Abstract
The utility model provides a bearing box for a pump transmission set, comprising a four-point contact ball bearing, a single-row cylindrical roller bearing, a main shaft and a bearing box, wherein the inner ring of the single-row cylindrical roller bearing is sheathed on the main shaft, and fixedly connected with the main shaft through a first adjustment nut; a single-row cylindrical roller is installed in a raceway formed by the inner ring and the outer ring of the single-row cylindrical roller bearing; the four-point contact ball bearing is installed at the right side of the single-row cylindrical roller bearing; C-shaped grooves are respectively arranged on the end faces of two outer rings at the location of butt-joint between the two bearings; the inner ring of the four-point contact ball bearing is sheathed on the main shaft, and fixedly connected with the main shaft through a second adjustment nut; a ball roller is installed in the raceway formed by the inner ring and the outer ring of the four-point contact ball bearing; the single-row cylindrical roller bearing and the four-point contact ball bearing are integrally installed in the bearing box; and a bearing gland is buckled on the bearing box. Through the structural modification of the bearing box for the pump transmission set, the properties of the bearing is greatly improved, the service life is prolonged, the failure rate is decreased, and the whole performance is promoted two times.
Description
Technical field
The utility model belongs to field of bearings, and particularly a kind of slurry pump transmission group is used bearing housing.
Background technique
Last century, the eighties was introduced mud industrial pump model machine and technology from Canada, and after the bearing production domesticization, bearing life does not reach machine life requirement (1 year quality guarantee period) over more than 20 year, and individual cases damage frequent.Especially frequent at 250PN type slurry pump transmission group with the bearing housing fault.
Transmission group is carried out exhaustive analysis with bearing housing runnability and damage of bearings reason, reach a conclusion: reduce transmission group and use the bearing housing rate of fault, must improve the bearing capacity of bearing; Limited because of the bearing housing space, can only in original space, adjust bearing housing structure, with the usage requirement that conforms; In addition, traditional structure is owing to have spacer ring, and it is many that shaft strength lost efficacy; Receive the influence that spacer ring spare quality is aging and wear and tear; Spacer ring spare very easily damages, and influences the reliability of bearing, and then influences bearing life.
The model utility content
The purpose of the utility model provides a kind of pump drive group and uses bearing housing, and the bearing life of this bearing housing is long, and performance is good, and structure is special, and end face has C type groove, and bearing joint two cycle surfaces strengthen the R dihedral and become oil groove.
The technological scheme that adopts is:
A kind of pump drive group is used bearing housing, comprises four-point contact ball, single row roller bearing, main shaft and bearing housing;
The inner ring of single row roller bearing is sleeved on the main shaft, is fixedly connected with main shaft through the first adjustment nut, and single-row cylinder roller is installed in the raceway of inner ring and outer ring formation of single row roller bearing; Right side at single row roller bearing is equiped with four-point contact ball; Offer C type groove respectively at two bearings joint two cycle surfaces, strengthen the R angle, substituted the oil groove oilhole of original spacer ring; Guarantee the lubricating function of original structure; The inner ring of four-point contact ball is sleeved on the main shaft, is fixedly connected with main shaft through the second adjustment nut, and the ball roller is installed in the raceway of inner ring and outer ring formation of four-point contact ball; Single row roller bearing and four-point contact ball integral installation are in bearing housing, and bearing gland be located on the bearing housing.
The advantage of the utility model is:
The utility model increases substantially bearing load carrying capacity through structure of modification, increases the service life, and reduces the generation of rate of fault; Structurally removed spacer ring, eliminated the unfavorable factor of spacer ring spare, milled out C type groove respectively at two bearings joint two cycle surfaces; Strengthen the R angle; Substitute the oil groove oilhole of original spacer ring, guaranteed the lubricating function of original structure, made this structural entity bearing capacity promote twice.
