Description
Technical field
This utility model is related to oil drilling cementing technology field, more particularly to a kind of integral type semi-ring driving-shaft assembly.
Background technology
At present, due to using the dynamic set deflection of rear lower TC bearings big, 40% cannot dismantle the semi-ring power transmission shaft for now using, and make
It is too high into maintenance cost；When using powerful motor, because mud pumpage too big or use time is long, easily there is axle
Primary drying deteriorates bad phenomenon, causes power transmission shaft premature failure.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and it is total to provide a kind of integral type semi-ring power transmission shaft
Into preventing spindle nose premature breakdown, maintenance easy to disassemble.
This utility model for achieving the above object, is employed the following technical solutions：
A kind of integral type semi-ring driving-shaft assembly, including water cap, upper dynamic set, upper quiet set, thrust bearings, spacer, pressure-bearing
Set, semi-ring, housing, the quiet set of lower TC bearings, integral type power transmission shaft, erosion control set, adjusting pad and woodruff key；The thrust bearings
It is arranged between the housing and the integral type power transmission shaft, the pressure-bearing set and semi-ring are installed in the side of the thrust bearing,
Pressure-bearing covers and semi-ring and the housing between and arranges the spacer, and the lower TC bearings are quiet to be covered installed in the lower end of the housing；
The opposite side of the thrust bearings is provided with the upper quiet set, by described half between the upper quiet set and the housing upper
Round key is fixed, and the water cap and upper dynamic set are installed in the upper end of the integral type power transmission shaft, it is characterised in that：The integral type is passed
The upper end of moving axis is provided with mounting groove, and hard alloy erosion control set is provided with the mounting groove；The lower end of the integral type power transmission shaft
Being coated with can repair wearing layer.
The beneficial effects of the utility model are:Compared with prior art, this utility model simple structure is easy to process, drop
Low production cost, changes accessory conveniently, and in transmission shaft head upper end Anti-erosion hard alloy sleeve is increased, and uses power transmission shaft axis body
Life-span is effectively extended；
Because integral type semi-ring driving-shaft assembly bottom eliminates the dynamic set of lower TC bearings, the overall length for making whole power transmission shaft shortens
65mm, makes the power transmission shaft in use, and rate of increase of angle is improved；Bottom wear-resistant coating receiving during compound drilling
Power and abrasion have different degrees of reduction.
The dynamic set of power transmission shaft axis body and lower TC bearings is made of one, power transmission shaft axis body lower end adopts spraying wear-resistant materials, resistance to
Mill material be can reparation, after use axis body abrasion after, axis body can again carry out spraying reparation, and inner space is released
Put, axis body can increase in right amount slightly, and easy accessibility, cost efficiency, safety coefficient are higher.

Specific embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.As shown in figure 1, one
Plant integral type semi-ring driving-shaft assembly, including water cap 1, upper dynamic set 2, upper quiet set 3, thrust bearings 4, spacer 5, pressure-bearing set 6, half
Quiet set 9, integral type power transmission shaft 10, the erosion control set 11, adjusting pad 12 of ring 7, housing 8, lower TC bearings and woodruff key 13；The thrust
Bearing group is arranged between the housing and the integral type power transmission shaft, the side of the thrust bearing install the pressure-bearing set and
Semi-ring, arranges the spacer between pressure-bearing set and semi-ring and the housing, the lower TC bearings are quiet to be covered installed in the housing
Lower end；The opposite side of the thrust bearings is provided with the upper quiet set, passes through between the upper quiet set and the housing upper
The woodruff key is fixed, and the water cap and upper dynamic set are installed in the upper end of the integral type power transmission shaft, it is characterised in that：Described one
The upper end of body formula power transmission shaft is provided with mounting groove, and hard alloy erosion control set is provided with the mounting groove；The integral type power transmission shaft
Lower end be coated with and can repair wearing layer.Bottom axis body can repair the method for wear-resistant coating using spraying, eliminate lower TC bearings
Dynamic set.
The drive shaft body bottom, its outside dimension increase, it is different according to model that older intended diameter increases 10%-20%
Increase degree is also different.（Such as 172 increase to 136mm by former 113mm.）
This utility model simple structure is easy to process, reduces production cost, accessory is changed conveniently, in transmission shaft head upper end
Increase Anti-erosion hard alloy sleeve, power transmission shaft axis body service life is effectively extended；
Because integral type semi-ring driving-shaft assembly bottom eliminates the dynamic set of lower TC bearings, the overall length for making whole power transmission shaft shortens
65mm, makes the power transmission shaft in use, and rate of increase of angle is improved；Bottom wear-resistant coating receiving during compound drilling
Power and abrasion have different degrees of reduction.
The dynamic set of power transmission shaft axis body and lower TC bearings is made of one, power transmission shaft axis body lower end adopts spraying wear-resistant materials, resistance to
Mill material be can reparation, after use axis body abrasion after, axis body can again carry out spraying reparation, and inner space is released
Put, axis body can increase in right amount slightly, and easy accessibility, cost efficiency, safety coefficient are higher.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
