Description
Technical field
The utility model relates to speed reducer field, is specifically related to a kind of submersible pump special reduction gear.
Background technique
Submersible pump planetary reducer generally includes and is installed on ring gear in body and sun gear, to be arranged between ring gear and sun gear and the planet wheel engaged respectively with ring gear and sun gear, for making planet wheel be evenly arranged between ring gear and sun gear planet carrier, the input shaft be set on sun gear, the output shaft be connected on planet carrier circumferentially, motor shaft is arranged in the spline housing of input shaft, and output shaft is connected with submersible pump.Because motor shaft and the sun gear of retarder are connected by input shaft, both are contact connection, and during retarder running, sun gear is easy to axial float occurs, and affects the normal use of retarder.
Summary of the invention
The purpose of this utility model is to provide a kind of good sealing effect and can prevents sun gear from loosening a kind of submersible pump special reduction gear with play.
For reaching above object, the technological scheme that the utility model is taked is:
A kind of submersible pump special reduction gear, comprise motor, speed reducer and the pump housing, speed reducer is connected between motor and the pump housing, described speed reducer comprises casing, input shaft, output shaft and planetary gear speed reducing mechanism, described input shaft connects the output terminal of motor, output shaft connects the input end of the pump housing, described planetary gear speed reducing mechanism comprises sun gear, planet carrier, planet axis, ring gear and planet wheel, described sun gear is connected to one end of input shaft through connecting sleeve, the two ends of described planet carrier are supported in casing through bearing respectively, one end of planet carrier is socketed on the outside of connecting sleeve, the other end of planet carrier is connected with output shaft through screw thread, many planet axis are distributed in planet carrier, each planet axis is supported with planet wheel through plural bearing respectively, with between the bearing in root planet axis by bearing spacer interval, ring gear is socketed on the outside of planet carrier and is fixedly connected with casing through screw, and planet wheel engages with the internal tooth of sun gear and ring gear simultaneously.
Further, described input shaft is provided with oil sealing, oil sealing is arranged on input shaft and casing joint in casing.
Again further, be supported with ball top through bearing in described planet carrier, described ball apical axis is to the end pushed against in sun gear.
After taking above technological scheme, the beneficial effects of the utility model are:
In planet carrier, be provided with the ball top pushing against sun gear, ball apical axis is to pushing against sun gear, and what can prevent sun gear volume axial float from sun gear can be avoided to be connected with connecting sleeve on the one hand loosens simultaneously; Ball top can apply precompression to input shaft on the other hand, and the filler oil sealing on input shaft is sealed better; Through bearing spacer interval between the two bearings in planet axis, avoid bearing play in planet axis.
