Description
Technical field
The utility model relates to cardan shaft lubrication system field, is specially a kind of cardan shaft automatic lubricating system.
Background technique
Cardan shaft is to use the most general transmission part at industrial field, in the heavy industry industry, such as industries such as metallurgy, cement, electric power, uses in a large number the low-speed heave-load cardan shaft.The driving torque that the low-speed heave-load cardan shaft carries and transmission power are very large, therefore the two ends hinge point of low-speed heave-load cardan shaft needs well continuous supplying to the lubricant grease of design appointment, to guarantee forming good oil film support between each friction pair, thereby effectively reduce friction secondary wearing and tearing, the working life of improving cardan shaft.
Because the restriction of the principles and structure of cardan shaft, the auto lube of cardan shaft hinge point (being friction pair) does not have fine solution all the time as a world-famous puzzle but for a long time.Because cardan shaft is when work, need on the one hand continuous forward and reverse rotation, on the other hand, according to equipment operation needs, the one or both ends of cardan shaft also need to move up and down in continuous rotation, and this performance characteristic of cardan shaft has caused and has been the difficult problem of the two ends hinge point of low-speed heave-load cardan shaft (being friction pair) continuous supplying to lubricant grease just.As adopt the ground lubrication station to supply with grease, then lubricating pipe can't be routed to cardan shaft and gets on; If lubricating fitting is installed on the cardan shaft, then the power of lubricating fitting can't be supplied with.
The general way of factory is to pass through the regularly artificial lubricating oil filling fat of grease fitting behind the equipment downtime at present, and the consequence of doing like this is: owing to needing equipment downtime charging-up lubricant oil fat, reduced equipment operation rate; Increased labor strength; Main is charging-up lubricant oil fat in this way, since equipment in running lubricant grease without pressure, can't form good oil film at each friction pair of cardan shaft articulating point and support, very easily cause the dry friction of each friction pair, thereby cause the early failue of friction pair to damage.
Take the cross slider type cardan shaft that adopts on many jobbing sheet-rolling mills at home at present as example, do not supply with way owing to there being well feasible lubricant grease, the consumption of the copper shoe on one rolling mill in the cross slider type cardan shaft is worth and just reaches up to ten million units, thereby causes great waste and loss.Thereby the utmost point is necessary to study a kind of cardan shaft automatic lubricator, to solve the self-lubricated difficult problem of cardan shaft.
