摘要（英）：

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.
