This class formation be with lubricant applying to the rolling tread, oiling agent causes the amounts of lubrication of being stained with on the chain type rolling element on the low side all on the rolling tread, still can not well solve the long-acting lubricated of chain type rolling element.
The model utility content
The technical problems to be solved in the utility model is: overcome the bad technical problem of prior art cathetus guide rail lubrication effect, a kind of linear rail with long-acting lubrication effect is provided, directly lubricate the chain type rolling element, reduce the use amount of lubricant grease, and realize permanently effective lubricating, reduce maintenance workload.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of linear rail with long-acting lubrication effect, comprise track and slide block, be provided with the chain type rolling element in the described slide block, has the rolling tread that matches with the chain type rolling element on the track, the two ends of described slide block are equipped with recoverable capsule, slide block and recoverable capsule form the circulation loop for chain type rolling element shuttling movement, offer accommodating chamber near the circulation loop place on the described recoverable capsule, the lubricant grease supplier is installed in the described accommodating chamber, described oil feeding device comprises the applicator that receives lubricant grease, and described applicator contacts with the chain type rolling element.When the chain type rolling element rolls, contact with applicator, thereby lubricant grease is coated on the chain type rolling element, realize long-acting lubricated.
As preferably, described applicator is foam body, and described foam body is coated with one deck cotton.Receive lubricant grease on the foam body, when chain type rolling element contact foam body, lubricant grease is coated on the chain type rolling element, for prolonging the working life of foam body, avoid foam body to cause wearing and tearing the output chip because of long-term the contact with the chain type rolling element, influence normal operation of blocks, and outside foam body, coat one deck cotton, to increase the service life.
Further, for increasing the amount of lubricant grease, realize the lubricated of longer time, the volume of described accommodating chamber is greater than the volume of applicator, and the space between accommodating chamber and the applicator is filled with lubricant grease.This structure can make lubricant grease be kept in the space between accommodating chamber and the applicator, and along with the consumption of the lubricant grease in the applicator, that does not stop adds in the applicator, can realize the lubricated of longer time.
Further, for ease of adding lubricant grease, offer on the described recoverable capsule with accommodating chamber and be connected for the passage that drips lubricant grease, the passway of described passage is provided with the screw plug for closed channel.After the lubricant grease in the accommodating chamber uses up, turn on screw plug, inject the screw plug of screwing on after the lubricant grease in the passage.
The beneficial effects of the utility model are, linear rail with long-acting lubrication effect of the present utility model, simple in structure, be easy to make, in recoverable capsule, set up the lubricant grease supplier, can directly lubricant grease be coated on the chain type rolling element, realize the long-acting lubricated of chain type rolling element, and can reduce the consumption of lubricant grease, reduce maintenance workload.The wearing and tearing of less chain type rolling element, the working life of prolongation linear rail.
