Abstract
The utility model discloses a kind of vertical type speed reducer (change gear) with vertical shaft bearing lubrication oil circulation device, including vertical type speed reducer (change gear) body, on the gear-box bottom wall of the vertical type speed reducer (change gear) body, oil guide pipe is provided with the gear-box power output shaft lower bearing room position, a mouth of pipe of the oil guide pipe is connected with the lower bearing room and another mouth of pipe is connected with the oil sump in gear-box；The lower end of the gear-box power output shaft is extended in bearing chamber, and impeller is fixed with the gear-box power output shaft extended in bearing chamber.The utility model advantage is to realize the lubricating oil forced circulation in power output shaft lower bearing room, it is therefore prevented that the lubricating oil at lower bearing room position of bearings cannot be circulated and bearing temperature rise superelevation phenomenon occurs caused by contamination precipitation.
Description
Technical field
The utility model is related to vertical type speed reducer (change gear), more particularly, to vertical the subtracting with vertical shaft bearing lubrication oil circulation device
Fast machine.
Background technology
Vertical type speed reducer (change gear) is widely used in large-scale powder process equipment such as vertical pulverizer, its vertical shaft（Power output shaft）As
Active force drives grinding machine work.The bottom bearing of vertical type speed reducer (change gear) vertical shaft is arranged in bearing holder (housing, cover), and bearing holder (housing, cover) is attached or connected to
On deceleration machine bottom board, it is immersed directly in gear-box oil sump.Vertical type speed reducer (change gear) work when into the lubricating oil inside bearing holder (housing, cover) because
The cup-like structure of bearing holder (housing, cover), causes the lubricating oil in bearing holder (housing, cover) to be difficult to swap and follow with the lubricating oil in gear-box oil sump
Ring, causes oil deterioration fast, and impurity is easily deposited in bearing holder (housing, cover), causes that bearing heating is serious, bearing service life is short.
The content of the invention
The utility model purpose is to provide a kind of vertical type speed reducer (change gear) with vertical shaft bearing lubrication oil circulation device.
To achieve the above object, the utility model takes following technical proposals：
Vertical type speed reducer (change gear) with vertical shaft bearing lubrication oil circulation device described in the utility model, including vertical type speed reducer (change gear) sheet
Body, sets on the gear-box bottom wall of the vertical type speed reducer (change gear) body, at the gear-box power output shaft lower bearing room position
Oil guide pipe is equipped with, a mouth of pipe of the oil guide pipe is connected and the oil sump phase in another mouth of pipe and gear-box with the lower bearing room
Connection；The lower end of the gear-box power output shaft is extended in bearing chamber, positioned at the gear-box power extended in bearing chamber
Impeller is fixed with output shaft.
Oil guiding hole is offered on the side wall of the lower bearing room.
The utility model advantage is to realize the lubricating oil forced circulation in power output shaft lower bearing room, it is therefore prevented that lower axle
Holding the lubricating oil at the position of bearings of room cannot circulate and bearing temperature rise superelevation phenomenon generation caused by contamination precipitation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Embodiments of the invention are elaborated below in conjunction with the accompanying drawings, the present embodiment is with technical solution of the present invention as preceding
Put and implemented, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in figure 1, the vertical type speed reducer (change gear) with vertical shaft bearing lubrication oil circulation device described in the utility model, including it is vertical
Formula reductor body 1, on the bottom wall of gear-box 2 of vertical type speed reducer (change gear) body 1, positioned at the lower bearing room 4 of 2 power output shaft of gear-box 3
End cap 7 is provided with position, the bottom of end cap 7 is provided with oil guide pipe 5, and a mouth of pipe of oil guide pipe 5 is connected and another with lower bearing room 4
One mouth of pipe is connected with the oil sump 6 in gear-box 2；Impeller 8 is fixed with the power output shaft 3 in the cavity of bearing chamber 4；For
The circulating effect of lubricating oil is further improved, oil guiding hole 9 is offered on the side wall of lower bearing room 4.
During utility model works, the impeller 8 of gear-box power output shaft 3 rotates, and promotes the lubrication in lower bearing room 4
Oil being axially formed pressure and flow, in the oil sump 6 that the lubricating oil of flowing is imported into gear-box by oil guide pipe 5, so that right
Bearing body in lower bearing room 4 carries out self-contained lubrication, while also reducing the operating temperature of bearing body, extends bearing body
Service life.
