Abstract
The utility model discloses a shaft seal device for a gearbox of a pressing machine, and relates to an improvement of the shaft seal technology for the gearbox. The shaft seal device comprises a box body, a shaft, a gland, a bearing and a seal ring, wherein, a mesopore is formed on the gland; the shaft is connected with the box body through the bearing; the gland is fixedly connected with the outer part of the box body; the shaft extends out of the box body through the mesopore formed on the gland; the seal ring is arranged between the gland and the shaft; a stepped ring groove is formed on the outward mesopore edge of the mesopore formed on the gland; and the seal ring is arranged in the stepped ring groove. In the shaft seal device, the seal ring is arranged outside the gland, so that the seal ring is prevented from being impacted by pressure oil directly. An annular platform is arranged outside the mesopore edge of the mesopore on the inner side of the gland; an annular cavity chamber is formed on the inner end surface of the gland between the annular platform and a positioning annular platform; the pressure oil impacted from the bearing enters the cavity chamber directly; the cross section size of the cavity chamber is far greater than the size of a gap formed between the end surface of the annular platform and the end surface of an inner ring of the bearing, so that the pressure oil moves more along the annular cavity chamber, the oil pressure between the mesopore formed on the gland and the shaft is reduced, and the leakage is greatly reduced further.
Description
Technical field
The utility model relates to the press machine gear-box, relates in particular to the improvement to the gearbox shaft sealing technique.
Background technique
TC backbone sealing ring on the existing press machine gear shaft gland is built-in, and promptly the TC backbone sealing ring when gear shaft rotation drives the rolling bearing rotation, has pressure ground from the side spray to TC backbone sealing ring gear oil as oil pump in the inboard of gland seam.One, can cause the aging of sealing circle; Two, there is the oil pole of pressure easily to leak from axial clearance; Thereby cause and seal insecure situation herein.
Summary of the invention
The utility model is at above problem, provides a kind of pressure oil of avoiding directly to spray to matching gap between axle and gland, reduces the shaft sealer of the press machine gear-box of the local directly carrying of seal ring oil pressure simultaneously.
The technical solution of the utility model is: the gland, bearing and the seal ring that comprise casing, axle, band mesopore, described axle links to each other by bearing with casing, gland is fixedly connected on the casing outside, axle stretches out casing by the mesopore of gland, described seal ring is located between gland and the axle, the peritreme of described gland mesopore towards the outside is provided with a circle stepped slot, and described seal ring is located in the described stepped slot.
Described gland is provided with the positioning ring platform that a circle is used for the positioning bearing outer ring towards the end face of casing, and described gland mesopore is provided with the ring platform that a circle protrudes in the gland end face outside the peritreme of inside; The height of described ring platform is lower than the height of described positioning ring platform, and the external diameter of described ring platform is less than the external diameter of described bearing inner race.
The utility model has at first changed the state of the art of seal ring (TC skeleton) setting in the past with the gland inboard, and it is arranged on the outside of gland, has avoided the impact of the direct face bearing capacity of seal ring oil effectively.Outside the peritreme of the inboard mesopore of gland, be provided with the outstanding ring platform of a circle, like this, at the chamber that has formed an annular on the gland interior edge face between ring platform and the positioning ring platform, impacting the pressure oil that comes out from bearing directly enters in this chamber, because the sectional dimension of this chamber is far longer than the end face of ring platform and the gap size between the bearing inner race end face, pressure oil has reduced the oil pressure between gland mesopore and the axle more along the annular cavity operation, thereby greatly reduces the situation of leakage.
Description of drawings
Fig. 1 is a structural representation of the present utility model
1 is axle among the figure, the 2nd, and gear oil, the 3rd, annular cavity, the 4th, gland, the 5th, seal ring, the 6th, ring platform, the 7th, positioning ring platform.
Embodiment
The utility model as shown in Figure 1, the gland 4, bearing and the seal ring 5 that comprise casing, axle 1, band mesopore, described axle 1 links to each other by bearing with casing, gland 4 is fixedly connected on the casing outside, axle 1 mesopore by gland 4 stretches out casing, described seal ring 5 is located between gland 4 and the axle 1, and the peritreme of described gland 4 mesopores towards the outside is provided with a circle stepped slot, and described seal ring 5 is located in the described stepped slot.
Described gland 4 is provided with the positioning ring platform 7 that a circle is used for the positioning bearing outer ring towards the end face of casing, and described gland 4 mesopores are provided with the ring platform 6 that a circle protrudes in the gland end face outside the peritreme of inside; The height of described ring platform 6 is lower than the height of described positioning ring platform 7, and the external diameter of described ring platform 6 is less than the external diameter of described bearing inner race.
Working principle of the present utility model is: the seal ring 5 of TC skeleton is arranged at the outside of gland 4 seams, the mesopore of gland 4 seams and gear shaft 1 Spielpassung, when gear shaft 1 rotation drives the rolling bearing rotation, gear oil 2 pressure is arranged is sprayed in the annular cavity 3 of gland 4 inboards as oil pump, like this, gear oil 2 is no wiper seal with TC backbone sealing ring 5, greatly reduces the probability of leakage of oil.
