Abstract
The utility model is related to a kind of oil pumping unit brake link gearings.It mainly solves the problems, such as existing oil pumping unit brake transmission device easy-to-rust and causes skidding hydraulic performance decline.It is characterized in that：The transmission shaft（4）Outer surface opens that there are two circumferential seal grooves（2）, seal groove（2）Axle bed is corresponded to respectively（5）Both ends, and seal groove（2）It is equipped with sealing ring（3）.The oil pumping unit brake link gearing good airproof performance, can prevent rainwater and sundries from entering in axle bed, avoid transmission shaft corrosion.
Description
Technical field
The utility model is related to oilfield, specifically a kind of oil pumping unit brake link gearing.
Background technology
The effect of oil pumping unit brake link gearing is the lateral brake rocker of connection and longitudinal brake rocker, passing power
Realize the braking to pumping unit.Due between transmission shaft and axle bed there are fit clearance, rainwater, snow-broth in open-air atmosphere outdoors
And sundries is easily invaded in gap, is made transmission shaft corrosion, rotation dumb, skidding hydraulic performance decline is caused to there is safety hidden
Suffer from；In addition transmission shaft is not to often result in waste and equipment pollution after closed oiling.
Invention content
Skidding hydraulic performance decline is caused in order to overcome the shortcomings of existing oil pumping unit brake transmission device easy-to-rust, this reality
With a kind of oil pumping unit brake link gearing of novel offer, which can prevent
Rainwater and sundries enter in axle bed, avoid transmission shaft corrosion.
The technical solution of the utility model is：A kind of oil pumping unit brake link gearing, including transmission shaft, transmission shaft is put
In in axle bed, and both ends of the drive shaft connects longitudinal brake rocker and lateral brake rocker respectively, and the transmission shaft outer surface is provided with
The seal groove of two circumferential directions, seal groove corresponds to axle bed both ends respectively, and seal groove is equipped with sealing ring.
It is interference fit between the sealing ring and axle bed.
The utility model has the advantages that：Due to taking said program, both ends of the drive shaft is provided with seal groove, sealing
Slot is built-in with sealing ring, and is interference fit between sealing ring and axle bed.It can make to realize closed oiling in axle bed in this way, avoid
Waste；Rainwater snow-broth and sundries is avoided to enter in axle bed and cause corrosion to transmission shaft simultaneously；It can ensure that transmission shaft rotates freely,
Flexibility and reliability is operated, ensures skidding performance.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
1- longitudinal directions brake rocker in figure, 2- seal grooves, 3- sealing rings, 4- transmission shafts, 5- axle beds, 6- transverse direction brake rockers.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of oil pumping unit brake link gearing, including transmission shaft 4, transmission shaft 4 is placed in axle bed 5,
And 4 both ends of transmission shaft connect longitudinal brake rocker 1 and lateral brake rocker 6 respectively.Axle bed 5 is equipped with oil nozzle, can be into axle bed 5
Portion adds lubricating oil.4 outer surface of transmission shaft is opened there are two circumferential seal groove 2, and seal groove 2 corresponds to 5 both ends of axle bed respectively, and
Seal groove 2 is equipped with sealing ring 3, is interference fit between the sealing ring 3 and axle bed 5, can be effectively by transmission shaft 4 and axle bed
Clearance seal between 5.
The oil pumping unit brake link gearing processing cost is low, can prevent in rainwater, snow-broth and impurity intrusion axle bed,
Transmission shaft corrosion is avoided, reduces the maintenance cost of transmission shaft；Closed oiling is realized between transmission shaft and axle bed, wave will not be generated
Take and equipment pollution；It can ensure that transmission shaft rotates freely, operate flexibility and reliability, ensure skidding performance.
Claims (2)
