Abstract
The invention relates to the field of petroleum engineering equipment, in particular to a winch. The winch comprises a first speed changing device, rollers, a first speed changing device output shaft, a first bearing and a second bearing. The first speed changing device output shaft is connected with the rollers in an extending manner. The first bearing is connected with the first speed changing device output shaft, and the second bearing is connected with the first speed changing device output shaft. Due to the structure, the size is reduced, the weight is reduced, the service life is prolonged, and the purposes of reducing cost and improving efficiency are achieved.
Description
Technical field
The present invention relates to petroleum works apparatus field, and in particular to a kind of winch.
Background technology
At present, hoist gearbox of petroleum drilling machine output shaft couples general using independent tooth-like shaft coupling with the transition of drum shaft
Device, the axial length dimension shared by this layout structure and weight are all very big, during for structure and limited space, increased
Design difficulty, accordingly increases rig size, for marine mining platform, poor for applicability；Also have using gear-box and drum shaft
Associated mode is to reduce space length, however, due to two bearing alignment error of cylinder, particularly cylinder is worked in high-speed rotation
Cheng Zhong, due to being for a long time subject to cable radial pull, makes drum shaft produce flexural deformation, and deformation causes to the drum shaft and above tooth
Roller box drive system produces destruction, greatly reduces reliable transmission, shortens service life, improves use cost.

In view of this, it is necessary to which a kind of easily a kind of winch is provided.
A kind of winch, including
First speed change gear；
First transmission output shaft；
Cylinder；
It is characterized in that：
First transmission output shaft extends the connection cylinder.
A kind of described winch, it is characterised in that：
Also include
Clutch shaft bearing；
Second bearing；
The clutch shaft bearing connects first transmission output shaft；
The second bearing connects first transmission output shaft.
First speed change gear is planetary reduction gear.
A kind of winch, including：
First speed change gear；
First transmission output shaft；
Rope draw off gear；
Second speed change gear；
First transmission output shaft extends the connection rope draw off gear；
First transmission output shaft extends connection second speed change gear.
A kind of described winch, it is characterised in that：
Also include
Clutch shaft bearing；
Second bearing；
The clutch shaft bearing connects first transmission output shaft；
The second bearing connects first transmission output shaft.
First speed change gear is planetary reduction gear；
Second speed change gear is planetary reduction gear.
Due to employing technique scheme, the invention has the beneficial effects as follows：
Volume is this arrangement reduces, weight is alleviated, service life is extended, reduces cost has been reached, carry efficient mesh
's.
