Abstract

The utility model discloses an oil bearing lubricating device for vertical mechanical axis, which is characterized in that: a thrower (5) is fixed and matched to a principal axis (3) and its lower end is extended into a oil pond (9) of a bearing box (1) and is fixed on the principal axis by a flat key (4) and a locknut (8); lower part of the bearing box is provided with an oil deflector (7) coaxial with the principal axis; upper part of the oil deflector is extended into the thrower and the two matched with each other crosswise in the oil pond. The utility model, with simple structure and solving of the easy leakage of the traditional vertical mechanical axis sealing structure during the operation of the oil lubrication, is applicable for the lubricating and sealing of various vertical mechanical axes.

Description

Vertical drive shaft thin oil bearing-lubricating device

Technical field

The utility model belongs to the pumping unit technical field, is specifically related to a kind of vertical drive shaft thin oil bearing-lubricating device that is suitable for vertical rotary mechanism.

Background technique

Under some high temperature (temperature 120-350 ℃) operating conditions, vertical rotary mechanism bearing usually needs thin oil lubricant, can not adopt grease lubrication, but the problem that common vertical rotary mechanism bearing adopts thin oil lubricant to exist lubricant oil to leak vertically not only causes waste but also befouling environment, for this reason, the design people is through concentrating on studies, developed a kind of vertical drive shaft thin oil bearing-lubricating device, evidence, effect is good.

The model utility content

1, the technical problem that will solve

It is a kind of simple in structure that the purpose of this utility model is to provide, the vertical drive shaft thin oil bearing-lubricating device that processing and fabricating is easy.

2, technological scheme

The utility model is achieved in that and comprises disc, flinger ring, disc and main shaft secure fit, the disc lower end is stretched in the oil sump of bearing housing, and is fixed on the main shaft by flat key, locking nut.Fixedly install the flinger ring coaxial with main shaft in the bearing housing bottom, flinger ring top is inserted into the inboard of disc, and both intersections are actively tied in the oil sump; Vertical oil guiding hole is set in the ring wall of disc, and the oil guiding hole lower end communicates with oil sump, and the oil guiding hole upper end open is positioned at the outer rim of disc convex shoulder, the top of bearing stationary ring.

3, beneficial effect

The utility model adopts disc to cooperate the flinger ring structure, has avoided the thin oil leakage problems effectively, has improved the effect of thin oil lubricant simultaneously, has not only avoided the pollution of working environment, and energy-saving and cost-reducing, has improved economic benefit.

Embodiment

Shown in Fig. 1-2, the utility model comprises disc 5, flinger ring 7, disc 5 and main shaft 3 secure fit, and disc 5 lower ends are stretched in the oil sump 9 of bearing housing 1, and are fixed on the main shaft 3 by flat key 4, locking nut 8; Fixedly install the flinger ring 7 coaxial with main shaft 3 in bearing housing 1 bottom, flinger ring 7 tops are inserted into the inboard of disc 5, and both intersections are actively tied in the oil sump 9; Vertical oil guiding hole 6 is set in the ring wall of disc 7.

Fig. 3-4 shows the overall structure of disc.Described disc 7 is for upper limb has convex shoulder, and the middle part is provided with outside thread, the ring structure that inwardly closes up in the bottom, vertical oil guiding hole 6 is set in the ring wall of disc 7, oil guiding hole 6 upper end open are positioned at the convex shoulder cylindrical, the top of bearing 2 inner rings, and oil guiding hole 6 lower ends are communicated with oil sump 9.This structure helps lubricant oil guide bearing ball part, strengthens lubrication effect.

The quantity of oil guiding hole 6 is 2-6 on the described disc 5, decides according to the girth of ring, and girth is long more, and quantity can be some more, otherwise can be less.As a kind of mode of execution, be provided with 3 oil guiding holes 6 among the figure.

Fig. 5-6 shows the structural relation of flinger ring and bearing housing.The outside, described flinger ring 7 lower ends and bearing housing 1 bottom spindle hole secure fit, flinger ring 7 tops are inserted into the inboard of disc 5, and both intersections reach the purpose of thin oil seal movingly, prevent that lubricant oil is excessive.

Working principle of the present utility model and working procedure: disc 5 and main shaft 3 be by flat key, locking nut 8 stationary fits, and with the bearing inner race stationary fit.Bearing 2 lubricated be by being arranged at the oil guiding hole on disc 5 ring walls, and lubricant oil guide bearing from oil sump 9 is brought in realization.Flinger ring 7 plays the labyrinth buffer action, prevents that further lubricant oil is excessive excessive by the oil guiding hole on the disc, thereby avoids leakage pollution.

The utility model not only has simple in structure, the reliable characteristics of working stability, and thin oil lubricant Effectively improve the motion of main shaft operating mode, increase work efficiency; Overcome simultaneously under rare oil lubrication operating mode, The problem that the conventional seals structure is leaked easily. The utility model is applicable to that various vertical mechanical axles are lubricated and close Envelope has stronger application value.
