Abstract
The utility model discloses a split gear sleeve which is designed and machined in a split mode. The split gear sleeve is composed of a cylindrical gear grinding outer gear, an inner gear spline, a connection part and a pressing ring. The cylindrical gear grinding outer gear and the inner gear spline are not integrated but connected through the connection part. The pressing ring is arranged on the connection part. The cylindrical gear grinding outer gear is easily ground. After the cylindrical gear grinding outer gear is carburized and quenched and undergoes gear grinding, a face of the cylindrical gear grinding outer gear is high in rigidity, precision, bearing capability, and transmission efficiency, little in mechanical energy loss and long in service life. The inner gear spline and the cylindrical gear grinding outer gear transmit torque through match of the gears and are positioned by the pressing ring. Power of a reduction box of an extruder is transmitted to the cylindrical gear grinding outer gear of a gear sleeve through the inner gear spline and then transmitted to a feeding side pressing roll of the extruder. The split gear sleeve can not replace an integrated gear sleeve of an existing extruder, wherein the integrated gear sleeve can not perform carburization, quenching and gear grinding. Bearing capacity of the gear sleeve of the extruder is greatly improved and service life of the gear sleeve of the extruder is greatly prolonged.
Description
Technical field
The utility model relates to a kind of extruder split geared sleeve of high precision and long service life of flank of tooth roll flute, be used for rubber Cold-feed extruder by the speed reducer lower velocity shaft to other press roll gear transmitting power, realize that efficient engagement forces to feed glue.Split geared sleeve tooth face hardness height behind carburizing and quenching and roll flute, the precision height, the bearing capacity height, the transmission efficiency height, the mechanical energy loss is few, long service life.
Background technique
The key of geared sleeve is the tooth face hardness and the precision of gear, and gear can improve surface hardness and bearing capacity through carburizing and quenching, but the gear behind the carburizing and quenching needs roll flute could guarantee highi degree of accuracy.The geared sleeve of present common usefulness is an overall structure, and its flank of tooth or do not do carburizing and quenching to handle and cause bearing capacity low is easy to wear, does perhaps that carburizing and quenching is handled the back because the restriction of structure, and the flank of tooth can not roll flute, causes the flank of tooth coarse, and easy to wear, transmission efficiency is low.If will be on monolithic construction roll flute, then need to increase the length of geared sleeve, and geared sleeve is a cantilever structure, increases length and will increase jib-length, can weaken the bearing capacity of geared sleeve, thereby reduce working life; Simultaneously, can't solve in a large number wear problem at the geared sleeve of the extruder of usefulness if the whole length that increases geared sleeve then can't be exchanged with the geared sleeve of existing extruder.
Summary of the invention
The purpose of this utility model provides a kind of split geared sleeve of high precision and long service life of flank of tooth roll flute.
The utility model is achieved in that the split geared sleeve adopts split design and processing, is made up of cylinder roll flute external gear, internal gear spline, link and pressure ring; Cylinder roll flute external gear and internal gear spline are not an integral body, but connect by link, and pressure ring is arranged on the link.
The split geared sleeve is used for the transmission of power of extruder speed reducer is given the other press roll gear of extruder, realizes that efficiently glue is fed in the engagement pressure; Cylinder roll flute external gear is easy to roll flute, the cylinder roll flute external gear teeth surface hardness height behind carburizing and quenching processing and roll flute, and the precision height, the bearing capacity height, the transmission efficiency height, the mechanical energy loss is few, long service life; The internal gear spline cooperates transmitting torque with cylinder roll flute external gear by the gear teeth and is located by pressure ring; The power of extruder speed reducer is delivered to the cylinder roll flute external gear of geared sleeve through the internal gear spline, passes to the other pressure roller of feeding of extruder again.
Geared sleeve of the present utility model can replace the integral gear cover that can't carry out carburizing and quenching and roll flute of present extruder, the bearing capacity and the working life of significantly improving the extruder geared sleeve.
Description of drawings
Fig. 1 is common overall gear cover.
Fig. 2 is the split geared sleeve of the high precision and long service life of flank of tooth roll flute of the present invention.
Mark among the figure: 1-cylinder roll flute external gear, 2-internal gear spline, 3-pressure ring, 4-link.
Embodiment
Embodiment:
As shown in Figure 2, the split geared sleeve adopts split design and processing, is made up of cylinder roll flute external gear 1, internal gear spline 2, link 4 and pressure ring 3; Cylinder roll flute external gear 1 is not an integral body with internal gear spline 2, but connects by link 4, and pressure ring 3 is arranged on the link.
Cylinder roll flute external gear 1 material is 20CrMnTi or similar alloyed steel, roll flute again behind the flank of tooth carburizing and quenching.Internal gear spline 2 adopts 40Cr or similar alloyed steel, quenching with Subsequent tempering.This split geared sleeve is applied to 200 extruders and 150 extruders, uses after 2 years, checks that its flank of tooth is smooth smooth, no noticeable wear vestige.Check tenor in the gear lubricant, use the tenor few 80% of common overall gear cover.The gear wear that this split of use geared sleeve is described is few, and working life is longer than common overall gear cover.
Above-mentioned case study on implementation is a kind of practical use of the present utility model, is not to qualification of the present utility model.The utility model is applicable to the cold extruder of feeding of the rubber of all specifications.
