Abstract
The utility model discloses a planet speed reducer for a horizontal tubular submersible pump. The planet speed reducer comprises a machine body, an inner gear ring and a sun wheel which are arranged in the machine body, a planet wheel which is arranged between the inner gear ring and the sun wheel and respectively meshed with the inner gear ring and the sun wheel, a planet carrier which is used for fixing the planet wheel, an input shaft which is sleeved on the sun wheel, an output shaft which is connected to the planet carrier, and a ball head which is arranged in the axial installation hole of the output shaft and used for axially positioning the sun wheel. A spring is arranged at the front end of the sun wheel and positioned in the spline sleeve of the input shaft, and a bearing is arranged outside the ball head and positioned in the axial installation hole of the output shaft. The planet speed reducer for the horizontal tubular submersible pump has a simple structure and is low in manufacturing cost, the preloaded axial force of the sun wheel is ensured, friction caused by relative slide between the sun wheel and the ball head is avoided, and the service life of the speed reducer is prolonged.
Description
Technical field
The utility model relates to the planetary reducer field, specifically is that a kind of horizontal through-flow submersible pump is used planetary reducer.
Background technique
Horizontal through-flow submersible pump is used planetary reducer; Comprise pass through before having lid and back pass through the body of lid, respectively be arranged at the body front-end and back-end forward flange and rear flange, be installed on ring gear and sun gear in the body, be arranged between ring gear and the sun gear and and the planet wheel that meshes respectively of ring gear and sun gear, be used to make planet wheel to be evenly arranged in the planet carrier on the circumference between ring gear and the sun gear, be set in input shaft on the sun gear, be connected in the output shaft on the planet carrier and be arranged in the axial mounting hole of output shaft and be used for bulb the sun gear axially locating; Input shaft and output shaft are the involute splines nested structure; Motor shaft is arranged in the spline housing of input shaft, and output shaft is connected with horizontal through-flow submersible pump.Because motor shaft is to be connected through input shaft with the sun gear of retarder, both connect for contact, and during the retarder running, sun gear is easy to take place axial float, influences the normal use of retarder.
The model utility content
The technical problem that the utility model will solve provides a kind of horizontal through-flow submersible pump and uses planetary reducer, solves the problem of existing horizontal through-flow submersible pump with planetary reducer operational effect difference.
The technological scheme of the utility model is:
Horizontal through-flow submersible pump is used planetary reducer; Comprise body, be installed on ring gear and sun gear in the body, be arranged between ring gear and the sun gear and and the planet wheel that meshes respectively of ring gear and sun gear, be used to make planet wheel to be evenly arranged in the planet carrier on the circumference between ring gear and the sun gear, be set in input shaft on the sun gear, be connected in the output shaft on the planet carrier and be arranged in the axial mounting hole of output shaft and be used for bulb the sun gear axially locating; Described input shaft and output shaft are the involute splines nested structure; Output shaft and planet carrier are integral structure, and the front end of described sun gear and the spline housing that is positioned at input shaft are provided with spring.
Outer and the axial mounting hole that be positioned at output shaft of described bulb is provided with bearing.
The front end of described sun gear and the spline housing that is positioned at input shaft are provided with position shelf, and described spring is arranged on the position shelf.
Outer and the axial mounting hole that be positioned at output shaft of described bulb is provided with angular contact bearing.
The advantage of the utility model:
(1), be provided with the position shelf that has spring at the front end of sun gear and the spline housing that is positioned at input shaft, through spring produce to sun gear add axial force in advance, avoid the axial float of sun gear;
(2), because the rotating speed of the rotating speed of bulb and planet carrier is identical, thereby promptly can produce speed discrepancy and produce relative movement and produce force of sliding friction with sun gear; After adding bearing, the frictional force between bulb and bearing is less than force of sliding friction, and bulb can rotate, like this sun gear not relatively bulb displacement is arranged, and the bulb that weares and teares.
