Abstract
The utility model provides the connection structure of a kind of reduction gearbox and abat-vent, is connected between reduction gearbox and abat-vent using vent line, and, the reduction gearbox of formation zigzag structure and the vent line of abat-vent curved there are two transferring are set on vent line.The utility model can prevent at gear splash lubricating oil through abat-vent splash to reduction gearbox outside, speed reducer insufficient lubrication bring stability declines problem caused by avoiding lubricating oil from persistently reducing because of splash, lubricating oil is saved, hygienic issues caused by greasy dirt are prevented, has achieved the effect that subtract consumption synergy.
Description
Technical field
The utility model belongs to transmission machinery field, more particularly to one kind can prevent the reduction gearbox of oil liquid splash and lead to
The connection structure of gas cap.
Background technique
Temperature increases speed reducer at work, and gas expansion in reduction gearbox, pressure rises.In order to prevent from Gearbox
Seam and axis sealing at oil leak, it is necessary to hot-air in reduction gearbox is discharged from abat-vent, balances the interior external pressure of speed reducer
Power.
External screw thread is had on original abat-vent ontology, abat-vent is directly installed on the upper cover boss of reduction gearbox by screw thread
On.Such connection structure leads to a large amount of lubricating oil to splash at gear, by the effect of reduction gearbox inside and outside differential pressure, from ventilation
Cap splash is to the outside of speed reducer.Due to splash lubricating oil can not recycling and reusing, cause waste and greasy dirt problem.In addition,
Due to the lasting reduction of lubricating oil, the lubrication of speed reducer internal gear and bearing is seriously affected, makes speed reducer that insufficient lubrication easily occur
Equipment breakdown.
Summary of the invention
The utility model be intended to provide one kind can prevent lubricating oil through abat-vent splash to reduction gearbox outside, save grease, subtract
Few greasy dirt, avoids the reduction gearbox of speed reducer insufficient lubrication and the connection structure of abat-vent.
The technical solution that the utility model is taken are as follows:
A kind of connection structure of reduction gearbox and abat-vent is connected between reduction gearbox and abat-vent using vent line, and logical
, the reduction gearbox of formation zigzag structure and the vent line of abat-vent curved there are two transferring are set on air pipe.
The utility model has the following beneficial effects:
The utility model can be effectively prevented at gear splash lubricating oil through abat-vent splash to reduction gearbox outside, avoid
Speed reducer insufficient lubrication bring stability declines problem caused by lubricating oil is persistently reduced because of splash, while saving lubricating oil,
Hygienic issues caused by greasy dirt are prevented, have achieved the effect that subtract consumption synergy.
Detailed description of the invention
Fig. 1 is cold coiling machine reduction gearbox and abat-vent attachment structure schematic diagram.
In figure: abat-vent 1, vent line 2, reduction gearbox 3, shaft coupling 4, motor 5, low-speed gear axis 6, intermediate gear axis 7,
High speed gear shaft 8.
Specific embodiment
Below by taking cold coiling machine reduction gearbox and abat-vent connection structure as an example, the utility model is described in further detail.
As seen from Figure 1, the motor 5 of cold coiling machine transmission system connects speed reducer by shaft coupling 4, and low speed tooth is arranged in reduction gearbox 3
Wheel shaft 6, intermediate gear axis 7,8 tertiary gear axis of high speed gear shaft.
Original abat-vent 1 is directly installed on by the connection structure of the utility model reduction gearbox 3 and abat-vent 1 by screw thread
On the upper lid of reduction gearbox 3, be changed between reduction gearbox 3 and abat-vent 1 connect using vent line 2, set on vent line 2 there are two
Right angle turns are curved, form the reduction gearbox 3 of zigzag structure and the vent line 2 of abat-vent 1.
Since vent line 2 is equipped at two, turnover is curved, and lubricating oil splash can be effectively prevent to the outside of abat-vent 1, thus
It drips the lubricating oil of splash at once first curved position of turnover, and gradually flows back into reduction gearbox 3.
Claims (1)
1. the connection structure of a kind of reduction gearbox and abat-vent, which is characterized in that use vent line between reduction gearbox and abat-vent
Connection, and, the reduction gearbox of formation zigzag structure and the vent line of abat-vent curved there are two transferring are set on vent line.
