Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reciprocating driver, and it is simple in structure, compact, not easy to wear, long service life easy to loading and unloading.
The purpose of this utility model can realize by following technical proposal: a kind of reciprocating driver, it is characterized in that, described drive unit comprises motor, the drive being connected with the rotating shaft of motor and the guide pad being connected with the connecting rod of reciprocating pump, on one side end face of described drive, eccentric setting has a bearing, on described guide pad, be provided with a guide groove, described bearing is slidably connected in guide groove and can drives axially reciprocating along connecting rod of guide pad.
In the technical program, because bearing is eccentrically set on the end face of drive, when driven by motor drive rotates, the guide groove inwall of the outer wall of bearing and guide pad leans and slides in guide groove, drives guide pad reciprocating motion simultaneously, the drive mechanism that adopts bearing and guide groove to match, friction less, operating efficiency is high, and wearing and tearing are few, can effectively extend the useful life of whole drive unit, thereby reduce operation and maintenance cost.
In above-mentioned reciprocating driver, on a side end face of described drive, eccentric setting has a joint pin, and described bearing holder (housing, cover) is located on described joint pin.When bearing rotates along with drive, bearing freely rotates in guide groove, and frictional force is less, is conducive to increase the service life.
In above-mentioned reciprocating driver, the top of described joint pin has external screw thread, and the top of described joint pin is connected with nut.Nut can avoid bearing to deviate from rotation process.
In above-mentioned reciprocating driver, the center of described drive has an axis hole, and described rotating shaft is plugged in axis hole and with drive and links together by pin.
In above-mentioned reciprocating driver, described drive unit also comprises a bearing, and described guide pad is slidably connected on bearing.Bearing carries out spacing to guide pad, the direction of motion of guide pad is limited, and guarantees that guide pad can only move along the axial reciprocating of kinematic axis, and can not rotate, and improves stability.
In above-mentioned reciprocating driver, described guide groove and connecting rod axially perpendicular.Guide groove trend is axially perpendicular with connecting rod, makes the force of sliding friction of bearing in guide groove still less, and transmission efficiency is better.
In above-mentioned reciprocating driver, described bearing is rolling bearing.The inner ring of rolling bearing is fixedly connected with joint pin.
In above-mentioned reciprocating driver, described bearing is sliding bearing.Sliding bearing is flexibly connected with joint pin.
Compared with prior art, the drive mechanism that the utility model adopts bearing to match with guide groove, eliminated cross force, cancelled the setting of Compress Spring in cam-type transmission mechanism, avoided as overcoming the consumption of camber of spring energy, greatly improved the efficiency of drive unit, can effectively avoid the wearing and tearing of each parts simultaneously, increased the service life and reduce operation and maintenance cost.

Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Embodiment mono-:
With reference to Fig. 1, the present embodiment is a kind of reciprocating driver, motor 1, the drive 3 being connected with the rotating shaft 1a of motor 1 and the guide pad 5 being connected with the connecting rod 2a of reciprocating pump 2, guide pad 5 is slidably connected on bearing 9 by pole 8, and this pole 8 can axially moving reciprocatingly along connecting rod 2a on the chute 9a of bearing 9.
