Embodiment Construction

[0019] See attached figure 1 , 2 3. The structure of the diagonal contact bearing of the conjoined set of the present invention includes a rotating shaft 3, a bearing A1 and a bearing B2. The two bearings are sleeved on the rotating shaft 3 side by side with a gap between them. The rotating shaft 3 is provided with two pairs A positioning element for axial positioning of the bearing. These two bearings are angular contact bearings, and the steel balls 2 in them are arranged opposite to the contact angle of the inner ring raceway. A spacer is provided on the outer circumference of the rotating shaft 3, and the spacer is located between the two bearings and is used to separate the two bearings.

[0020] The spacer is a spring 5, and the spring 5 is made of spring steel. The cross-sectional surface of the spring steel bar is rectangular, and the size of the spring steel bar along the axial direction of the spring 5 is larger than the size along the radial direction of the spring 5. ...

Abstract

The invention discloses a connected paired angular contact bearing, which solves the problems that the prior connected paired angular contact bearing is mounted inconveniently, has poor work stability caused by structure qualification and easily has larger reading error generated by a miniature high-speed meter. A structure of the connected paired angular contact bearing comprises a rotating shaft and two angular contact bearings parallelly arranged on the rotating shaft, wherein a gap is reserved between the two bearings along the axial direction of the rotating shaft; and a partition piece used for limiting axial movement of the bearings is arranged between the two bearings on the periphery of the rotating shaft. The rotating shaft is provided with a positioning piece used for carrying out axial positioning on the bearings. The connected paired angular contact bearing is characterized in that the partition piece is a spring, and two end parts of the spring act on the inner lateral surfaces of outer rings of the two bearings respectively.

Description

Technical field [0001] The invention relates to an angular contact bearing, in particular to a conjoined diagonal contact bearing used in a miniature high-speed instrument motor. Background technique [0002] Bearings are generally required to be installed on micro high-speed instrument motors to facilitate the transmission of shaft power. Conjoined diagonal contact bearings are the most commonly used transmission components in micro high-speed instrument motors. The readings produced during the working process of micro high-speed instruments Accuracy is related to the working stability of the relevant transmission components. The structure of the existing conjoined angular contact bearing includes a rotating shaft and two angular contact bearings installed side by side on the rotating shaft. The two bearings are respectively sleeved on the rotating shaft with a certain gap between them and passing through a positioning member. Make them axially fixed on the shaft. The contact an...
