Description
技术领域technical field
本实用新型涉及旋转转台技术领域，具体涉及一种轨道侧部摩擦驱动旋转转台。The utility model relates to the technical field of rotary turntables, in particular to a rail side friction-driven rotary turntable.
背景技术Background technique
旋转转台大多采用销齿驱动，转台上连接旋转电机，旋转电机驱动主动齿轮自转，主动齿轮与固定的大齿轮啮合，主动齿轮自转过程中驱动转台转动。销齿传动的旋转转台安装精度高，需要将主动齿轮与大齿轮精准啮合，并且旋转驱动过程中不得错位，不适合在展会这样要求高效率、简单安装的场合。Most of the rotary turntables are driven by pin teeth. The rotary motor is connected to the turntable. The rotary motor drives the driving gear to rotate, and the driving gear meshes with the fixed large gear. During the rotation of the driving gear, the turntable is driven to rotate. The pin-tooth-driven rotary turntable has high installation accuracy. It is necessary to precisely mesh the driving gear with the large gear, and it must not be misaligned during the rotational driving process. It is not suitable for occasions such as exhibitions that require high efficiency and simple installation.
对于摩擦驱动旋转转台，在轨道上部放置摩擦轮，只需将摩擦轮放置在轨道上，摩擦轮摩擦力下自转带动转台旋转，搭设简单，组装效率高，但是旋转驱动装置上方的面板需要释放重物，重物负载对旋转驱动装置进行向下的按压，使磨擦轮与导轨之间产生摩擦，摩擦轮自转带动转台旋转，因此轨道上部摩擦驱动旋转转台仅适用于小直径转台。对于大直径转台，由于转台尺寸大，如果在旋转驱动装置上方放置重物，则重心不在转台中心，转台旋转过程中偏心；重物如果放置在转台中心，由于转台尺寸大，则旋转驱动装置上方很难施加重力，摩擦轮与轨道之间的摩擦力小，摩擦轮将自转不起来。For the friction-driven rotary turntable, the friction wheel is placed on the upper part of the track, and only the friction wheel is placed on the track, and the rotation of the friction wheel drives the turntable to rotate under the friction force of the friction wheel. The load of heavy objects presses the rotary drive device downward, causing friction between the friction wheel and the guide rail, and the rotation of the friction wheel drives the turntable to rotate. Therefore, the friction-driven rotary turntable on the upper part of the track is only suitable for small-diameter turntables. For large-diameter turntables, due to the large size of the turntable, if a heavy object is placed above the rotary drive device, the center of gravity is not in the center of the turntable, and the turntable is eccentric during rotation; It is difficult to apply gravity, the friction between the friction wheel and the track is small, and the friction wheel will not rotate.
