Abstract

The utility model relates to a four-row cylindrical roller bearing assembly for a novel diaphragm pump and belongs to the bearing manufacturing industry of the field of machining. The four-row cylindrical roller bearing assembly adopts rolling bearings to replace small-head tiles; with the adoption of an integrated structure of an outer ring, the rigidity of the complete assembly is effectively ensured, the stress concentration at the contact is avoided, and the damage due to impact load is prevented; by adopting an oil hole on an excircle of the outer ring and an oil line inside a piston pin, the lubricating effect of the assembly can be improved; and with the addition of a metal sealing ring embedded in the end surface of the outer ring, the oil storage and the lubrication are more effectively completed. Therefore, the four-row cylindrical roller bearing assembly has compact structure and perfect performance, reasonably controls the clearance and is reliable to run.

Description

A kind of new types of diaphragm pump is assembled with four-line column roller bearing

Technical field

The utility model relates to a kind of new types of diaphragm pump to be assembled with four-line column roller bearing, belongs to the bearing manufacturing of field of machining.

Background technique

Usually the structure that adopts of connecting rod small end place links to each other with wrist pin (or crosshead pin) for microcephaly's one end is equipped with microcephaly's watt (copper sheathing), but requirement has the very thin oil film lubricate of one deck between microcephaly watt and the wrist pin.If because insufficient lubrication, just have directly friction between bearing shell and the wrist pin, friction can produce very high temperature, adds top bearing shell and also may factor cause tile kilning because load is excessive, there is impurity in lubricant oil or viscosity is unusual etc., cause to-and-fro motion to be lost efficacy, influence the equipment proper functioning.

Because the connecting rod small end place is comparatively strict to lubricating requirement, so connecting rod small end watt required lubricant oil, number average watt is located to attract from connnecting rod big end mostly, so often be drilled with oilhole in the shaft; Also useful attached oil pipe is close to the structure of shaft one side simultaneously, now less application, but the effect of the lubrication effect of said method, control play is all not good.

Summary of the invention

In view of the defective that prior art exists, the purpose of this utility model is to provide a kind of new types of diaphragm pump to assemble with four-line column roller bearing, and this structure is to replace microcephaly watt with rolling bearing, has compact structure, advantages such as perfect performance is rationally controlled play, and equipment operation is reliable.

For achieving the above object, the technical solution that the utility model adopted:

A kind of new types of diaphragm pump is assembled with four-line column roller bearing, be made up of wrist pin, seal ring, outer ring and roller, it is characterized in that: the outer ring is one four row raceway structures, completely adorns roller in the raceway and does not have retainer, cycle surface embeds metallic packing ring, and wrist pin inside is provided with oily line.

Described outer ring outer round surface is provided with the snap ring groove with the microcephaly location.

After adopting such scheme, compare with existing bearing and the utlity model has following beneficial effect:

The utility model is to replace microcephaly watt with rolling bearing, and the outer ring integrative-structure guarantees the kit rigidity effectively, has avoided contacting point stress to concentrate, and prevents the destruction that impulsive load is brought; By the oilhole of outer ring cylindrical and the oily line of wrist pin inside, can improve its lubrication effect, add the metallic packing ring that cycle surface embeds, more effectively finish oil storage, lubricated.So the utility model compact structure, perfect performance is rationally controlled play, and equipment operation is reliable.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure: 1, wrist pin, 2, seal ring, 3, the outer ring, 4, roller, 5, snap ring groove.

Embodiment

Concrete scheme of the present utility model is as follows:

As shown in Figure 1, a kind of new types of diaphragm pump is assembled with four-line column roller bearing, form by wrist pin 1, seal ring 2, outer ring 3 and roller 4, it is characterized in that: outer ring 3 is one four row raceway structures, completely adorn roller 4 in the raceway and do not have retainer, outer ring 3 end faces embed metallic packing ring 2, the snap ring groove 5 of outer ring 3 outer round surface settings and microcephaly location, and wrist pin 1 inside is provided with oily line.

Outer ring 3 integrative-structures guarantee the kit rigidity effectively, are adding man-hour, the reconditioning rib, make the rib that contacts with roller 4 that certain inclination be arranged, roller 4 cylindrical buses are done logarithm or circular arc correction, avoided contacting point stress to concentrate, prevent the destruction that impulsive load is brought; Outer ring 3 outer round surface provide the snap ring groove 5 with the microcephaly location; Completely adorning roller 4 causes the bearing capacity of kit to improve; Because the lubricating system of linkage mechanism is a splash lubrication, by the oilhole of outer ring 3 cylindricals and the oily line of wrist pin 1 inside, can improve its lubrication effect, add the metallic packing ring 2 that outer ring 3 end faces embed, more effectively finish oil storage, lubricated.

The utility model compact structure, perfect performance is rationally controlled play, and equipment operation is reliable.
