Abstract
The utility model relates to a sealing structure, in particular to a sealing structure which is applied to vertical lathe feeding box output shaft, and belongs to the technical field of sealing. The sealing structure comprises a feeding box body, the output shaft and a spline sleeve arranged at the end of the output shaft. The feeding box body is provided with a through hole, the output shaft is arranged in the feeding box body through the through hole, a spacer bush is arranged on the output shaft in a sleeved mode, the left end of the spacer bush abuts against the step face of the output shaft, and the spacer bush is in clearance fit with the output shaft. A framework oil seal is arranged at the gap between a shaft hole of the feeding box body and the spline sleeve, and therefore leakage of lubrication oil can be effectively avoided.
Description
Technical field
The utility model relates to a kind of sealing configuration, and specifically a kind of sealing configuration that is applicable to vertical car feed box output shaft place, belongs to technical field of sealing technology.
Background technique
In vertical lathe, feed box is mainly used for providing motion and power to lathe, and feed box mainly by input and output shaft, gear and bearing move, these component be all need lubricated, this just need to use lubricant oil, and because feed box itself has not been hermetic, therefore these lubricant oil will produce leakage.In view of the problem of above-mentioned existence, in the urgent need to developing a kind of sealing configuration of novel feed box output shaft place.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, ingenious, rational sealing configuration is provided, and this structure can effectively solve the problem of existing feed box oil leakage.
The technological scheme providing according to the utility model, the sealing configuration at a kind of feed box output shaft place, comprises feed box casing, output shaft and is arranged on the spline housing of output shaft end; On feed box casing, offer through hole, output shaft is installed in feed box casing by through hole, and spacer is sleeved on output shaft, and the left end of spacer withstands on the step surface of output shaft; Described spacer and output shaft are Spielpassung;
Deep groove ball bearing is installed on output shaft, and the left side of deep groove ball bearing withstands on the right side of spacer; The right-hand member of deep groove ball bearing is provided with spline housing, and described spline housing is installed on spline position corresponding on output shaft; The left side of described spline housing withstands on the right side of deep groove ball bearing, and by Cock screw, spline housing is fixed on output shaft; Gap location between described through hole right side and spline housing is installed an outside framework oil seal.
The aperture of the through hole on the external diameter of described outside framework oil seal and feed box casing adopts interference fit, and the internal diameter of outside framework oil seal and spline housing adopt interference fit.
The internal diameter of described deep groove ball bearing with output shaft on the diameter of axle adopt be the transition fit of unit bore system; The interference fit that through hole on the external diameter of described deep groove ball bearing and feed box casing is unit shaft system.
Described Cock screw is all fixed spline housing with respect to the position, axial and circumferential place of output shaft.
Described deep groove ball bearing makes the axial restraint of deep groove ball bearing at output shaft by the spacer on the left side and the spline housing on the right side.
The beneficial effects of the utility model: the utility model adopts the gap location between axis hole and the spline housing of feeding casing that one outside framework oil seal is installed, and can effectively prevent the leakage of lubricant oil.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1, feed box casing, 2, outside framework oil seal, 3, spline housing, 4, Cock screw, 5, output shaft, 6, spacer, 7, deep groove ball bearing, 8, through hole.
Embodiment
As shown in Figure 1: the sealing configuration at a kind of feed box output shaft of the utility model place, comprises feed box casing 1, output shaft 5 and be arranged on the spline housing 3 of output shaft 5 ends, and be arranged on the outside framework oil seal 2 on spline housing 3.
On feeding casing 1, offer the through hole 8 that output shaft is installed, output shaft 5 is arranged in the through hole 8 in feed box casing 1, then spacer 6 is loaded into from the right-hand member cover of output shaft 5, the left end of spacer 6 withstands on the step surface of output shaft 5.Wherein spacer 6 and output shaft 5 are Spielpassung.
Next deep groove ball bearing 7 is installed, the internal diameter of deep groove ball bearing 7 with output shaft 5 on the diameter of axle adopt be the transition fit of unit bore system, the interference fit that the output shaft hole on the external diameter of deep groove ball bearing 7 and casing 1 is unit shaft system.
The left side of deep groove ball bearing 7 withstands on the right side of spacer 6, and then spline housing 3 is installed.Described spline housing 3 is arranged on spline position corresponding on output shaft 5, the left side of spline housing 3 withstands on the right side of deep groove ball bearing 7, then with Cock screw 4, spline housing is fixed on output shaft 5, so the axial and circumferential of spline housing 3 on output shaft 5 have just been fixed.
Meanwhile, deep groove ball bearing 7 makes deep groove ball bearing 7 axially also having fixed on output shaft 5 by the spacer 6 on the left side and the spline housing 3 on the right side
As further improvement of the utility model, described through hole 8 on feed box casing 1 is installed an outside framework oil seal 2 near the gap location between right side place and spline housing 3, what the aperture of the output shaft hole on the external diameter of outside framework oil seal 2 and casing 1 adopted is interference fit, and what the internal diameter of outside framework oil seal 2 and spline housing 3 adopted is interference fit.
Compared with prior art, advantage is the utility model: the utility model adopts the gap location between axis hole and the spline housing 3 of feeding casing 1 that one outside framework oil seal 2 is installed, and can effectively prevent the leakage of lubricant oil.
