游动天轮在煤矿时有应用,或因地质条件限制,或因安装时设备变更,造成卷筒主轴自天轮设置点距离过近,使偏角远大于1°30＇,这时用游轮则可简便地解决。如图1,0点为满足1°30＇的天轮设置点。0＇点为不符合要求的天轮设置点,B 为游轮游动点,则α_3>α_2>α_1=1°30′成立,下面具体分析游轮的游动条件及对偏角的影响。
Traveling days in the coal mine applications, or due to geological constraints, or due to changes in the installation of equipment, resulting in reel mandrel from the setting point of the wheel too close, so that the declination is much larger than 1 ° 30 ’, then the cruise ship You can easily solve. As shown in Figure 1, point 1 is the setting point of the heaven wheel that meets 1 ° 30 ’. 0 “is the setting point of the demachine wheel, and” B "is the swimming point of the cruise ship, then α_3> α_2> α_1 = 1 ° 30 ’is established. The following is a detailed analysis of the cruising conditions and the influence on the declination angle.
