At present, oil enterprises in China is on oil extraction well mouth equipment energy-saving scheme implementation strategy, and it is single that ubiquity energy-conservation means, and promptly motor variable-frequency speed-regulating is main, and the shutdown mode of production that intermittently has a power failure is the present situation of assisting, and causes energy-conservation not remarkable.The frequency control of motor speed equipment manufacturing cost is high, and working life is short, has caused economic loss in various degree to production unit.

China is in the Rapid development stage of industrialization and urbanization; Energy consumption intensity is increasingly high; The consumption scale constantly enlarges, and the extensive economic growth mode of particularly high investment, high flow rate, high pollution has been aggravated energy availability and demand contradiction and environmental situation.Solve China energy problem, basic outlet is the policy of adhering to " exploitation develops simultaneously, practices thrift preferential with saving ", carries forward vigorously energy-saving and cost-reducingly, improves energy utilization rate.Energy-conservation is to alleviate energy constraint, alleviates external pressure, ensures economy, energy security, the inevitable choice of realize building a well-off society in an all-round way target and sustainable development.

Summary of the invention

The utility model provides a kind of oil field energy-conservation speed reducer of pumping, and energy-conservation not remarkable to solve existing equipment, cost is high, and working life is short, causes environmental pollution problems.

The technological scheme of the utility model is: worm shaft, back shaft, transmission shaft one, clutch shaft one, output shaft, transmission shaft two, clutch shaft two, input shaft are fixedly connected with the retarder seat, and worm gear is fixedly connected with back shaft, worm gear and worm meshing; Cam path is arranged on the worm gear, and an end of connecting rod places cam path, and the other end is connected with push-plate; Worm shaft is fixedly connected with input shaft through coupling, and input shaft gear one, input shaft gear two are fixedly connected with input shaft respectively, and gearwheel one is fixedly connected with transmission shaft one; Gearwheel two is fixedly connected with clutch shaft two, gearwheel one and input shaft gear one engagement, and clutch one is rotationally connected with clutch shaft one; Clutch two is rotationally connected with clutch shaft two; Gearwheel two and input shaft gear two engagements, transmission shaft one right-hand member is fixedly connected with clutch shaft one left end, and clutch shaft two right-hand members are fixedly connected with transmission shaft two left ends; Gear one is fixed on the right-hand member of clutch shaft one and is connected; Gear two is fixedly connected with the right-hand member of transmission shaft two, and output shaft gear is fixedly connected with output shaft, gear one, gear two and output shaft gear engagement.

The working method of the utility model

The advantage of the utility model is: novel structure; It is an oil field truly energy-conservation speed reducer of pumping; Will bring the saving on the very big energy to oil extraction operation; Economically, on working life and on the working state under the rugged environment, all have superiority, very big development space is arranged on market, the profit on market, oil field is also more considerable.
