Abstract
The utility model discloses a waterproof device of a reduction gearbox, which is characterized in that a coupler is connected with a main roll shaft which is provided with a conic cap; and the connecting position between the conic cap and the main roll shaft is provided with two O-type sealing groove loops; the upper end of the coupler is provided with a waterproof cover, and the connecting position between the waterproof cover and the coupler is also provided with two O-type sealing loops; the bottom end of an upper cover body is provided with a flange which is connected and matched with a middle flange for fixing a waterproof plate; the outline of the waterproof plate is identical with that of the top surface of the reduction gearbox. By adopting the design, cooling water and oxidation scrap iron can be hold when falling down during working, so that the cooling water and the oxidation scrap iron do not fall off the surface of the reduction gearbox directly.
Description
Technical field
The utility model design relates to a kind of reduction box water-tight device of Ring Rolling Machine, specifically is used for the forging processing of annular element (bearing ring, flange etc.), belongs to the machining equipment technical field.
Background technology
The main transmission reduction box of existing horizontal Ring Rolling Machine equipment all is in underground foundation, is positioned at the home roll below, and reduction gearbox output shaft is connected by shaft coupling with the home roll axle.Ring Rolling Machine belongs to hot forging equipment, mould must constantly cool off during work, home roll is main rolling mould, must carry out continual cooling to it during work, therefore the cooling water that carries the oxide skin iron filings can constantly flow in the melt pit down, wherein the part cooling water can be axially dirty along home roll, flow to down in the shaft coupling by upper coupling, then flow in the bearing of output shaft, thereby enter in the reduction box, make that the lubricating oil in the casing is damaged, lubricated destroyed with cooling performance, bearing and gear in the casing are damaged, and the life-span reduces.Therefore must prevent that water from flowing in the reduction box.Existing water-tight device general all is made up of the bucker that is divided into vertical two halves, and such waterproof construction sealing property is also bad, and cooling water still can flow in the reduction box along home roll.
Summary of the invention
Problem to be solved in the utility model is that a kind of water-tight device safely and effectively will be provided, and prevents that cooling water from flowing into shaft coupling and entering in the deceleration box, can guarantee the normal safe handling of reduction box, in the service life of prolonged mechanical, enhances productivity.
Main solution of the present utility model is achieved in that shaft coupling is connected with the home roll axle, on the home roll axle, be provided with an awl cap, awl cap and home roll shaft connection place are provided with twice O type seal groove circle, be provided with a bucker in the upper end of shaft coupling, bucker and shaft coupling junction also are provided with twice O RunddichtringO, be provided with a ring flange in the bottom of upper outlet body, ring flange and middle flange are connected and splash guard are fixed, the profile of splash guard is consistent with the end face profile phase of reduction box, from top fallen cooling water and oxide skin iron filings, it can directly not dropped on the reduction box upper surface in the time of can catching work like this.We vertical split typely change into original laterally split typely like this, the sealing property of whole staving is strengthened, and be added with four road seal with O rings, make sealing more safe and reliable.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram
Lower flange 1, middle flange 2, splash guard 3, upper outlet body 4, bucker 5, O RunddichtringO 6, awl cap 7, O RunddichtringO 8, home roll axle 9, shaft coupling 10 among the figure
The specific embodiment
As shown in Figure 1, issue blue 1 and be welded on the lower barrel body bottom, middle flange 2 is welded on lower barrel body top, splash guard 3 is screwed on middle flange 2, ring flange of upper outlet body 4 bottoms welding, this ring flange matches with middle flange and pushes down splash guard 3, the structure of upper outlet body 4 as shown in Figure 1, above the plectane weldering that staving top has a circular hole with a centre is blocked, be welded with an illustrated thin neck bucket on the plectane face, bucker 5 is installed from upper coupling 10 tops, is fixed on the upper coupling 10 with screw.Twice O RunddichtringO groove is arranged in the bucker 5,2 O RunddichtringOs 6 are housed during installation, can play waterproof action.Awl cap 7 is installed on the upper end home roll axle 9 of shaft coupling 10, and awl cap 7 is formed by truncated cone cap body and cap sleeve assembly welding.Twice seal with O ring groove is also arranged in the cap body, twice O shape circle 8 is installed, coat an amount of marine glue in the junction of awl cap 7 and home roll axle 9 again during installation.The profile of splash guard 3 is consistent with the end face profile phase of reduction box, from top fallen cooling water and oxide skin iron filings, it can directly not dropped on the reduction box upper surface in the time of can catching work like this.
