Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Depend on Figure 1 to Figure 3 As shown, a coupling device with adjustable coaxiality includes a reducer input shaft 6, on which the reducer input shaft 6 is connected with a coupling sleeve 4 through a flat key 5, and the coupling sleeve 4 is set on the reducer input shaft 6 shaft ends, radially fixed by flat key 5. Several steel balls 2 arranged circumferentially are arranged outside the coupling sleeve 4, and the steel balls 2 are supported by the steel ball bracket 3, and the steel ball bracket 3 contacts the steel ball 2 through the spherical surface, so that the steel ball 2 can rotate arbitrarily. The steel ball 2 is covered with a pair of wheel sleeves 1, and the pair of wheel sleeves 1 is connected to the sealing sleeve 7 by bolts 8. The pair of wheel sleeves 1 and the sealing sleeve 7 are all embedded in the motor, and are fixed together with the motor by...

Abstract

The invention discloses a coaxiality-adjustable connecting device. The coaxiality-adjustable connecting device mainly solves the problems that an existing belt connected between a motor of a pumping unit and a speed reducer is laborious to replace and install and prone to causing safety accidents. The coaxiality-adjustable connecting device is characterized in that a shaft coupling sleeve (4) is connected to an input shaft (6) of the speed reducer through a flat key (5); a plurality of steel balls (2) are circumferentially arranged outside the shaft coupling sleeve (4); the steel balls (2) aresupported by a steel ball support (3); a coupling wheel sleeve (1) sleeves the steel balls (2); the coupling wheel sleeve (1) is connected with a sealing sleeve (7) through bolts (8); and the coupling wheel sleeve (1) and the sealing sleeve (7) are embedded inside a motor. The coaxiality-adjustable connecting device is connected with the motor and a speed reducer, a belt transmission mechanism isomitted, the size is small, the structure is simple, the maintenance, disassembly, and assembly are convenient, and the operation is safe and stable.

Description

technical field [0001] The invention relates to the field of oilfield machinery, in particular to a coupling device with adjustable coaxiality. Background technique [0002] The pumping unit is the most common oil production equipment in oil field production. In the pumping unit, the power connection between the motor and the reducer is realized through a belt. In the belt transmission mechanism, the belt is a vulnerable part and needs to be replaced frequently. When replacing the belt, it is necessary to use a crowbar to forcefully pry the belt out of the belt groove on the pulley. At the same time, the pulley is manually rotated, and the old worn belt can be removed by prying repeatedly. The installation of the new belt is also laborious. When the input shaft deforms and protrudes, the pulley will also shake or protrude along with the input shaft, which will easily cause the belt to break or the pulley to fall, and even seriously scrape off the balance weight and cause th...
