Description

Technical Field

[0001] This utility model relates to the field of elastic support transmission technology, specifically to a novel elastic support rubber friction transmission device for an optoelectronic instrument cover. Background Technology

[0002] The photoelectric instrument housing is a special housing designed for the use of astronomical telescopes and photoelectric instruments. This housing can open a skylight and rotate 360°, allowing light from any position in the sky to enter the housing chamber, enabling the photoelectric instrument to complete its working process.

[0003] The main functions of the enclosure for photoelectric instruments are twofold: firstly, to protect astronomical telescopes, photoelectric instruments, and other equipment from the erosion of harsh weather conditions such as rain, snow, and sandstorms, and to provide a good observation environment for observers; secondly, to prevent adverse effects of external temperature changes on observations, ensuring a good seeing (astronomical atmospheric tranquility) during observations.

[0004] Current friction transmission for optoelectronic instrument covers generally uses rigid supports. When the optoelectronic instrument cover rotates using steel wheel friction transmission, the flatness of the base of the optoelectronic instrument cover cannot be guaranteed, and the steel wheel and the base are prone to poor contact. The friction coefficient between the steel wheel and the steel base is relatively small, which is not conducive to transmission. Therefore, the existing technology has significant defects. Utility Model Content

[0005] In order to solve the above-mentioned defects and deficiencies in the prior art, this utility model provides the following.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel elastic support rubber friction transmission device for a photoelectric instrument cover, comprising: a motor, a transmission wheel, and an elastic support device.

[0007] The motor includes a motor body and a drive shaft. A first support wall is provided on the elastic support device, which is placed in parallel and symmetrically. The motor body is fixedly connected to the first support wall, and the drive shaft of the motor passes through the first support wall and is engaged with the drive wheel.

[0008] Furthermore, the elastic support device includes a first base, a second base, and a spring;

[0009] The first base has a position fixing hole, and the second base has a column. The number of position fixing holes on the first base is equal to the number of columns on the second base. The columns pass through the spring and the position fixing hole on the first base in sequence.

[0010] Furthermore, the elastic support device also includes a third base, on which a sleeve is fixedly connected. The center of the connection between the third base and the sleeve has a through hole, which is the same size as the hole in the sleeve and is concentric.

[0011] The number of sleeves on the third base is equal to the number of columns on the second base. The columns pass through the spring and the sleeves on the third base in sequence, and the sleeves pass through the position fixing holes on the first base.

[0012] Furthermore, the first support wall is fixedly connected to the first base.

[0013] Furthermore, a second support wall is also provided on the first base, and the second support wall is parallel and symmetrical to the first support wall.

[0014] The transmission wheel is located between the first support wall and the second support wall, and a support member is fixedly connected to the second support wall. The transmission shaft passes through the first support wall, the transmission wheel, the second support wall and the support member in sequence and is movably connected to the support member.

[0015] Furthermore, the first base and the third base are also provided with a first through hole, and the first base and the third base are connected by bolts passing through the first through hole on the first base and the third base.

[0016] Furthermore, the second base is also provided with a groove, and a second through hole is provided in the groove. The second through hole is used to fix the second base to the bolt.

[0017] Furthermore, the first base, the second base, and the third base are also provided with material holes.

[0018] Furthermore, the transmission wheel is a rubber wheel.

[0019] In this invention, the elastic support rubber friction transmission device for the photoelectric instrument cover uses a rubber friction wheel to ensure the coefficient of friction, and uses an elastic base support to ensure good contact between the base of the photoelectric instrument cover and the rubber wheel.

[0020] The beneficial technical effects achieved by this utility model are as follows: When transmitting power to the photoelectric instrument cover, the rubber wheel and spring device ensure full contact between the transmission device and the photoelectric instrument cover. Even if the flatness of the base of the photoelectric instrument cover cannot be guaranteed, the contact effect between the transmission wheel and the base can still be ensured, and the friction coefficient between the transmission wheel and the steel base is sufficiently large, so as to achieve effective transmission of the photoelectric instrument cover.
