Abstract
The invention discloses an embedded type end cover sealing structure which comprises a power output shaft and is characterized in that a bearing seat is arranged at one end of the power output shaft, and a bearing in contact with the power output shaft is arranged in the bearing seat. A sealing structure is arranged between the bearing seat and the power output shaft. An embedded end cover matched with the power output shaft is arranged in the bearing seat, and the sealing structure is arranged between the embedded end cover and the power output shaft. By means of the embedded type end cover sealing structure, an oil leakage condition is avoided effectively, and axial locating is achieved through the box body bearing seat, an embedded end cover stop opening and a power output shaft shoulder. In addition, the embedded type end cover sealing structure is simple and attractive in design, has a dual-sealing effect and effectively solves the problems of small space and oil leakage.
Description
Technical field
The present invention relates to a kind of embedded end bracket enclosed structure.
Background technique
Planetary speed reducer is a kind of broad-spectrum industrial products, its performance can compare favourably with other army's grade speed reducer product, the price that technical grade product is but arranged is mainly used in the swirl gear of tower crane, can be used as matching parts again and is used for industries such as lifting, excavation, transportation, building.
The end cap of using on the speed reducer all is the seam location at present, and bolt needs certain space to place and the stubborn bolt of spacing closing between end cap and the end cap.But smaller in some centre distance, when the space was smaller, if with the end cap of this structure, one was not have local auger shell keyhole, not handy bolt, and another is that the space is easy to leakage of oil for a short time, is speed reducer one big disadvantage.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned defective, and a kind of double seal effect of playing is provided, and has effectively solved the embedded end bracket enclosed structure of the little leakage of oil problem in space.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of embedded end bracket enclosed structure comprises pto, it is characterized in that: an end of described pto is provided with bearing support, is provided with the bearing that contacts with pto in the bearing support; Be provided with sealing configuration between described bearing support and the pto.
Be provided with the embedded end cap that is complementary with pto in the described bearing support, be provided with sealing configuration between embedded end cap and the pto.
Described sealing configuration comprises the seal ring that is arranged on the embedded end cap.
Described seal ring is O type circle.
Circular O type circle is made, is to described O type circle by rubber material.
Described sealing configuration comprises the Sealing that is arranged between embedded end cap and the pto.
Described Sealing is the oil sealing of static seal.
Described oil sealing is that rubber coats and fully with the two-lip seal of self-tightening spring.
Owing to adopted technique scheme, compared with prior art, embedded end cap of the present invention is contained in housing bearing seat inside, be fit to the space outerpace restriction, the less situation of bearing hole spacing is used, simultaneously, O type circle is installed on the embedded end cap, prevent that oil from spilling from the box body hole cylindrical, embedded end cap also and oil sealing is installed between the pto prevents that oil from spilling along axle.The present invention efficiently solves the leakage of oil situation, can not be coated with sealer sealing by end face as traditional end cap, when the bearing hole spacing hour, traditional end cap is little because of sealing area, very easily leakage of oil.Axially locating is to locate by housing bearing seat and embedded end cap seam, the pto shaft shoulder, and in addition, the present invention designs succinctly attractive in appearance, has the double seal effect, has effectively solved the little leakage of oil problem in space.
The invention will be further described below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Embodiment
Embodiment:
As shown in Figure 1, a kind of embedded end bracket enclosed structure comprises pto 6, and an end of described pto 6 is provided with bearing support 2, is provided with the bearing 3 that contacts with pto in the bearing support 2.Be provided with sealing configuration between bearing support 2 and the pto 6.
In the present embodiment, be provided with the embedded end cap 1 that is complementary with pto 6 in the described bearing support, be provided with sealing configuration between embedded end cap 1 and the pto 6.
Sealing configuration comprises the seal ring that is arranged on the embedded end cap 1, and seal ring is O type circle 4.In the present embodiment, circular O type circle is made, is to described O type circle 4 by rubber material.
In the present embodiment, described sealing configuration comprises the Sealing that is arranged between embedded end cap and the pto.Described Sealing is the oil sealing 5 of static seal.Consider practical effect, oil sealing 5 coats for rubber and fully with the two-lip seal of self-tightening spring.
Embedded end cap of the present invention is contained in housing bearing seat inside, be fit to the space outerpace restriction, the less situation of bearing hole spacing is used, simultaneously, O type circle is installed on the embedded end cap, prevent that oil from spilling from the box body hole cylindrical, embedded end cap also and oil sealing is installed between the pto prevents that oil from spilling along axle.The present invention efficiently solves the leakage of oil situation, can not be coated with sealer sealing by end face as traditional end cap, when the bearing hole spacing hour, traditional end cap is little because of sealing area, very easily leakage of oil.Axially locating is to locate by housing bearing seat and embedded end cap seam, the pto shaft shoulder, and in addition, the present invention designs succinctly attractive in appearance, has the double seal effect, has effectively solved the little leakage of oil problem in space.
Above embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit, although executing example with reference to previous examples has been described in detail the present invention, those of ordinary skill in the art is to be understood that, it is according to making amendment to the technological scheme of aforementioned each embodiment's record, or its part technical characteristics is equal to replacement, and these modifications or replacement do not make the essence of appropriate technical solution break away from spirit and the category of technical solution of the present invention.
