最近,我们在检修瑞典高速火柴糊盒机时,党得该机配套用的Simplebelt(德国制造)无级变速器性能良好、结构轻巧、调速平稳、变速范围可达1比3。在一般轻载荷的机械设备上有推广价值,特介绍如下。扩涨型挠性变速器(见图1)有两种型式,即标准型(a)和钩爪型(b)。安装时,齿套3(见图2)与电动机轴紧配,轴上的键用紧定螺钉固定,齿套内孔开有油槽,外圆的花键上装有扩涨皮带轮1和2,轮子两侧各由星形弹簧5压紧。端部有注油嘴4,可将黄油注满齿套内腔,使在皮带轮和套简间形成油脂薄膜。
Recently, the Simplebelt (Made in Germany) Continuously Variable Transmission that the party acquired with this machine has performed well, with a light weight structure and a smooth speed adjustment, with a speed range of up to 1 to 3. In the general light-loaded machinery and equipment have promotional value, special introduction is as follows. Expansion of the flexible transmission (see Figure 1), there are two types, namely the standard (a) and claw type (b). During installation, the gear sleeve 3 (see Figure 2) is tightly matched with the motor shaft, the key on the shaft is fixed with the set screw, the oil groove is opened in the inner hole of the gear sleeve, expansion sprockets 1 and 2 are mounted on the splines of the outer circle, Both sides are pressed by a star spring 5. The end of the nozzle 4, butter can be filled cavity, so that in the pulley and sleeve form a thin film between the oil.
