The Application of RU42, RU66 cross roller bearings on drone Pan-Tilt-Zoom camera platform control

The drone pan-tilt head is a stable platform installed on a drone, used to keep the Pan-Tilt-Zoom camera or other equipment level or stable.

According to its rotation characteristics, drone platform tripod head can be divided into horizontal rotating gimbals that can only rotate left and right, and omnidirectional platforms that can rotate both left and right as well as up and down.

Generally speaking, the horizontal rotation angle is 0 ° to 350 °, and the vertical rotation angle is+90 °. The horizontal rotation speed of the constant speed platform is generally between 3 ° and 10 °/s, and the vertical speed is around 4 °/s. The horizontal rotation speed of the variable speed gimbal is generally between 0 ° and 32 °/s, and the vertical rotation speed is around 0 ° and 16 °/s. In some high-speed Pan-Tilt-Zoom camera systems, the horizontal rotation speed of the gimbal is over 480 °/s, and the vertical rotation speed is over 120 °/s.

The outdoor environment experiences significant changes in temperature and is susceptible to erosion from rain or moisture. Therefore, outdoor gimbals are generally designed to be sealed and rainproof. In addition, the outdoor gimbal also has high torque and choke protection circuits to prevent the gimbal from forcibly starting and burning out the motor when it freezes. In harsh low-temperature conditions, a temperature controlled heater can also be installed inside the gimbal.

In order to meet the urgent needs of large-scale industrial monitoring, the company has begun to develop high-precision, high-performance, high reliability, and high adaptability bearings to meet the needs of various high-end gimbals. When the gimbal is in operation, it cannot rotate up, down, left, or right. Instead, it is driven by a motor and supported by bearings to control and rotate. Therefore, the gimbal support bearing is a key component of the gimbal's performance. In terms of bearing development, many Pan-Tilt-Zoom camera platform manufacturing companies use cross roller bearings to design and manufacture high-end gimbals, and use small-sized cross roller bearings to simplify the gimbal structure. Thin walled cross roller bearings RA1008, RU42, RU66, etc. with high precision, low friction torque, and strong adaptability to high and low temperatures have been well applied in many high-end gimbals.
