Embodiment Construction

[0014] The present invention will be further described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0015] Such as figure 1 As shown, a screw drive sleeve of a single-screw rubber extruder, the specific structure is: the screw 1 is installed in the feeding seat body 2, the inner involute spline at the rear of the drive sleeve 4 and the outer shaft of the output shaft 3 of the reduction box The involute splines are matched, the inner involute splines in the middle of the transmission sleeve 4 are matched with the outer involute splines in the tail journal of the screw 1, the outer involute gears in the front of the transmission sleeve 4 are matched with the feeding roller The gear 5 of 6 constitutes the feed roller gear pair.

[0016] Principle of the present invention is:

[0017] The output shaft 3 of the reduction box transmits the torque and rotational speed to the transmission sleeve 4 through the involute spline, and ...

Abstract

The invention belongs to the rubber machining mechanical equipment field and relates to a screw rod transmission sleeve for a single screw rod rubber extruder. An inner involute spline at the rear portion of the transmission sleeve is matched with an outer involute spline of an reduction box hollow output shaft; an inner involute spline in the middle of the transmission sleeve is matched with an outer involute spline of an screw rod tail portion shaft neck, an outer involute gear in the front of the transmission sleeve and a feeding roll gear form a feeding roll gear pair. The transmission sleeve can achieve a direct transmission on the screw rod and the feeding roll.

Description

Technical field: [0001] The invention relates to the field of rubber processing machinery and equipment, in particular to a screw drive sleeve of a single-screw rubber extruder. Background technique: [0002] Rubber single-screw rubber extruder (including hot feed and cold feed) is characterized by low speed and constant torque. Usually, a gear reducer is used to reduce the high speed of the motor to a low speed and increase the driving torque to meet the needs of the screw. The driving of the screw is realized by a certain form of connection between the tail of the screw and the hollow output shaft of the gear reducer (the main purpose of the hollow shaft is to cool the screw). [0003] In the early single-screw rubber extruders, the journal at the end of the screw is usually connected with (one or two 180° apart) flat keys or rectangular splines to cooperate with the hollow output shaft hole of the gearbox, and no transmission sleeve is designed. This design has its inhe...
