Description
Technical field
The utility model relates to transmission device field, is specifically related to a kind of bearing unit of output shaft of speed reducer.
Background technique
As shown in Figure 1, the bearing support of the output shaft of existing speed reducer is fixedly connected with the housing of speed reducer, bearing support is provided with the through hole of the output shaft for passing speed reducer, this through hole is disposed with the first step portion of mounting flange from outside to inside, 3rd stepped part of bearings mounted second step portion and installation jump ring, first step portion, second step portion and the 3rd stepped part are coaxially arranged, the diameter of the 3rd stepped part is greater than the diameter in second step portion, the diameter in second step portion is greater than the diameter in first step portion, during installation, need from the first mounting flange of bearing support Inside To Outside, then bearing is installed, and then jump ring is installed, by jump ring by flange plate and bearing clamping.The shortcoming of the bearing support of this structure is: bearing support adds man-hour cannot be shaping with bearing housing clamped one time turnery processing, because the through hole of bearing support decreasing pore size from outside to inside, so bearing support needs from the independent turnery processing of Inside To Outside, therefore, process very loaded down with trivial details because bearing support will with the housing separate machined of speed reducer, even if so the precision of processing can meet standard, when bearing support assembles, also can produce certain error, affect the precision of bearing support.When assembling, the flange of existing speed reducer output shaft, bearing and jump ring need from inside to outside to assemble successively, and the precision of assembling cannot ensure, and assembling is inconvenient.
Summary of the invention
The purpose of this utility model is that the bearing unit processing of the output shaft for existing speed reducer pointed in background technique is loaded down with trivial details, work efficiency is low, be inconvenient to assemble, the problem that assembly precision cannot ensure, a kind of bearing unit that can solve the output shaft of the speed reducer of foregoing problems is provided.
The technological scheme realizing goal of the invention of the present utility model is as follows:
A kind of bearing unit of output shaft of speed reducer, it comprises bearing support, bearing, flange plate and jump ring, described bearing support is provided with the through hole of the output shaft for passing speed reducer, bearing positioning table terrace is provided with in through hole, the inner side end of the outer ring of bearing withstands on bearing positioning table terrace, the arranged outside being positioned at bearing positioning table terrace in through hole has jump-ring slot, jump-ring slot is positioned at the outside of the end face outside of bearing, carry out axial limiting by jump ring to bearing, the outside of jump-ring slot is the cylindrical hole of assembly flange dish.
For the ease of the assembling of bearing support, the left and right sides of described bearing support is provided with pilot hole.
The beneficial effects of the utility model are: the bearing block structure of the bearing unit of the output shaft of speed reducer of the present utility model is simple, easy to process, adding man-hour, bearing support blank directly can be fixed on the shell of speed reducer, be fixed on the output shaft position of speed reducer, then the end face in hole being processed externally in the hole of bearing support of speed reducer, disposablely can complete bearing positioning table terrace, the processing of the cylindrical hole of jump-ring slot and assembly flange dish, and because be bearing support is contained in speed reducer shell on process, so the precision in the face of processing is higher.In addition, when assembling, can directly bearing, jump ring and flange plate be loaded successively in the through hole of bearing support from the outside of speed reducer, the precision of assembling is higher, assembles more convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bearing unit of the output shaft of existing speed reducer;
Fig. 2 is the structural representation after the bearing unit of the output shaft of speed reducer of the present utility model and box body of speed reducer assemble;
Fig. 3 is the structural representation of bearing support of the present utility model;
In figure, 1 is bearing support, and 2 is bearing, and 3 is flange plate, and 4 is jump ring, and 5 is bearing positioning table terrace, and 6 is jump-ring slot, and 7 is cylindrical hole, and 8 is the housing of speed reducer, and 9 is output shaft, and 10 is pilot hole.
Embodiment
With reference to the bearing unit of the output shaft of a kind of speed reducer shown in Fig. 2 to Fig. 3, it comprises bearing support 1, bearing 2, flange plate 3 and jump ring 4, described bearing support 1 is provided with the through hole of the output shaft 9 for passing speed reducer, bearing positioning table terrace 5 is provided with in through hole, the inner side end of the outer ring of bearing 2 withstands on bearing positioning table terrace 5, the arranged outside being positioned at bearing positioning table terrace 5 in through hole has jump-ring slot 6, jump-ring slot 6 is positioned at the outside of the end face outside of bearing 2, axial limiting is carried out by jump ring 4 pairs of bearings 2, the outside of jump-ring slot 6 is the cylindrical hole 7 of assembly flange dish 3.
For the ease of the assembling of bearing support, the left and right sides of described bearing support is provided with pilot hole 10.
The bearing unit of the output shaft of a kind of speed reducer of the present utility model, adding man-hour, first the blank of bearing support is fixed on the housing 8 of speed reducer by bolt or screw, then by relevant cutter, the cylindrical hole of the through hole in bearing support, bearing positioning table terrace, jump-ring slot, assembly flange dish is processed.Because bearing support can with reducer shell clamped one time, once complete course of working, so work efficiency is high.Because be the assembling of advanced bearing support, then process, so the precision of processing is higher, the error that bearing support assembling produces can be overcome.When assembling, after assembling output shaft 9, running in bearings, jump ring and flange plate successively from outside to inside, because be assemble from outside to inside, compared with the mode must from inside to outside assembled with existing bearing support, assemble simple and convenient, and the precision of assembling easily controls, and assemble and dismantle all very convenient.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technological scheme, therefore all equivalent technological schemes all should be included into scope of patent protection of the present utility model.
