Abstract
The invention relates to the technical field of engineering pumps, in particular to a self-lubricating sliding bearing device for long pump shafts. The self-lubricating sliding bearing device is provided with a pump shaft and a bearing pedestal and is characterized in that a shaft sleeve, a Thordon bearing and a bearing sleeve are sequentially arranged between the pump shaft and the bearing pedestal in a sleeved mode. The shaft sleeve is fixedly connected with the pump shaft in a sleeved mode. The inner circle of the Thordon bearing is fixedly connected with the shaft sleeve so as to locate the bearing in the radial direction. The outer circle of the Thordon bearing is fixedly connected with the bearing sleeve through screws. The bearing sleeve is fixedly connected with the bearing pedestal through set screws with cone points. Through the adoption of the structure, the self-lubricating sliding bearing device for the long pump shafts has the advantages of being reasonable in design, reliable in structure, convenient to use, small in bearing friction system, low in power consumption, high in transmission efficiency, easy to machine, resistant to corrosion, high in wear resistance, good in lubricating effect and the like.
Description
Technical field
The present invention relates to pump for engineering technical field, specifically a kind of pump class major axis self-lubricating plain bearing device.
Background technique
Traditional pump apparatus is for the bearing using on major axis, be generally sliding bearing, the deficiency of this sliding bearing is: pivot friction coefficient is large, power consumpiton is many, passes to that efficiency is low, heating value is large, and lubricated maintenance inconvenience, expend oiling agent, its load, rotating speed and operating temperature accommodation are narrow, and a small amount of variation of working condition is larger to the performance impact of bearing.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of reasonable in design, reliable in structure, easy to use, pivot friction system is little, power consumpiton is low, transmission efficiency is high, easy processing, corrosion-resistant, wear-resisting property is high, the pump class major axis self-lubricating plain bearing device of high lubricating effect.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of pump class major axis self-lubricating plain bearing device, be provided with pump shaft and bearing support, it is characterized in that being arranged with successively between pump shaft and bearing support axle sleeve, thordon bearings and bearing housing, axle sleeve and pump shaft are fixedly sleeved, thordon bearings inner circle is fixedly connected with axle sleeve, be beneficial to radial location bearing, cylindrical is fixedly connected with bearing housing through fastening screw trip bolt, bearing housing is fixedly connected with through cone end Cock screw with bearing support, in the time that pump shaft turns round, the slidingsurface of thordon bearings is directly contacted by the undeveloped life of moisture, frictional loss and surface losses are greatly reduced, simultaneously, the moisture film forming in operation process also has certain damping capaicty, and, can also form dry startup, without independent water filling in the situation that, dry running 100S left and right.
The present invention, owing to adopting said structure, has the advantages such as reasonable in design, reliable in structure, easy to use, pivot friction system is little, power consumpiton is low, transmission efficiency is high, easy processing, corrosion-resistant, wear-resisting property is high, high lubricating effect.
accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Reference character: cone end Cock screw 1, bearing support 2, thordon bearings 3, bearing housing 4, axle sleeve 5, pump shaft 6.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of pump class major axis self-lubricating plain bearing device, be provided with pump shaft 6 and bearing support 2, it is characterized in that being arranged with successively axle sleeve 5 between pump shaft 6 and bearing support 2, thordon bearings 3 and bearing housing 4, axle sleeve 5 is fixedly sleeved with pump shaft 6, thordon bearings 3 inner circles are fixedly connected with axle sleeve 5, be beneficial to radial location bearing, cylindrical is fixedly connected with bearing housing 4 through fastening screw trip bolt, bearing housing 4 is fixedly connected with through cone end Cock screw 1 with bearing support 2, in the time that pump shaft 6 turns round, the slidingsurface of thordon bearings 3 is directly contacted by the undeveloped life of moisture, frictional loss and surface losses are greatly reduced, simultaneously, the moisture film forming in operation process also has certain damping capaicty, and, can also form dry startup, without independent water filling in the situation that, dry running 100S left and right.
The present invention, owing to adopting said structure, has the advantages such as reasonable in design, reliable in structure, easy to use, pivot friction system is little, power consumpiton is low, transmission efficiency is high, easy processing, corrosion-resistant, wear-resisting property is high, high lubricating effect.
