Abstract
The utility model discloses a metal solid retainer for thrust cylinder roller bearing for horizontal shaft, which comprises a retainer seat 4 and a retainer cover 5, wherein a plurality of arc pocket holes 9 formed by radial drilling and cutting are evenly distributed on the retainer seat 4, the height of the retainer seat 4 is equal to that of the retainer cover 5, the retainer seat 4 and a horizontal shaft 7 adopt clearance fit, namely the horizontal shaft 7 is used for guiding the retainer, the inner diameter of the retainer is provided with a lubricating oil groove arranged along the circumference for reducing the contacting area between the inner diameter of the retainer and the horizontal shaft 7, and the outer diameter size of the retainer cover 5 is smaller than that of a shaft ring 1, which prevents friction and collision interference between the retainer and a shell. The retainer of the utility model has the characteristics of high precision, low vibrating noise, stable operating, excellent lubricating effect and long service life.
Description
Technical field
The utility model belongs to a kind of retainer, relates generally to a kind of horizontal axis with the cylindrical roller thrust bearing metal solid holding frame.
Background technique
Cylindrical roller thrust bearing is made up of blowout patche, seat ring, roller, retainer, can bear bigger pure axial force.Usually cylindrical roller thrust bearing becomes horizontal positioned, and the axle that promptly is mated is a vertical direction.Large-scale cylindrical roller thrust bearing retainer is generally by keeping stand and retainer lid to form, and is evenly equipped with a plurality of arc pocket holes that formed by drilling radially on it.Keep a side of stand that a step is generally arranged, be used for retainer is supported on the raceway of seat ring, can uniform several oil grooves on the step, keep connecting with straight pin between stand and the retainer lid, and the locking of cutter seal.See accompanying drawing 1.
On large-size horizontal precision machine tool main shaft, cylindrical roller thrust bearing then is vertically to install, and promptly machine tool chief axis is a level.When Bearing Installation is on horizontal axis, because the gap between retainer and the axle is bigger, roller and retainer will cause the rotating center instability owing to gravity sag, thereby precision reduces; If this moment retainer external diameter again near the external diameter of seat ring, then will retainer take place during bearing operation and housing is collided, cause the damage of bearing and lathe housing, consequence is hardly imaginable.Therefore need improve design to the structure and the guide clearance of retainer, avoid because the running accuracy that the radial-play of roller and retainer causes reduces and with the interference and collision of component on every side.
Summary of the invention
The purpose of this utility model provides a kind of horizontal axis with the cylindrical roller thrust bearing metal solid holding frame, makes that it has the precision height, vibrating noise is low, running is steady, the characteristics of high lubricating effect, long service life.
The purpose of this utility model can adopt following technological scheme to realize: a kind of horizontal axis is with the cylindrical roller thrust bearing metal solid holding frame, mainly by keeping stand and retainer lid to form, keep being evenly equipped with on the stand a plurality of arc pocket holes that form by drilling radially, wherein, the height of described maintenance stand equates with the retainer lid, keep adopting Spielpassung between stand and the horizontal axis, promptly utilize horizontal axis to guide retainer, and on the internal diameter of retainer, have an oil groove that sets along circumference, reduce the area of contact between retainer internal diameter and the horizontal axis; The outside dimension of retainer lid is less than the outside dimension of blowout patche, avoids that retainer and housing rub, interference and collision.

Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
Shown in accompanying drawing 4,5,6, and with reference to Fig. 2,3, the utility model retainer is by keeping stand 4 and retainer lid 5 to form, is evenly equipped with a plurality of arc pocket holes 9 that formed by drilling radially on the maintenance stand 4.Keep connecting with straight pin 6 between stand 4 and the retainer lid 5, and in the cutter seal locking of place, pin aperture.Keep stand 4 to equate, do not need a side band step with the height of retainer lid 5.Keep adopting Spielpassung between stand 4 and the horizontal axis 7, promptly utilize horizontal axis 7 to guide retainer, at oil groove that 0.5～1mm is dark of the internal diameter upper edge of retainer circumference processing, to reduce the area of contact between retainer internal diameter and the horizontal axis 7, during installation, oiling on horizontal axis 7 is avoided producing frictional heating between retainer internal diameter and the horizontal axis 7.The outside dimension of retainer lid 5 is less than the outside dimension of blowout patche 1, avoids that retainer and housing rub, interference and collision.
