制动器是用来使机械运动快速停止的一种装置。目前在起重运输机械。建筑机械等机器的制动装置中,常用的为外抱块式制动器(也有用带式止逆器的)。这种制动器是依靠装在外部弹簧的弹力进行紧闸制动。由于弹簧、推杆等件装在外部,在工作中,要经常清理制动器上的有尘物,给维修带来不便;弹簧在大气中和有腐蚀性物质的环境中锈蚀较快,弹簧过早失去弹力;而且还要专门安装制动器的机座,体积也较大,同时要经常调节弹簧力,使用寿命受到限制。而在我厂的一台机器的行走机构中,安装的是一种较新型的密封式内簧电磁制动器,它装在普通减速机的输入轴端上,实际使用效果较好。现简介如下:
Brake is a device used to quickly stop mechanical movement. Currently lifting the transport machinery. Construction machinery and other machinery brake devices, commonly used for the outer block brake (also useful tape anti-adversary). This type of brake relies on the elastic force of an external spring to brake a brake. Due to the spring, putter and other parts installed in the outside, in the work, to regularly clean the brake on the dust, to repair inconvenience; spring in the atmosphere and corrosive substances in the environment faster corrosion, spring premature Lost elasticity; but also special installation brake base, the volume is also large, and often to adjust the spring force, the service life is limited. In my factory, a machine running gear, the installation is a newer type of sealed inner spring electromagnetic brake, which is mounted on the input shaft end of a common reducer, the actual use of better. The brief introduction is as follows:
