Description
Technical field
The utility model belongs to centrifugation machinery technical field, is specifically related to cup-shaped belt pulley vertical shaft supporting of a kind of disk centrifuge and lubrication system.
Background technology
Disk centrifuge is a kind of widely used separation machinery, and its critical piece is a rotary drum that has taper video disc group and nozzle, and rotary drum is vertically installed, and rotates at a high speed during seperator work, utilizes centrifugal action to realize feed separation.Disk centrifuge general using motor drives rotary drum by gear drive or belt transmission, and the rotating shaft that is connected with rotary drum is called vertical shaft.
Belt transmission structure is simple, certain buffer shock-absorbing effect is arranged, it is the developing direction of present disk centrifuge transmission, its shortcoming is that common dish type belt pulley all adopts cantilevered fashion to install, the tensile force of belt can apply bigger bending load to vertical shaft, and influences the life-span of the fatigue strength and the bearing of vertical shaft; In addition, belt and belt wheel surface can not contact lubricated oil, and the lubrication system more complicated of vertical shaft bearing needs to adopt the mode of oil pump circulating lubricating usually.
Summary of the invention
In order to overcome the deficiency of existing vertical shaft of disc-type separator belt transmission structure, the utility model aims to provide a kind of bending load that can effectively reduce disk centrifuge belt transmission pretightning force to the vertical shaft generation, improve bearing life, and the vertical shaft of disc-type separator belt transmission structure of good lubrication can be provided the rolling bearing on the axle.
The purpose of this utility model is achieved through the following technical solutions:
Cup-shaped belt pulley vertical shaft supporting of a kind of disk centrifuge and lubrication system, comprise belt pulley, vertical shaft, vertical shaft nut, key, bearing block, cylinder roller bearing, angular contact ball bearing group, lubricator cup, lubricating cup support, lubricating oil pipe, fuel inlet fitting, return tray, delivery connection.Belt pulley on the vertical shaft of disc-type separator is cup-shaped, and rim of a cup is vertically installed down, be connected on the axis hole by the bottom and key and the vertical shaft, and by vertical shaft nut check; Vertical shaft is bearing on the bearing block by rolling bearing, and top is cylinder roller bearing, and the bottom is the angular contact ball bearing group, and separator drum is installed in the vertical shaft bottom.Owing to adopt cup-shaped belt pulley to replace the dish type belt pulley, the position of close top cylinder roller bearing adjusted to from axle head in the belt tension place of application of force, thereby effectively reduced the bending load on the vertical shaft.During seperator work, the load of vertical shaft vertical direction is very little, is born by lower angle contact ball bearing group; The cylinder roller bearing bearing capacity is strong, bears main transverse load, thereby improves the life-span of block bearing.
The working speed of vertical shaft of disc-type separator is up to 4000～20000 rev/mins, requires bearing portion is adopted lubricating oil continuous lubrication, because cup-shaped belt pulley is bearing block top complete closed, conventional lubricating method is difficult to implement.A kind of bearing lubrication structure that adopts high-order lubricating cup has been proposed in the technical solutions of the utility model, lubricator cup is passed through on the lubricating cup support installation shaft bearing, make the interior lubricated pasta pasta of lubricating cup be higher than cylinder roller bearing, with the fuel inlet fitting on lubricating oil pipe connection lubricator cup and the bearing block bottom oil-in.During seperator work, lubricating oil in the lubricating cup flows into bearing block through oil-in, and in high-order lubricating cup under the effect of lubricating oil self pressure, oil duct through bearing block inside, flow out from the outlet that is positioned at the cylinder roller bearing top, earlier the cylinder roller bearing bearing is lubricated, then under the effect of gravity, the angular contact ball bearing group of bottom of flowing through is lubricated, and the oil return opening from the return tray bottom flows out at last.Should lubricated scheme not need oil pump, simple in structure, reliable operation also has volume control device on the lubricator cup, can adjust flow rate of lubricating oil as required.
The drive mechanism that the present invention proposes also can be used for other plant equipment and separates in the belt drive unit.
