Abstract
The utility model discloses a gear box for single screw extruder, including box, two pairs of helical gears, bearing, end cover, input shaft, jackshaft and output shafts, output shaft one end is equipped with and is used for the splined hole be connected with the extruder screw rod, be equipped with out the shaft hole respectively on the end cover of input shaft and output shaft department, go out to be equipped with the double oil seal between shaft hole and input shaft and the output shaft respectively, being equipped with the hole that lies in between bearing and the end cover in the dead eye of output shaft and jackshaft one end respectively and using circlip, the hole is equipped with the holding ring between with circlip and bearing, is equipped with the holding ring that lies in between bearing and the end cover in the dead eye of input shaft one end. The utility model discloses play axle punishment at input shaft and output shaft do not is equipped with the double oil seal, therefore is difficult for the oil impregnate, one end at input shaft, jackshaft and output shaft sets up the holding ring, can improve the assembly precision of this gear box.
Description
Technical field
The utility model relates to a kind of gear-box for single screw extrusion machine.
Background technique
Current domestic single-screw extruder gearbox major part still adopts the beginning of the eighties in last century from the external design production technology introduced, because the conditions of manufacture of Mechanical Industry of China at that time limited, there is the easy oil impregnate of axial plane and the not high defect of assembly precision in single-screw extruder gearbox.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of not easily oil impregnate and the high gear-box for single screw extrusion machine of assembly precision.
The utility model solves the technological scheme that its technical problem adopts: a kind of gear-box for single screw extrusion machine, comprise casing, two pairs of helical gears, bearing, end cap, input shaft, jack shaft and output shafts, output shaft one end is provided with the splined hole for being connected with extruder screw, the end cap at described input shaft and output shaft shaft place is respectively equipped with shaft outlet hole, shaft outlet hole and be respectively equipped with dual-oil seal between input shaft and output shaft; Be respectively equipped with the circlip for hole between bearing and end cap in the bearing hole of output shaft and jack shaft one end, between circlip for hole and bearing, be provided with adjustment ring, in the bearing hole of input shaft one end, be provided with the adjustment ring between bearing and end cap.
Described oil sealing is dual-lip framework oil seal.
The beneficial effects of the utility model are: the utility model is respectively equipped with dual-oil seal at the shaft place of input shaft and output shaft, thus not easily oil impregnate; Adjustment ring is set in one end of input shaft, jack shaft and output shaft, the assembly precision of this gear-box can be improved.
