Abstract
The utility model discloses a hoisting tackle single-hole multi-oil-way lubricating device, which comprises a pulley shaft and two mandrels. The pulley shaft is provided with an inner hole; the two mandrels are symmetrically sleeved inside the inner hole of the pulley shaft; lubricating oil grooves are arranged on the peripheral walls of the two mandrels; the number of the lubricating oil grooves is the same with that of lubricating points; oil cup holes respectively communicated with the lubricating oil grooves are arranged at the ends of all the mandrels; oil cups are mounted inside the oil cup holes; oil holes for communicating the lubricating oil grooves on the mandrels with the lubricating points corresponding to the lubricating oil grooves are arranged on the pulley shaft; and the pulley shaft is fixed with the mandrels by the aid of edge junction screws. The hoisting tackle single-hole multi-oil-way lubricating device not only ensures that each lubricating point is provided with an independent lubricating oil way and an independent lubricating oil cup, adds oil in a point-to-point manner and guarantees optimal lubricating state of bearings, but also decreases the number of processing long and thin holes on the lubricating shaft and reduces processing difficulty and the labor intensity of workers, and has the advantages of compact and reasonable structure, high work efficiency and simple and convenient maintenance.
Description
Technical field
The utility model relates to a kind of lubricating fitting of lifting tackle.
Background technique
The lubricating fitting of lifting tackle is the mechanism that guarantees that coaster runs well.Existing lubricating fitting majority is following two kinds of forms: a kind of is to give each lubricating point processing an elongated hole in pulley spindle, as independent lubricating oil path, opens many cylindrical voids in axle, and difficulty of processing is big, labor strength height, cost height; Second kind is to process an elongated hole as public oil circuit in pulley spindle, the groove that lubricating point is led in reprocessing removes to connect a plurality of lubricating points, though this kind mode difficulty of processing reduces, lubricant oil flows to the lubricating point near lubricating cup mostly, and is not good away from the lubricating point lubrication effect of lubricating cup.
Summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provide a kind of each lubricating point that can guarantee that an independent lubricating oil path is all arranged, can reduce the quantity in processing slim hole in lubricated axle again, reduce the lifting tackle single hole heavy wool road lubricating fitting of difficulty of processing and labor strength.
For addressing the above problem, technical solution of the present utility model is: a kind of lifting tackle single hole heavy wool road lubricating fitting, and it comprises that pulley spindle and symmetry are installed in two core bars in the pulley spindle, pulley spindle has endoporus, pulley spindle external diameter and bearing inner race are complementary, and its endoporus and core bar are complementary; Two core bar symmetries are sleeved in the endoporus of pulley spindle, have the oil groove identical with the number of lubricating point on two core bar walls, and the end of each core bar all has the lubricating cup hole that is connected with oil groove respectively, and lubricating cup is installed in the lubricating cup hole; Have on the pulley spindle oil groove on the core bar and the oilhole that is connected with the corresponding lubricating point of oil groove, pulley spindle and core bar are fixed by junction of the edges of two sheets of paper screw.
Above-mentioned described two core bars and pulley spindle endoporus interference fit.
The utility model is compared with past lifting tackle lubricating fitting, only process an endoporus on the lubricated axle, a plurality of oil grooves are opened on two core bars, guaranteed that not only each lubricating point all has an independent lubricating oil path, independent lubrication ring, point-to-point oiling guarantees that the bearing lubrication state is in the best; And reduced lubricated axle and gone up the quantity in processing slim hole, reduced difficulty of processing and labor strength.Core bar is by junction of the edges of two sheets of paper screw, and is obstructed as oil circuit, lays down junction of the edges of two sheets of paper screw and can pull down the core bar inspection, keeps in repair easy.The utility model compact structure, rationally, high working efficiency.

Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is further described:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, present embodiment comprises that pulley spindle 1 and symmetry are installed in two core bars 2 in the pulley spindle 1.Pulley spindle 1 has endoporus 10, and pulley spindle 1 external diameter and bearing 5 inner rings are complementary, and its endoporus and core bar 2 are complementary.Two core bar 2 symmetries are sleeved in the endoporus 10 of pulley spindle 1, core bar 2 and pulley spindle 1 endoporus interference fit, have four oil grooves 7,8,15,16 on each core bar 2 wall, its end has the screw thread lubricating cup hole 11,12,13,14 that is connected with four oil grooves 7,8,15,16, and lubricating cup 3 screw threads are installed in the lubricating cup hole 11,12,13,14.Have on the pulley spindle 1 oil groove on the core bar 7,8,15,16 and the oilhole 9 that is connected with the corresponding lubricating point of oil groove, pulley spindle 1 is fixing by junction of the edges of two sheets of paper screw 4 with core bar 2.6 is pulley.
Certainly; the utility model also has other various embodiments; under the situation of the utility model spirit and essence; those of ordinary skill in the art can make corresponding change and distortion according to the utility model; but these corresponding changes and distortion all should belong to the improvement of equivalent technologies, belong to the protection domain of the utility model claim.
