Abstract
The utility model discloses a gear case for a plastic extruding machine. The gear case is mainly composed of a case body component, an input shaft component, a middle shaft component and an output shaft component. An input shaft of the input shaft component is connected with external force, and input shaft teeth are meshed with a middle shaft gear sleeved with a middle shaft in a hot mode in the middle shaft component. Middle shaft teeth are meshed with an output shaft gear sleeved with an output shaft in a hot mode in the output shaft component. The output shaft is connected with the plastic extruding machine through a spline. The output shaft is supported on the case body component through a self-aligning roller bearing and a cylindrical roller bearing. Another thrust bearing is further arranged on a case body close to the cylindrical roller bearing and between the self-aligning roller bearing and the cylindrical roller bearing. The outer ring of the cylindrical roller bearing is arranged in an inner hole of an end cover of the thrust bearing, and an input shaft and the middle shaft are supported into the integral case body through tapered roller bearings which are arranged in a left-and-right mode respectively. The gear case for the plastic extruding machine can greatly shorten the axial distance of the gear case and can completely meet the use requirements of foreign customers, and the size of the whole gear case is small.
Description
Technical field
The utility model relates to the gear-box that a kind of extruder is used, be mainly used in the screw drive of domestic and international extruder industry, belong to industrial uni-drive gear box.
Background technique
The gear-box market capacity of extruder industry is larger both at home and abroad at present, the bearing arrangement form of domestic like product output shaft is generally a pair of selfaligning bearing and adds a thrust-bearing, thrust-bearing can adopt this kind arrangement near output shaft end cap one side (as shown in Figure 2) in the not limited situation of installing space; But owing to the axial distance of existing gearbox output shaft makes the volume of whole gear-box larger greatly, thereby possibly can't satisfy the installation requirement of new customer equipment.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned existence, and a kind of that prior art is improved, axial distance weak point, compact structure, lightweight, volume is little, the extruder of reliable in function is used gear-box are provided, it can subrogate country outside the extruder gear-box of famous brand.
The purpose of this utility model is finished by following technical solution, it is mainly by box part, the input shaft parts, intermediate shaft part, output shaft assembly forms, the input shaft of input shaft parts links to each other with outer power, the countershaft-gear of hot jacket on jack shaft is meshed in input shaft tooth and the intermediate shaft part, the output shaft gear of hot jacket on output shaft is meshed in jack shaft tooth and the output shaft assembly, output shaft is connected with extruder by spline, it is characterized in that described output shaft is supported on the box part by selfaligning roller bearing and roller bearing, and between selfaligning roller bearing and roller bearing, also be furnished with another thrust-bearing near on the casing of roller bearing.
Roller bearing described in the utility model outer ring is installed in the endoporus of thrust-bearing end cap, it can greatly shorten gearbox shaft to size, make simultaneously splash lubrication more secure to thrust-bearing; Described input shaft and jack shaft respectively by about the tapered roller bearing arranged be supported in the casing of described integral form easy disassembly.
The utility model is respectively arranged with mounting hole and attachment face in four sides of casing, makes gear-box that multiple mounting modes can be arranged.
The utility model adopts thrust-bearing to be placed on middle arrangement, can greatly shorten the axial distance of gear-box, and whole gear-box volume is less, and installation dimension is little, satisfies external client's usage requirement fully.While also provides the model that can use for reference for the compact design of domestic gear-box.The utility model takes into full account design requirement when design, on four faces of side, mounting hole and attachment face have all been designed, make gear-box that multiple mounting modes can be arranged, also can change to pressure lubrication by splash lubrication easily simultaneously, satisfy the diversified demand of user.And under the prerequisite of quality assurance, there is price advantage than same kind of products at abroad, more is conducive to occupy the domestic and international market, enhance competitiveness, create profit.
Description of drawings
Fig. 1 is drive mechanism schematic representation of the present utility model.
Fig. 2 is the structural representation of existing conventional extruder gearbox output shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model is mainly by casing 1, input shaft parts 2, intermediate shaft part 3, output shaft assembly 4 forms, the input shaft of input shaft parts 2 links to each other with outer power, the countershaft-gear 6 of hot jacket on jack shaft is meshed in input shaft tooth 5 and the intermediate shaft part 3, the output shaft gear 8 of hot jacket on output shaft 9 is meshed in jack shaft tooth 7 and the output shaft assembly 4, output shaft 9 is connected with extruder by spline 10, described output shaft 9 is supported on the casing 1 by selfaligning roller bearing 11 and roller bearing 12, and between selfaligning roller bearing 11 and roller bearing 12, also be furnished with another thrust-bearing 13 near on the casing 1 of roller bearing.
Described roller bearing 12 outer rings are installed in the endoporus of thrust-bearing end cap; Described input shaft and jack shaft respectively by about the tapered roller bearing arranged be supported in the casing 1 of described integral form.
Be respectively arranged with mounting hole and attachment face on four sides of described casing 1.
Embodiment: the utility model mainly is comprised of box part 1, input shaft parts 2, intermediate shaft part 3, output shaft assembly 4.Power passes through the rotation of driven by motor input shaft, and input shaft tooth 5 and countershaft-gear 6 are meshed, and drives intermediate shaft part 3 and rotates, and jack shaft tooth 7 and output shaft gear 8 are meshed and drive output shaft assembly 4 rotations, and output shaft 9 is connected with extruder by spline 10.
Because housing is whole, consider the convenient and space layout of mounting or dismounting, input shaft parts 2 and intermediate shaft part 3 all adopt tapered roller bearing.
The utility model is by reasonable Arrangement, raising gear and the housing machining accuracy of gear tooth thickness attenuate (under the prerequisite of proof strength), thrust-bearing, and the methods such as the irregular design of gear have reduced bulk effectively.
