Abstract
The utility model relates to a low speed high-torque gear case for an extruder. The low speed high-torque gear case for the extruder comprises a body, the body is provided with an input shaft, a first middle shaft, a second middle shaft and two transition shafts, the body is a split upper and lower case component with a mounting hole and is formed in a split casting mode, an input gear wheel is arranged on the input shaft, a first middle gear wheel and a second middle gear wheel are arranged on the first middle shaft, a third middle gear wheel is arranged on the second middle shaft, a fourth middle gear wheel and a fifth middle gear wheel are arranged on the transition shafts, and the input gear wheel is meshed with the second middle gear wheel through the first middle gear wheel. By means of the low speed high-torque gear case for the extruder, requirements of present double-screw extruders for high torque, high rotating speed and high reliability of the gear case can be met, the carrying capacity is high, and good shock resistance and carrying capacity are achieved.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of low speed high torque gear box for extruder.
Background technique
Extruder has excellent Combination and good adaptability, its manufacturing efficiency that improves extruder, realize equipment multifunction, improve to compare with common extruder aspect quality of product and be significantly improved.The devolatilization that is widely used in filling, blend, modification, enhancing, chlorinated polypropylene and the super absorbent resin of rubber and plastic and engineering resin is processed; Extruding of degradable masterbatch, polyamide polycondensation, polyurethane addition polymerization; The preparation of the granulation of carbon dust, magnetic, insulating material for cable, protective cover material, low smoke and low halogen type PVC CABLE MATERIALS and various crosslinked with silicane material etc.Along with market requires to improve constantly to the manufacturing efficiency of parallel double-screw extruder, as the gear-box of the motivation transfer motion part of parallel double-screw extruder also more and more to high moment of torsion, high rotating speed, high reliability development.The parallel double-screw extruder gear-box major part foreign technology for introducing the nineties still in the market, difference due to material and production technology, it is low that domestic parallel double-screw extruder gear-box ubiquity moment of torsion, poor reliability, noise is large, easy seepage wet goods defective limits due to the centre distance of screw rod that double screw extruder is joined and small-sized simultaneously, so the bearing capacity of the situation raising gear-box that gear-box must limit in output shaft AB centre distance.And wherein B shaftgear acceptor center can not be too large apart from limiting, and is the weakest link of bearing capacity, can't satisfy the requirement of the high rotating speed of the high moment of torsion of parallel double-screw extruder and high reliability.
The model utility content
The purpose of this utility model is to solve the problem of above-mentioned existence, and a kind of low speed high torque gear box that is used for extruder smooth and easy, that noise is low, vibration is little, moment of torsion is high that meshes is provided.
The technological scheme that realizes the utility model purpose is: a kind of low speed high torque gear box for extruder, has body, body is provided with input shaft, the first jack shaft, the second jack shaft, two transition axises, body is the upper nowel split part with mounting hole that split casting forms, input shaft is provided with input gear, the first jack shaft is provided with the first center tooth and the second center tooth, the second jack shaft is provided with the 3rd center tooth, transition axis is provided with the 4th center tooth and the 5th center tooth, and input gear is connected with a joggle by the first center tooth and the second center tooth.
Further, two transition axises that are used for the low speed high torque gear box of extruder be arranged in parallel, and two the 6th center tooth mesh with the 5th center tooth simultaneously, two the 7th center tooth whiles and the engagement of the second output gear.
The utlity model has following characteristics: body of the present utility model is upper nowel Split type structure, has good anti-seismic performance and load-carrying properties.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
