Description
Technical field
The present invention relates to a kind of sealing configuration, specifically a kind of sealing configuration being applicable to vertical car feed box output shaft place, belongs to technical field of sealing technology.
Background technique
In vertical lathe, feed box to be mainly used for providing motion and power to lathe, and feed box is mainly moved by input and output shaft, gear and bearing, these component be all need lubrication, this just needs to use lubricant oil, and due to feed box itself be not hermetic, therefore these lubricant oil will produce leakage.In view of above-mentioned Problems existing, in the urgent need to developing a kind of sealing configuration of novel feed box output shaft place.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, ingenious, rational sealing configuration, this structure effectively can solve the problem of existing feed box oil leakage.
According to technological scheme provided by the invention, a kind of sealing configuration of feed box output shaft place, comprises feed box casing, output shaft and is arranged on the spline housing of output shaft end; Feed box casing offers through hole, and 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 is fixed on output shaft by Cock screw by spline housing; Gap location on the right side of described through hole and between spline housing installs 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 is the transition fit of unit bore system with what adopt with the diameter of axle on output shaft; Through hole on the external diameter of described deep groove ball bearing and feed box casing is the interference fit of unit shaft system.
The axial and circumferential place position of spline housing relative to output shaft is all fixed by described Cock screw.
Described deep groove ball bearing makes deep groove ball bearing at the axial restraint of output shaft by the spacer on the left side and the spline housing on the right side.
Beneficial effect of the present invention: the present invention adopts the gap location between the axis hole and spline housing of feeding casing to install an outside framework oil seal, effectively can prevent the leakage of lubricant oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 present invention place, comprise feed box casing 1, output shaft 5 and be arranged on the spline housing 3 of output shaft 5 end, and be arranged on the outside framework oil seal 2 on spline housing 3.
Feeding casing 1 offers the through hole 8 installing output shaft, and be arranged on by output shaft 5 in the through hole 8 in feed box casing 1, be then loaded into by the right-hand member cover of spacer 6 from 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.
Following installation deep groove ball bearing 7, the internal diameter of deep groove ball bearing 7 is the transition fit of unit bore system with what adopt with the diameter of axle on output shaft 5, and the output shaft hole on the external diameter of deep groove ball bearing 7 and casing 1 is the interference fit of unit shaft system.
The left side of deep groove ball bearing 7 withstands on the right side of spacer 6, then installs spline housing 3.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 be fixed on output shaft 5 with Cock screw 4 by spline housing, so the axial and circumferential of spline housing 3 on output shaft 5 have just been fixed.
Meanwhile, deep groove ball bearing 7 makes the axis of deep groove ball bearing 7 on output shaft 5 also fix by the spacer 6 on the left side and the spline housing 3 on the right side
As a further improvement on the present invention, described through hole 8 on feed box casing 1 installs 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 in the present invention: the present invention adopts the gap location between the axis hole and spline housing 3 of feeding casing 1 to install an outside framework oil seal 2, effectively can prevent the leakage of lubricant oil.
