Abstract

The invention relates to a bearing of a concrete mixer. The bearing comprises a race, an upper shaft washer, a lower shaft washer and cylindrical rolling bodies, wherein the race is provided with two upper raceways, two lower raceways and a side raceway; the cylindrical rolling bodies are placed in the upper raceways, the lower raceways and the side raceway; the bearing is innovatively characterized by comprising an upper main flow channel and a lower main flow channel, the upper main flow channel and the lower main flow channel are respectively communicated with two upper branch flow channels and two lower branch flow channels, which extend to the upper raceways and the lower raceways; a lubricating nipple component used for supplying oil to the upper main flow channel and the lower flow channel is arranged on the race, and comprises a lubricating nipple mounting seat and a movable oil nipple capable of rotating in the lubricating nipple mounting seat; the movable oil nipple adopts the structure with a single oil inlet and double outlets; the double outlets are corresponding to the upper main flow channel and the lower main flow channel in the axial direction, and are arranged in a staggered manner in the radial direction. The upper main flow channel are matched with the two upper branch flow channels so as to supply oil to the upper raceways, and the lower main flow channel and the two lower branch flow channels are used for supplying oil for the lower raceways and the side raceway; the two main flow channels use one oil nipple, when oiling is required, oiling paths can be changed through rotating the oil nipple; the bearing is compact in structure, and reduces the using numbers of lubricating nipples, so that the cost is reduced.

Description

A kind of concrete mixer axis holds

Technical field

The present invention relates to a kind of bearing, particularly a kind of concrete mixer axis holds.

Background technique

Excavator is to excavate higher or lower than the material that holds machine side with scraper bowl, and the haulage vehicle or unload the earth moving machinery to stocking yard of packing into.The material that excavator excavates is mainly soil, coal, silt and the Soil and Rock after pre-pine.From the development of engineering machinery in recent years, the development of excavator is relatively very fast, and excavator has become one of topmost engineering machinery in engineering construction.

The digger revolving supporting is the novel mechanical component that worldwide rose gradually in nearly 40 years, in engineering machinery, be widely used, it has the formations such as Internal and external cycle, rolling element, along with developing rapidly of engineering machinery, its various performances, functional requirement to bearing is also more and more higher, and the large carrier bearing of various many raceways is given birth to thereupon, for different bearing structures, its lubricating structure is also different, does not find the digger revolving supporting lubricating structure identical with the present invention through retrieval.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of concrete mixer axis easy to lubricate and holds.

For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of concrete mixer axis holds, and comprises seat ring, upper blowout patche, lower blowout patche and cylinder rolling element, on seat ring, evenly is drilled with the seat ring mounting hole that distributes ringwise and connect the upper and lower end face of seat ring; Upper and lower blowout patche is the ladder tubular structure with large and small end, between upper blowout patche and seat ring, forms raceway on twice, between lower blowout patche and seat ring, forms raceway under twice, between the outer side surface of seat ring side and upper and lower blowout patche, forms one and sidewinders; Described upper and lower, place the cylinder rolling element in sidewindering; Its innovative point is: comprise the horizontally disposed upper sprue of twice and lower sprue, upper sprue radially extends to the seat ring middle part from the outer side surface of seat ring along seat ring, upper sprue is communicated with two upper branch flow passages, and these two upper branch flow passages extend to the bottom of raceway vertically upward; Lower sprue radially extends to sidewindering of seat ring inner side surface from the outer side surface of seat ring along seat ring; Lower sprue is communicated with two lower branch flow passages, and these two lower branch flow passages extend to the top of lower raceway vertically downward; The upper-end surface of seat ring has a cavity, the built-in nozzle component to upper and lower sprue fuel feeding of cavity, this nozzle component comprises an oil nozzle fitting seat and the movable fuel filler neck that can rotate in the oil nozzle fitting seat, movable fuel filler neck is one and has the structure of singly advancing two oil outlets, two oil outlets are corresponding with upper and lower sprue respectively in the axial direction, the setting of staggering diametrically of two oil outlets; Outermost end seal with screwed joint plug at upper and lower sprue.

The invention has the advantages that: by upper sprue, with branch flow passage on two, coordinate upper raceway fuel feeding, lower sprue and twice branch flow passages are to lower raceway and sidewinder fuel feeding; Two sprues share a fuel filler neck, by the rotation fuel filler neck, change the oiling path in the time of need to refueling, and simplify structure, reduce the use amount of oil nozzle, reduce costs.

Embodiment

As shown in Figure 1, comprise seat ring 1, upper blowout patche 2, lower blowout patche 3 and cylinder rolling element.

On seat ring 1, evenly be drilled with the seat ring mounting hole 4 that distributes ringwise and connect seat ring 1 upper and lower end face.

Upper blowout patche 2, lower blowout patche 3 are the ladder tubular structure with large and small end, and upper blowout patche 2 and lower blowout patche 3 are bolted and form an I shape.Between upper blowout patche 2 and seat ring 1, forming raceway on twice, between lower blowout patche 3 and seat ring 1, forming raceway under twice, between the outer side surface of seat ring 1 side and upper blowout patche 2, lower blowout patche 3, forming one and sidewinder; And upper and lower, place the cylinder rolling element in sidewindering.

Comprise the horizontally disposed upper sprue 5 of twice and lower sprue 6, for meeting the processing technology requirement, upper sprue 5 radially extends to seat ring 1 middle part from the outer side surface of seat ring 1 along seat ring 1, upper sprue 5 is communicated with two upper branch flow passages 7, and these two upper branch flow passages 7 extend to the bottom of raceway vertically upward. and lower sprue 6 radially extends to sidewindering of seat ring 1 inner side surface from the outer side surface of seat ring 1 along seat ring 1.Lower sprue 6 is communicated with two lower branch flow passages 8, and these two lower branch flow passages 8 extend to the top of lower raceway vertically downward.
