The invention relates to a gap-adjustable rotary speed reducer for a tower crane, which comprises a rotary speed reducer mounting flange, a high point mark and a plurality of connecting holes, and the eccentric design of the connecting holes enables a user to adjust the backlash by rotating the position of the rotary speed reducer so as to ensure that the rotary motion of the tower crane is stable and safe. Meanwhile, a plurality of groups of hole sites with deflection angles are machined on the flange, so that the backlash adjusting range is further expanded, and more adjusting options are provided. According to the technical scheme, by effectively adjusting the backlash, the stability and safety of rotation of the tower crane are improved, the service life of equipment is prolonged, operation noise and energy consumption are reduced, and the backlash adjusting device has high practical value and wide application prospects.

    本发明涉及一种可调间隙的塔机用回转减速器,包括回转减速器安装法兰、高点标记和多个连接孔,连接孔的偏心设计使得通过旋转回转减速器位置,用户能够调节侧隙,确保塔机的回转运动平稳、安全。同时,本发明还通过在法兰上加工多组偏转角度的孔位,进一步扩展了侧隙调整范围,提供更多调节选项。该技术方案通过有效调节侧隙,不仅提高了塔机回转的平稳性和安全性,延长了设备使用寿命,还降低了运行噪音和能耗,具有较高的实用价值和广泛的应用前景。
