Abstract
The utility model provides an eccentric gear shaft connecting rod sliding block device for replace the camshaft connecting rod slider device of current piston pump or plunger pump, including 4 parts, 1, eccentric gear shaft and support bearing, 2, connecting rod and connecting rod bearing, 3 crosshad shoe and auxiliary equipment, 4, piston or plunger and jar system. The utility model discloses can replace the camshaft connecting rod slider device of current piston pump or plunger pump, promote piston or plunger and be reciprocating motion, realize the transport of material.
Description
technical field: the utility model relates to the driving power device of reciprocating pump or plunger pump, comprises 4 parts, 1) eccentricity gear axle and spring bearing, 2) connecting rod and connecting rod bearing, 3) crosshead slipper and fixture, 4) piston or plunger and cylinder system.
background technique: reciprocating pump or plunger pump all adopt crankshaft-link rod slide block device at present, major character is the outside that spring bearing is positioned at connecting rod, departing from of connecting rod bearing center line and spring bearing center line is realized by axle bending, wherein bent axle maximizes more difficult, connecting rod bearing is installed more difficult, thus constrains the maximization application of reciprocating pump.
Summary of the invention:
A kind of eccentricity gear axle connecting rod slider device, is in technological scheme: for reciprocating pump or plunger pump, comprises 4 parts, 1) eccentricity gear axle and spring bearing, 2) connecting rod and connecting rod bearing, 3) crosshead slipper and fixture, 4) piston or plunger and cylinder system.
The central axis of described eccentricity gear axle spring bearing is identical with the central axis of gear, not identical with the central axis of connecting rod eccentric shaft, has eccentric position.
The spring bearing of described eccentricity gear axle is positioned at the inner side of connecting rod.
Described eccentricity gear axle spring bearing arranged outside has eccentric shaft, drivening rod and crosshead slipper device can promote piston or plunger does straight reciprocating motion.
The gear pair of described transferring power is positioned at the neutral position, inner side of connecting rod bearing and spring bearing.
The utility model eccentricity gear axle replaces bent axle, and drivening rod slide block device promotes piston and moves reciprocatingly.Eccentricity gear axle intermediate portion is the gear of transferring power, and arrange spring bearing toward both sides, the center line of spring bearing is identical with Gear center line.Eccentric shaft is positioned at the outside of spring bearing mounting point, and its center line and spring bearing depart from certain distance, at eccentric shaft when spring bearing center line rotates, drivening rod and crosshead slipper device can promote piston or plunger does straight reciprocating motion.
Accompanying drawing illustrates:
Fig. 1 is structure front view of the present utility model.
Fig. 2 is structure plan view of the present utility model.
Fig. 3 is structure left view of the present utility model.
Wherein 1 is eccentricity gear axle, and 2 is power input shaft, and 3 is eccentricity gear axle spring bearing, and 4 is connecting rod and connecting rod bearing, and 5 is crosshead slipper device, and 6 is piston or plunger and cylinder system, and 7 is power input shaft spring bearing.
Embodiment
Adopt eccentricity gear axle drive link slide-block mechanism, the crucial curved surface of its eccentricity gear axle major part is all can in the cylndrical surface facilitating position to process, and the difficulty manufacturing processing reduces, and thus more conveniently can realize larger, the power increase transmitted, can overcome the major defect of existing bent axle.The eccentric shaft of eccentricity gear axle and gear shaft integrally, but central axis is not identical, thus can pass through connecting rod slider device driven plunger or plunger reciprocates.
