Abstract
The utility model discloses a kind of structure improved comprehensive machine Juan Xie mechanism, comprise fixed plate, bearing, oil pressure oil sealing, cover plate, volume bits screw rod and screw axis, bearing is installed in fixed plate, one end that step-like screw axis diameter is little is inserted in bearing, one end that screw axis diameter is large is considered screw rod to be worth doing with volume and is connected, fixed plate is considered to be worth doing inside screw rod one end towards volume and is formed ring between screw axis and forms containing groove, oil pressure oil sealing just seals to be located in this containing groove, fixed plate is also installed with a cover plate on the end face of volume bits screw rod one end, cover plate backstop is in oil pressure oil sealing axial end, V-arrangement oil sealing is also arranged with outside described screw axis, this V-arrangement oil sealing just seals in the junction plane gap that is placed in and formed between the screw axis step surface that extends out of radial direction and the cover plate of fixed plate one end, the utility model realizes the double seal of bearing, effectively prevent chip and other impurity from entering Bearing inner, its structure is simple, good airproof performance, ease of assembly, cost is lower, easy to maintenance.
Description
Technical field
The utility model relates to a kind of sealing mechanism, espespecially relates to a kind of structure improved comprehensive machine Juan Xie mechanism.
Background technique
In comprehensive machine Juan Xie mechanism operationally, a large amount of chips and dust can be produced, once these chips and dust enter in bearing in gap, wearing and tearing will be caused to bearing, cause bearing damage, current Juan Xie mechanism bearing tightly realizes sealing by oil pressure oil sealing, sealing is poor, also has chip and dust enters in bearing in gap, causes comprehensive machine Juan Xie mechanism bearing frequent breakage to change, reduce work efficiency, improve processing cost.
Model utility content
In order to overcome above-mentioned defect, the utility model provides a kind of structure improved comprehensive machine Juan Xie mechanism, and this structure improved comprehensive machine volume bits mechanism structure is simple, ease of assembly, manufacture cost, can effectively prevent chip and other impurity from entering Bearing inner, extends bearing working life.
The utility model in order to the technological scheme solving its technical problem and adopt is: a kind of structure improved comprehensive machine Juan Xie mechanism, comprise fixed plate, bearing, oil pressure oil sealing, cover plate, volume bits screw rod and screw axis, described bearing is installed in fixed plate, one end that step-like screw axis diameter is little is inserted in bearing, one end that screw axis diameter is large is considered screw rod to be worth doing with volume and is fixedly connected with, fixed plate is considered to be worth doing inside screw rod one end towards volume and is formed ring between screw axis and forms containing groove, oil pressure oil sealing just seals to be located in this containing groove, fixed plate is also installed with a cover plate on the end face of volume bits screw rod one end, cover plate backstop is in oil pressure oil sealing axial end, V-arrangement oil sealing is also arranged with outside described screw axis, this V-arrangement oil sealing just seals in the junction plane gap that is placed in and formed between the screw axis step surface that extends out of radial direction and the cover plate of fixed plate one end.
As further improvement of the utility model, described two oil pressure oil sealing axially-aligned are located in the containing groove that fixed plate and screw axis formed.
As further improvement of the utility model, the step root that described screw axis is adjacent with cover plate is formed with concave ring groove in a circle, and V-arrangement oil sealing is just sheathed in this interior concave ring groove.
The beneficial effects of the utility model are: the utility model is by arranging V-arrangement oil sealing in the junction plane gap between the screw axis step surface that extends out of radial direction and the cover plate of fixed plate one end, realize the double seal of bearing, effectively prevent chip and other impurity from entering Bearing inner, extend bearing working life, this volume bits mechanism seals structure is simple, good airproof performance, ease of assembly, cost are lower, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model.
Embodiment
Embodiment: a kind of structure improved comprehensive machine Juan Xie mechanism, comprise fixed plate 1, bearing 2, oil pressure oil sealing 3, cover plate 4, volume bits screw rod 5 and screw axis 6, described bearing 2 is installed in fixed plate 1, one end that step-like screw axis 6 diameter is little is inserted in bearing 2, one end that screw axis 6 diameter is large is considered screw rod 5 to be worth doing with volume and is fixedly connected with, fixed plate 1 is considered to be worth doing inside screw rod 5 one end towards volume and is formed ring between screw axis 6 and forms containing groove, oil pressure oil sealing 3 just sealing is located in this containing groove, fixed plate 1 is also installed with a cover plate 4 on the end face of volume bits screw rod 5 one end, cover plate 4 backstop is in oil pressure oil sealing 3 axial end, V-arrangement oil sealing 7 is also arranged with outside described screw axis 6, this V-arrangement oil sealing 7 just sealing is placed in the junction plane gap formed between step surface and the cover plate 4 of fixed plate 1 one end that screw axis 6 radial direction extends out, principle: bearing 2 is arranged in fixed plate 1, right-hand member is installed oil pressure oil sealing 3 and is sealed, outside is being protected with end cap, a V-type oil sealing sealing is used in junction plane gap outside end cap again, the protection to internal bearings 2 is realized by the matching relationship of oil pressure oil sealing 3 and V-type oil sealing.Effectively prevent chip and other impurity from entering bearing 2 inner, extend bearing 2 working life, this volume bits mechanism seals structure is simple, and good airproof performance, ease of assembly, cost are lower, easy to maintenance.
Described two oil pressure oil sealing 3 axially-aligned are located in the containing groove that fixed plate 1 and screw axis 6 formed, and two oil pressure oil sealings 3 ensure sealing.
The step root that described screw axis 6 is adjacent with cover plate 4 is formed with concave ring groove in a circle, and V-arrangement oil sealing 7 is just sheathed in this interior concave ring groove, avoids V-arrangement oil sealing 7 to be shifted, guarantees sealing.
