mounted on the rotating shaft 4 is provided in the groove 31. A sub-groove 33 is provided at one end of the groove 31, and a sealing ring 8 for being mounted on the rotating shaft 4 is provided in the sub-groove 33. It should be noted that the groove 31, the sub-groove 33 and the opening 2 are all located on the same axis, the groove 31 is provided inside the end of the outer shell 1 close to the opening 2, and a grease coating is provided on the surface of the sealing ring 8. By providing the grease coating, on the one hand, the airtightness of the outer shell 1 is enhanced to prevent external foreign matter from entering the outer shell 1 through the opening 2. On the other hand, by applying the grease coating, the friction between the rotating shaft 4 and the sealing ring 8 can be effectively reduced, thereby improving the implementation effect of this embodiment.

[0030] Furthermore, a rear cover 12 is snapped onto one end of the housing 1, and the rear cover 12 is used to close the assembly cavity 11; by providing the rear cover 12, the airtightness of this embodiment is further enhanced; it is worth noting that a mounting groove 13 with a secondary bearing 14 is provided on the rear cover 12, and an opening 15 is provided at one end of the mounting groove 13 that passes through the rear cover 12, and one end of the rotating shaft 4 passes through the rear cover 12 through the opening 15, so that the secondary bearing 14 is sleeved on one end of the rotating shaft 4.

[0031] Furthermore, a decoder 71 is provided between the tail cover 7 and the rear cover 12 . A connection port 72 for correspondingly connecting to the shaft 4 is provided at the center of the decoder 71 . One end of the shaft 4 passes through the rear cover 12 and is connected to the decoder 71 through the connection port 72 .

[0032] Working principle: By arranging a sealing ring 9 between the tail cover 7 and the outer shell 1 and applying grease on the sealing ring 9, the connection structure between the tail cover 7 and the outer shell 1 is reinforced, and the air tightness between the tail cover 7 and the outer shell 1 is enhanced. By arranging a sealing ring 8 with a grease coating in the sub-groove, on the one hand, the airtightness of the outer shell 1 is enhanced to prevent external foreign matter from entering the outer shell 1 through the opening 2. On the other hand, by applying the grease coating, when the rotary transmitter rotates, the rotating shaft 4 abuts against the grease coating, which can effectively reduce the friction between the rotating shaft 4 and the sealing ring 8, thereby improving the implementation effect of this embodiment.
