Description
Technical field
This utility model relates to gear spindle drive technical field, particularly to rolling gear of turbine transmission shafts
Set.
Background technology
Between axle sleeve and the axle of existing rolling gear of turbine, less (processor generally individually presses axle and axle sleeve in gap
Maximum solid processing, i.e. lower deviation is partial in gap between axle and axle sleeve), once lubricating oil has foreign body will
Gap blocking between axle sleeve and axle, insufficient lubrication, especially 5P axle and idler shaft are when barring gear operates
This two axles rotating speed is low and stress is maximum, almost cannot set up oil film between axle and axle sleeve, semi-dry friction occurs
Phenomenon, the coefficient of friction between axle and copper bush increases, and copper bush is the most easily worn.Copper bush weares and teares
There is groove in rear inner surface, and the copper scale under grinding off, in very fine particulate and fine platy, enters oil system in a large number,
Cause oil system to pollute, invent a kind of rolling gear of turbine propeller shaft tube to solve problem above spy.
Utility model content
This utility model aims to overcome that the deficiencies in the prior art, and provides a kind of simple in construction to have well
Lubricating function and the rolling gear of turbine propeller shaft tube of abrasion-resistance.
To achieve these goals, this utility model adopts the following technical scheme that realization: a kind of steam turbine dish
Car device propeller shaft tube, including: sleeve member, lubricating oil return mouth part, shaft sleeve lubricating oil sac part, lubrication
Oil oil-in part；Described sleeve member is aluminium bronze, and the right-hand member bottom it is provided with lubricating oil return mouth part,
Described shaft sleeve lubricating oil sac part is arranged on the inside of sleeve member, and its length is less than the length of sleeve member；Described
Lubricating oil oil-in part be arranged on the upper end of shaft sleeve lubricating oil sac part and communicate with shaft sleeve lubricating oil sac part；Described
Shaft sleeve lubricating oil sac part become 120 ° of angles with lubricating oil return mouth part.
This utility model: there is high wearability and processing characteristics and lubricity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Detailed description of the invention
In order to be better understood from the technical solution of the utility model, describe this practicality below in conjunction with the accompanying drawings in detail new
The embodiment that type provides.
A kind of rolling gear of turbine propeller shaft tube, including: sleeve member 101, lubricating oil return mouth part 102,
Shaft sleeve lubricating oil sac part 103, lubricating oil oil-in part 104；Described sleeve member 101 is tin bronze, its end
The right-hand member in portion is provided with lubricating oil return mouth part 102, and described shaft sleeve lubricating oil sac part 103 is arranged on sleeve member
The inside of 101, its length is less than the length of sleeve member 101；Described lubricating oil oil-in part 104 is arranged on
The upper end of shaft sleeve lubricating oil sac part 103 communicates with shaft sleeve lubricating oil sac part 103；Described shaft sleeve lubricating oil sac
Part 103 becomes 120 ° of angles with lubricating oil return mouth part 102.
In the above-described embodiments, in order to meet a kind of rolling gear of turbine transmission shafts of system tightness requirement
Overlap the material to part 101 to be changed, original tin bronze (QSn4-4-4) become crush resistance strength
Higher, it is easy to manufacture processing aluminium bronze (QA19-4).
A kind of rolling gear of turbine propeller shaft tube row of being thered is provided this utility model embodiment above is in detail
Thin introduction, for one of ordinary skill in the art, according to the thought of this utility model embodiment, specifically
All will change on embodiment and range of application, in sum, this specification content should not be construed as
To restriction of the present utility model.
