Description
Technical field
The utility model relates to speed reducers, and in particular to the output terminal protection structure of main speed reducer for ring rolling machine.
Background technique
With the propulsion of national the Belt and Road development strategy, vertical grinder, wind-powered electricity generation of powder industry etc. are energy saving and environment friendly
Industry has obtained significant progress, Ring Rolling Machine using more and more extensive.Because the operation of rolling belongs to hot rolling, the roll temperature of Ring Rolling Machine
Degree is easy to increase failure, so needing often to spray cooling water temperature to roll, so that a large amount of cooling water and oxide skin be caused to pour
The output end of lower section main speed reducer for ring rolling machine leads to oil seal failure, the water inlet of speed reducer inner cavity.
Currently, the output end of traditional main speed reducer for ring rolling machine has the following deficiencies: the oil sealing at 1, output shaft in structure
Cooling water and oxide skin cannot reliably be prevented；2, the oil seal replacement at output shaft need to dismantle output shaft coupler, very troublesome.
Summary of the invention
The purpose of this utility model is that: a kind of output terminal protection structure of main speed reducer for ring rolling machine is provided, is effectively stopped
Cooling water and oxide skin, facilitate the Inspection and maintenance of speed reducer, it is ensured that the lubricating oil in decelerating chassis body outside output end of reducer
It is not emulsified, gear and bearing are not rusted.
The technical solution of the utility model is: the speed reducer includes bearing holder (housing, cover), shaft coupling, output shaft and shell, shell
Output shaft is installed through bearing holder (housing, cover), bearing on body, shaft coupling is installed in the shaft end of output shaft；It is characterized in that: in the output end of output shaft
Safeguard structure is installed, the safeguard structure includes baffle ring, transparent cover and shield, and the inside of shield is equipped with annular groove, transparent cover
Outside wall surface upper design have the oil scraper ring containing fin, shield is mounted on the outer ring step of shaft coupling, and shield is with shaft coupling
Device rotates together, and transparent cover is mounted on shell, and the oil scraper ring of transparent cover protrudes into the annular groove of shield, baffle ring circle in output shaft with
It is mounted on bearing holder (housing, cover) between transparent cover, baffle ring is higher than the upper surface of transparent cover.
The utility model has the advantage that
1, shield and transparent cover use split type combining form, and shield is rotated with shaft coupling, effectively stop the cold of the external world
But water water and oxide skin.
2, the inside of shield is equipped with annular groove, and the outside wall surface upper design of transparent cover has the oil scraper ring containing fin, in annular
Moderate lubrication rouge is squeezed into slot, shield and transparent cover form mechanical labyrinth seal structure, prevent the dust outside speed reducer from entering
Speed reducer inner cavity.
3, baffle ring circle is mounted on bearing holder (housing, cover) between output shaft and transparent cover, and output shaft is using no oil enveloping structure, Ji Kefang
Water facilitates the Inspection and maintenance of speed reducer again.
4, the safeguard structure forms first of protection by shield and transparent cover, then forms second protection, protection by baffle ring
Effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 bearing holder (housing, cover), 2 shaft couplings, 3 output shafts, 4 bearings, 5 baffle rings, 6 shells, 7 shields, 8 transparent covers, 9 gear oil
Ring, 10 annular grooves.
Specific embodiment
Technical solutions of the utility model are further illustrated with reference to the accompanying drawing.
As shown in Figure 1, the speed reducer includes bearing holder (housing, cover) 1, shaft coupling 2, output shaft 3 and shell 6, through bearing holder (housing, cover) on shell 6
1, bearing 4 installs output shaft 3, and shaft coupling 2 is installed in the shaft end of output shaft 3；It is characterized in that: the output end installation in output shaft 3 is anti-
Protection structure, the safeguard structure include baffle ring 5, shield 7 and transparent cover 8, and the inside of shield 7 is equipped with annular groove 10, transparent cover 8
Outside wall surface upper design have the oil scraper ring 9 containing fin, shield 7 is mounted on the outer ring step of shaft coupling 2, shield 7 with
Shaft coupling 2 rotates together, and transparent cover 8 is mounted on shell 6, and the oil scraper ring 9 of transparent cover 8 protrudes into the annular groove 10 of shield 7, baffle ring
5 boundaries are mounted on bearing holder (housing, cover) 1 between output shaft 3 and transparent cover 8, and baffle ring 5 is higher than the upper surface of transparent cover 8.
