The lubrication system has the advantages of good lubricity, higher safety, rotating flexibility and convenience in maintenance.
Description
Technical field
The invention belongs to concrete pump truck arm connecting rod technology field, especially relate to the lubrication system of concrete pump truck arm connecting rod.
Background technique
In the using process of concrete mixer, in order to ensure lubricating between each moving element, particularly, in order to ensure lubricating between jib, connecting rod oil cylinder, need to configure lubrication system at present; Traditional concrete pump truck arm, the lubricated of connecting rod are the combinations of driving oil hole and annular oil groove or annular and helical oil groove on bearing pin, from end part of pin shaft or connecting rod bearing, oiling cup is beaten lubricating grease inward, on axle, open the intensity that oil groove has reduced axle, there is the danger fractureing, reduced the safety coefficient of jib.In operating process, must first the larger cavity between axle and connecting rod bearing be made for longer bearing pin, then just enter between bearing pin bearing through helical oil groove.Because the cavity between bearing pin and connecting rod bearing is very large, make and not only waste lubricating grease, and these static lubricating grease times are once the long hardening of hardening, the passage leading between axle and bimetallic bearing is blocked, again do not enter lubricating grease, and these knot hardening lubricant greases are attached on axle, greatly increase resistance when axle rotates, axle is rotated dumb; Bimetallic bearing, without flange, packs in connecting rod bearing, the boss in the middle of what its location was leaned on is connecting rod bearing, and this is very painstaking with regard to making to get up as the bearing replacing of easily damaged parts.
Summary of the invention
The object of the invention is to improve the deficiency of prior art and provide that a kind of lubricity is good, Security is higher, rotating the lubrication system for concrete pump truck arm connecting rod flexible, easy to maintenance.
The object of the present invention is achieved like this, a kind of lubrication system for concrete pump truck arm connecting rod, by jib, connecting rod, oil cylinder, the lubrication system that two jibs connect, jib and connecting rod be connected lubrication system and jib and oil cylinder be connected lubrication system composition, be characterized in the lubrication system that two described jibs connect, jib and connecting rod be connected lubrication system and jib is to connect bearing pin to be provided with oiling passage with the lubrication system that is connected of oil cylinder, oil groove on oiling channel connection bearing, lubricant oil is at oiling passage, in oil groove, flow to and need lubricating component.
In order further to realize object of the present invention, the lubrication system that can be two jibs connections is that the inwall of the bearing of two jib joints is provided with screw lubrication oil groove, annular oil groove, one end, inner side sealing of screw lubrication oil groove, one end, outside are opened and are communicated with annular oil groove, the oiling channel connection on annular oil groove and bearing pin.
In order further to realize object of the present invention, can be jib be that the inner ring of the bearing of joint is provided with the screw lubrication oil groove of opening at two ends, the oiling channel connection on helical oil groove and bearing pin with the lubrication system that is connected that is connected lubrication system and jib and oil cylinder of connecting rod.
In order further to realize object of the present invention, it can be described bearing one end flange.
Compared with the prior art the present invention has following distinguishing feature and good effect: the lubrication system that two jibs of the present invention are connected, jib and connecting rod be connected lubrication system and jib is to connect bearing pin to be provided with oiling passage with the lubrication system that is connected of oil cylinder, oil groove on oiling channel connection bearing, lubricant oil is at oiling passage, in oil groove, flow to and need lubricating component, using oil groove by changing on bearing pin on the bearing of easily damaged parts, only on bearing pin, process pouring orifice, intensity and the working life of bearing pin are greatly improved, the form of helical oil groove is designed with different forms according to different portions position, divide and lead to and obstructed two kinds, the unlubricated fat of cavity between connecting rod bearing and bearing pin, having solved the lubricating grease sclerosis of hardening hinders the lubricated and axle rotational resistance of repeatedly buying oil and increases problem, the oiling material-saving that saves time, changing straight flange bearing is one end flange bearing, makes bearing change flange outside fix into by interior location, changes simple and fast, and lubricated impurity can discharge from flange one end by helical oil groove with lubricant oil, lubricated good rotation flexibly, self oiling bearing.
