Description
Technical field
The utility model belongs to a kind of mechanical device, particularly wind energy conversion system driftage self-lubricating device.
Background technique
In large scale wind power machine, the yaw system part that is absolutely necessary, and driftage bearing and the normal lubricated of driftage tooth also are the key factors that guarantees that blower fan runs well in the yaw system; At present; The lubricated of this part all is to be accomplished by motor-drive pump, needs the input ability primer pump of electric energy, needs to consume many electric weight in the using process; In the energy deficient day by day today, can not satisfy energy conservation and environment protection.
And blower fan is guaranteeing under the blower fan normal operation as a kind of device of changing green energy resource, and energy input still less could let blower fan become more green.But the associated description of redgreen blower fan still in the existing technology.
The model utility content
The technical problem that the utility model solved is to provide a kind of wind energy conversion system driftage self-lubricating device of energy-conserving and environment-protective.
The technical solution that realizes the utility model purpose is: a kind of wind energy conversion system driftage self-lubricating device; Comprise driftage speed reducer, base plate, driftage bearing, band eccentric rod gear train, connecting rod, pump piston and lubricant pump cylinder body; The driftage speed reducer that is connected on the said base plate, the gear of driftage speed reducer is meshed with the driftage bearing of floor below, and the drive yaw axis is forwarded moving; The driftage bearing is meshed with band eccentric rod gear train simultaneously; Drive band eccentric rod gear train and rotate, the eccentric rod of band eccentric rod gear train is connected with pump piston through connecting rod, finally drives pump piston to-and-fro motion in the lubricant pump cylinder body.
The utility model compared with prior art, its remarkable advantage is: 1) the utility model will be gone off course the motion of bearing as the driving source of lubricant pump, reduce the energy input of blower fan; And the running and the yawing rotation of pump are formed interlock, and lubricant pump came into operation when lubrication needs was produced, and the minimizing bearing does not operate and lubricates when not required the loss of lubricating grease; 2) principle of the utility model is simple, does not need power source, and energy efficient helps environmental protection.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is the wind energy conversion system driftage self-lubricating device structural drawing of the utility model.
Fig. 2 is the wind energy conversion system driftage self-lubricating device plan view of the utility model.
Fig. 3 is the wind energy conversion system driftage self-lubricating device plan view of the utility model.
Embodiment
In conjunction with Fig. 1, the utility model applies in the MW class wind energy conversion system flank of tooth and bearing lubricated of driftage bearing, in the blower fan driftage, drives pump lubricated to the driftage bearing and the flank of tooth, the selflubricating of the bearing of promptly going off course.
A kind of wind energy conversion system driftage self-lubricating device of the utility model; Comprise driftage speed reducer 1, base plate 2, driftage bearing 3, band eccentric rod gear train 4, connecting rod 5, pump piston 6 and lubricant pump cylinder body 7; The driftage speed reducer 1 that is connected on the said base plate 2, the gear of driftage speed reducer 1 is meshed with the driftage bearing 3 of base plate 2 belows, drives 3 rotations of driftage bearing; Driftage bearing 3 is meshed with band eccentric rod gear train 4 simultaneously; Drive band eccentric rod gear train 4 and rotate, the eccentric rod of band eccentric rod gear train 4 is connected with pump piston 6 through connecting rod 5, finally drives pump piston 6 to-and-fro motion in lubricant pump cylinder body 7.
The lubricant oil in-out apparatus is set on the lubricant pump cylinder body 7, and this device comprises the pipe of two unidirectional foldings, and lubricant oil is through the pipe turnover.
The purpose of the utility model is the flank of tooth of driftage bearing in the MW class wind energy conversion system and bearing lubrication are replaced by the mechanical pump by the rotation drive of driftage bearing with pump by motor-drive pump; The operation that rotational motion through conversion driftage bearing comes driving pump, thus carry out lubricated to the driftage bearing and the flank of tooth.
The utility model is converted into the linear reciprocating motion of lubricant pump through will the go off course rotation of bearing of the gear train of a band eccentric rod, makes to produce pressure in the pump, promotes grease flow to lubricating point.Gear train is forwarded the moving rotating ratio that drives with lubricant pump according to yaw axis and is carried out appropriate design; Motion to the driftage bearing is the disordered motion of clockwise and anticlockwise; The mechanical type lubricant pump should select can positive and negative running plunger pump; And need to design pump according to the lubricated amount of yaw system, control gear can be set in lubricant pump, decide lubricated strategy through master control system.
When wind energy conversion system need be gone off course; Yaw gearbox 1 drives 3 motions of driftage bearing; The gear train 4 that has eccentric rod meshes with driftage bearing 3, and the rotation of driftage bearing 4 is adorned be changed to the eccentric circular movement of eccentric rod, and drivening rod 5 motions; Connecting rod 5 connects pump piston 6; Drive piston 6 and in the stroke of lubricant pump cylinder body 7, do linear reciprocating motion, so just make the lubricating grease in the cylinder body produce the lubricating point that force lubricating grease flow to the driftage bearing and the driftage flank of tooth by the road, the need lubricant housings is lubricated.The utility model forms interlock with the running and the yawing rotation of pump, makes lubricated output and demand form interlock.The driftage bearing movable, lubrication needs produces, and pump brings into operation, thereby carries out lubricated to the driftage bearing and the flank of tooth, forms the effect of driftage bearing selflubricating; When driftage stopped, the driftage bearing stopped lubrication needs, and the operation of pump stops, and lubricated stopping to make the lubricated equilibrium of supply and demand.
