The invention relates to a tractor. The tractor comprises a front support seat and a rear support seat, and a spindle mounted in the front support seat and the rear support seat, which is movably mounted in the front support seat and the rear support seat. A traction guide wheel is mounted at the position between the front support seat and the rear support seat; a stator component is installed in the rear support seat, a rotor component is installed at the rear end of the main shaft, a drum brake component is installed at the front end of the rear support seat, and a traction guide wheel is mounted on the rear support seat. There is a cylindrical surface matched with the drum brake. The front support seat, the lower part of the rear support seat, and the front support seat and the rear support seat are respectively provided with a chassis. The front and rear support seats are separately arranged and connected through the chassis. The frame and the spindle are combined and matched according to different load and speed tractor. Only one set of casting die is needed to produce a variety of tractor models with load of 1000 10000kg and speed of 0.5 5m/s. The cost of mould development has been greatly reduced. The main bearing has large load capacity. The traction guide wheel and brake wheel are cast as a whole, which is safe and reliable.
【技术实现步骤摘要】
鼓式双支撑组合式高速重载曳引机
本专利技术涉及一种电梯牵引动力装置,尤其是一种鼓式双支撑组合式高速重载曳引机。
技术介绍
曳引机是通过钢丝绳连接并牵引电梯的电梯牵引动力装置,是电梯轿厢能够升降运行的动力来源,现有的曳引机一般包括机座和设于机座上的曳引轮、主轴、转子和定子,其中,根据转子和定子的配合结构不同一般可分为内转子结构的曳引机和外转子结构的曳引机。在散热要求较高的使用场景中,一般使用外转子曳引机,现有的外转子曳引机的结构一般有大载重高速曳引机悬臂和双支撑结构,悬臂结构存在主轴承载小,机座变形大,模具不能通用的缺点。主要用于小载重电梯。市场上现有的双支撑结构曳引机主要有两种结构,一种是双支曳引轮,采用碟刹制动,另外一种是双支曳引轮和转子,采用鼓式或碟刹制动。均存在以下缺点,双支曳引轮,碟刹制动曳引机存在加工困难,总体成本过高,安装维护不方便。另外一种双支曳引轮和转子,采用鼓式或碟刹制动曳引机,主轴承载小,功率密度低,散热差。
