The invention discloses a lead screw elevator, and relates to the field of lead screw elevators, the lead screw elevator comprises a bottom box and a lifting plate, the two ends of the top surface of the bottom box are rotationally connected with rotating gears, the top surface of the bottom box is provided with a driving mechanism matched with the rotating gears, and the two ends of the top surface of the bottom box are connected with outer sleeves rotationally connected with the rotating gears respectively. The oil outlet pipe connected with the middle section of the top of the bottom box is connected to the outer sleeve, and the oil inlet pipes connected with the two ends of the bottom box are connected to the inner sleeve, so that lubricating oil in the outer sleeve and lubricating oil in the bottom box form circulation; and meanwhile, clean lubricating oil filtered by the filter screen enters the inner sleeve through the oil inlet pipe to lubricate the screw rod, so that the abrasion of the dust to the screw rod is prevented from being enhanced, and the service life of the screw rod elevator is ensured.

    本发明公开了一种丝杆升降机,涉及丝杆升降机领域,包括底箱与升降板,所述底箱的顶面两端皆转动连接有转动齿轮,且底箱的顶面安装有与转动齿轮配合的驱动机构,所述底箱顶面两端皆连接有分别与每个转动齿轮转动连接的外套筒。本发明通过在外套筒上连接与底箱顶部中段连接的出油管,在内套筒上连接与底箱两端连接的进油管,使得外套筒内部的润滑油与底箱内部的润滑油形成循环,在工作时,螺杆下降,其螺纹上黏附的带灰尘的润滑油被螺纹环挂下,落到内套筒与外套筒之间,由出油管进入底箱,同时经由滤网过滤的干净润滑油通过进油管进入内套筒对螺杆进行润滑,防止灰尘加强对丝杆的磨损,以保证丝杆升降机的使用寿命。
