Abstract
The utility model relates to a special planetary gear train for an oil pipe wrench, including a gearbox body, a motor connecting plate, a planetary carrier, a planetary gear, a gear rack needle rollerbearing and a gear shaft needle roller bearing. The motor connecting plate and the gearbox body are split. The planetary carrier is in the center of the gearbox body. The planetary gear shaft is installed on the planetary carrier. The planetary gear is engaged with the annular gear fixed on the gearbox body by a location pin. The utility model improves the production efficiency of the oil pipe wrench for repairing the well in the oil field at home, reduces the work cost, ensures the work quantity and improves the durability of the oil pipe wrench. The special planetary gear train has light weight, small volume, high transmission ratio and high efficiency, integrity, convenient operation, safe and reliable work and good applicability.
Description
Technical field
The utility model relates to the planetary type gear transmission unit of mechanical manufacturing field, be specifically related to planetary type gear transmission unit in the oil field well workover with the application on the tubing tongs.
Background technique
In oil well repairing operation, used hydraulic tubing tong equipment to substitute manual operation, reduced damage to oil pipe, improved working efficiency.Along with the raising of market demands, operation quality requires more and more higher, and hydraulic tubing tong deficiency in use also occurs thereupon, and repair rate constantly raises, and durability is not enough.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of operating cost that reduces is provided, and guarantees operation quality, reduces the special-purpose planetary type gear transmission unit of tubing tongs of tubing tongs repair rate.
The purpose of this utility model is achieved through the following technical solutions.
The special-purpose planetary type gear transmission unit of a kind of tubing tongs, it comprises parts such as gearbox casing, motor joining plate, planetary carrier and planetary pinion, gear carrier needle bearing and gear shaft needle bearing; Motor joining plate and gearbox casing are split type, and planetary carrier is positioned at the central position of gearbox casing, and planet pin is installed on the planetary carrier, and planetary pinion is meshed with ring gear.Ring gear is fixed on the gearbox casing by locating stud; The end of planetary carrier is by gear carrier needle bearing and gearbox casing engagement.
The utility model has improved the manufacturing efficiency of domestic oil field well workover with tubing tongs, has reduced operating cost, has guaranteed operation quality, has reduced the repair rate of tubing tongs, has improved the durability of tubing tongs.This planetary pinion transmission with ordinary gear transmission compare have in light weight, volume is little, velocity ratio is big, the efficient advantages of higher.Therefore, realized combined integratedly, easy to operate, safe and reliable, had favorable applicability and reliability.
