Embodiment Construction

[0042] A lubricating system according to a first embodiment of the present invention is shown in Figure 1; This includes a movable piston 2.1 pushed by an electromagnet to dampen the compression spring force. A spring-loaded check valve 2.4 is arranged opposite the piston 2.1. This piston 2 . 1 presses the lubricant, which in the typical embodiment comprises lubricating or synthetic oil, from the extraction side of the pump 2 to the pressure side. The spring-loaded check valve 2.4 enables precise and exact dosing of lubricant. In addition, backflow of lubricant from the lubricant line 4 is prevented by means of the spring-loaded check valve 2.4. A precise and exact dosing is ensured or ensured by means of the piston stroke against the spring-loaded check valve 2.4. The pressure level is maintained by the spring of the spring-loaded check valve 2.4 and achieves constant lubricant pressure.

[0043] If the electromagnet pushes or moves the piston 2 . 1 forward or to the pres...

Abstract

A lubrication system for a transportation system and, in particular for an escalator or a moving walk, has a piston pump for delivering a prescribed quantity of lubricant per work cycle, an arrangement of lubrication points with at least one lubrication point and a branched lubricant pipeline. Each branch of the lubricant pipeline connects the pump in parallel to a lubricating point of the arrangement of lubrication points. Through a valve arrangement each branch of the lubricant pipeline can be selectively and individually blocked or connected to the piston pump.

Description

technical field [0001] The present invention relates to a system and method for lubricating conveying systems, in particular escalators or sliding walks. Background technique [0002] An escalator includes a plurality of steps connected together by one or more endless step chains. Furthermore, in the transport area, the steps are vertically offset with respect to each other and thus enable vertical transport. Sliding walks consist of multiple pallets held together by one or more endless pallet chains for the horizontal transport of people and / or light items. In both transport systems it is also possible to provide handrails driven by handrail chains. The step chain or pallet chain and handrail chain, respectively, can be coupled by one or more drive units, in particular with one or more main drive chains with one or more drive units, in particular sprockets driven by electric motors. The individual chains typically have different dimensions (in particular the number of li...
