Abstract
The utility model discloses a beam -pumping unit cross tailing axle bearing, the kind of drive that is connected who solves original beam -pumping unit walking beam and crossbeam easily leads to the cracked problem of tailing axle bearing bolt. It is concrete including mandrel, bearing frame, support, bearing, location axle and balance staff seat, the bearing frame adopts cross cast structure, and the hole is passed through bearing and is connected with the mandrel cooperation under the bearing frame, and the bearing frame both ends cooperate with the support and are connected, support and crossbeam welding, the hole is connected through location axle and the cooperation of balance staff seat on the above -mentioned bearing frame, balance staff seat and walking beam welding. The use of cross tailing axle bearing, more be favorable to the whole structure's stability, not only reduce cost but also increased the bearing capacity and the adjusting range of tailing axle bearing, improved tailing axle bearing wholeness can, overcome the potential safety hazard that the mainframe beam -pumping unit exists, improved the fail safe nature of complete machine.
Description
Technical field
This utility model relates to beam pumping unit walking beam and is connected drive mechanism with crossbeam, is applied in beam pumping unit design, production.Belong to beam pumping unit design, production technical field.
Background technology
Beam pumping unit walking beam and the connection kind of drive of crossbeam at present: use two bearing footing to be connected with cross beam of oil pumping unit bolt, bearing is connected by axle, hole with bearing block, bolt clamping, bearing block is connected with walking beam bolt again, material is thus formed the connecting rod in oil pumper four bar transmission, the power transmission shaft of fork；Bearing block is internal uses single radial roller bearing, and in running with this bearing buffering oil pumper, walking beam swings the impact on integrated model.But, for bigger type, tailstock stress is very big, and tailstock connecting bolt diameter is the biggest, again it is difficult to ensure that reach requirement in fastening, if occurring to loosen, arises that the situation of bolt fracture, tailstock bolt fracture will cause great turning over machine accident after a period of time.
Summary of the invention
The purpose of this utility model is to provide a kind of beam pumping unit cross tailing axle bearing, and this bearing block changes beam pumping unit tailstock and crossbeam, the connected mode of walking beam, solves tailing axle bearing bolt fracture problem.
In order to realize foregoing invention purpose, the technical solution adopted in the utility model is: a kind of beam pumping unit cross tailing axle bearing, including mandrel, bearing block, bearing, needle bearing, locating shaft and oscillating shaft seat, described bearing block uses cross cast structure, bearing block lower opening is connected with mandrel by needle bearing, bearing block two ends are connected with bearing, described bearing and beam welding；On above-mentioned bearing block, hole is connected with oscillating shaft seat by locating shaft, and described oscillating shaft seat welds with walking beam.
The beneficial effects of the utility model: the cross tailing axle bearing of the application, change the tailstock of traditional structure and the connected mode of 4 bolts of walking beam, avoid the machine that the turns over accident caused because of tailstock bolt fracture, the version of cross axle is compared with the structure that protocercal tail bearing block uses self-aligning roller bearing simultaneously, in buffering teeter, adjustable amplitude is bigger, it is more beneficial for the stability of complete machine structure, not only reduce cost but also add bearing capacity and the adjusting range of tailing axle bearing, improve tailing axle bearing overall performance, overcome the potential safety hazard that large scale computer oil pumper exists, improve the security reliability of complete machine.
