Abstract
The utility model relates to an improvement of the drive housing of a double screw extruder. The upper side of the intermediate shaft of the drive housing is provided with two locating sleeves. The positions of the locating sleeves, and the extruder has two rotary directions. The back end of an output shaft is provided with an end cap. The end surface of the end cap is engaged with the contact surfaces of the outer circles of corresponding a plurality of cylindrical roller bearings which are arranged in a radial way, which causes the line speed of each point of the contact surface between the bearings and the end cap to be consistent, the wear to be reduced, and the service life of the bearings to be extended. The utility model has the advantages of simple structure, compact structure, stable operation, and range of use amplification for the extruder.
Description
The utility model is the improvement to the double screw extruder transmission case.
At present, the parallel double-screw extruder of domestic production and use, owing to be subjected to the restriction of two screw rods centre-to-centre spacing, make the thrust bearing quick abrasion of output shaft in the transmission case, thrust power is little, life-span is short, influence is produced, and various transmission cases only can be suitable for a kind of direction of rotation simultaneously, and the range of application of extruder is restricted, Chinese patent 90214643.2 super high bearing capacity ability screw-type extruders, though changed the arrangement of thrust bearing, prolonged the service life of bearing, linear velocity is inconsistent on the bearing contact-making surface, it is inconsistent to wear and tear, and is not easy to after the wearing and tearing adjust.
State weak point for fear of one, the purpose of this utility model is to provide a kind of transmission case that is used for double screw extruder, thrust power by radial arrangement two groups of two output shaft rear ends entad cylinder roller bearing bear, make thrust bearing each point linear velocity unanimity, prolong bearing service life; By increase by two positioning sleeves at jackshaft, change the positioning sleeve position, realize that two screw rods has two kinds of direction of rotation, promptly in the same way or incorgruous rotation, enlarge the scope of application of extruder.
In order to achieve the above object, the utility model has adopted following technical measures.
The transmission case of double screw extruder is made up of casing, output shaft, power shaft, intermediate propeller shaft, travelling gear.Institute's difference is the positioning sleeve that increases by two different thickness on jackshaft; In the supporting base at two output shaft rear portions, be provided with the entad cylinder roller bearing of two groups of arranged radiallys, end cap is equipped with in every output shaft rear end, and its end surface shape and pairing one group of bearing top circle forming surface match.
Another difference of the utility model is between the end cap of output shaft rear end and the output shaft adjustment pad to be housed, and end cap is fixed on the output shaft through screw.End cap can be along the output shaft move left and right.
In order to further specify characteristics of the present utility model, the embodiment below in conjunction with shown in the accompanying drawing 1 to 3 is described in detail.
