Abstract

The invention relates to a belt pulley in a belt driving mechanism, in particular to an intelligent belt pulley for walking beam type pumping unit in oil fields. The invention solves the problems that: the prior speed reducer and belt driving mechanism for walking beam type pumping unit can not meet the requirements of long-stroke low-frequency pumping units and the energy-saving requirements of a matched low power motor. The intelligent belt pulley comprises a planet gear mechanism consisting of a sun wheel, an annular gear, a planet carrier and a planet gear, and a belt pulley consisting of a belt pulley core and a belt pulley, wherein the belt pulley core is axially fixed on a planet carrier shaft through a bearing, the sun wheel is in floating connection with the belt pulley core, the annular gear is surrounded by an external friction tape, one end of the friction tape is fixed on a connecting plate on the body of the speed reducer, the other end of the friction end is fixed on a screw which passes through the connecting plate and is fixed through a nut. The invention which has reasonable and simple structure, high mechanical efficiency and lower power consumption can meet the requirements of long-stroke low-frequency pumping units in various types of oil fields and is also applicable to other universal machines.

Description

technical field [0001] The invention relates to a belt pulley in a belt transmission mechanism, in particular to an intelligent belt pulley used for a beam pumping unit in an oil field. Background technique [0002] Most of my country's oil fields are low-energy and low-yield oil fields. Unlike foreign oil fields, which have strong self-spraying capabilities, most oil fields rely on water injection to press oil into the well, and pumping units (also known as kowtow machines) pump oil from the formation. Raise up. At present, the number of pumping units in my country is more than 100,000, the total installed capacity of electric motors is 3500MW, and the annual power consumption exceeds 10 billion kW·h. At present, the operating efficiency of pumping units is extremely low, with an average operating efficiency of 25.96% in my country and 30.05% abroad, and the annual energy saving potential can reach several billion kW·h. In recent years, the number of heavy oil wells, gas-b...
