Abstract
The utility model discloses a bevel gear meshing test bench. A large bevel gear and a small bevel gear are respectively installed at one ends of two screw shafts in a mode of close fit, and the screw shafts penetrate into a spacer bush. A regulating nut is respectively installed at each end of the spacer bush on the screw shafts, and the spacer bush is fixedly arranged on a base through a mounted bearing. The other end of the screw shaft provided with the small bevel gear is provided with a hand wheel in the mode of close fit, and the large bevel gear can be meshed with the small bevel gear. The meshing positions of the bevel gears can be changed by changing the positions of the regulating nuts on the screw shafts, and thus the meshing traces of bevel gear pairs under different meshing conditions can be observed. The test bench has the advantages of simple structure and lower manufacture cost and is suitable for widespread use in teaching.
Description
Technical field
The utility model relates to a kind of conical gear engagement experiment table.
Background technology
In mechanical major, the conical gear transmission is one of the rudimentary knowledge that must grasp.Because the singularity of the structure of conical gear, after assembling, all need adjust the relative position of two conical gear, to reach correct meshing relation.Because lack this type of experimental apparatus, the student can not observe the engagement situation of bevel gear pair intuitively, the method for adjustment of indigestion conical gear, especially to " advance greatly from, little go out from; The jacking master, root goes out the master " the adjustment mouth no way understands.
The utility model content
The utility model purpose is to provide a kind of teaching appliance to allow the student grasp by experiment the method for adjustment of bevel gear pair for the defective that prior art exists, and improves results of learning.
For achieving the above object, the utility model adopts following technical scheme:
A kind of conical gear engagement experiment table for teaching, it comprises large bevel gear, cone pinion, 2 screw shafts, 4 rolling bearing units, 4 setting nuts, 2 spacers, handwheel and bases; Described large bevel gear, cone pinion are installed in an end of screw shaft by wringing fit, described screw shaft is through in the spacer, the spacer two ends respectively fill a setting nut, spacer is fixed on the base by bearing and seat, the other end that the screw shaft of cone pinion is housed adopts the wringing fit mode that handwheel is installed, rotate handwheel and can drive the cone pinion rotation, and drive the large bevel gear rotation by cone pinion.
The beneficial effects of the utility model: the student can change the position of conical gear engagement by changing the position of setting nut on screw shaft, observes thus the tooth margin of bevel gear pair in different engagement situations.This experimental apparatus is simple in structure, and manufacturing cost is lower, is fit to teaching and popularizes use.
Description of drawings
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is part decomposition axonometric drawing of the present utility model;
Among the figure: 1-rolling bearing units, 2-screw shaft, 3-setting nut, 4-spacer, 5-large bevel gear, 6-cone pinion, 7-handwheel, 8-base.
Embodiment
As depicted in figs. 1 and 2, a kind of conical gear engagement experiment table for teaching, it comprises that rolling bearing units 1(4 is only), screw shaft 2(2 only), setting nut 3(4 only), spacer 4(2 only), large bevel gear 5, cone pinion 6, handwheel 7, base 8; Described large bevel gear 5, cone pinion 6 are installed in separately screw shaft one end with the wringing fit mode respectively, and are the engagement shape.Described screw shaft 2(2 is only) only be through at spacer 4(2) in, and only respectively fill a setting nut 3(4 at spacer 4 two ends), described spacer 4(2 is only) by rolling bearing units 1(4) be fixed on the base 8.Described handwheel 7 is installed in the other end of the screw shaft 2 that cone pinion 6 is housed by wringing fit.
Rotate handwheel 7 and drive cone pinion 6 rotations, cone pinion 6 drives large bevel gears 5 and rotates.
By changing the position of setting nut 3 on screw shaft 2, change the position of engagement of large bevel gear 5, cone pinion 6, the different meshing relation of bevel gear pair presents different tooth margins thus.
This experiment table has clearly been showed the engagement situation of bevel gear pair, and the student can grasp the method for adjusting the bevel gear pair position of engagement fast by practice, improves learning efficiency.
Claims (1)
1. a conical gear meshes experiment table, it is characterized in that: large bevel gear, cone pinion are installed in respectively an end of two screw shafts by wringing fit, described screw shaft is through in the spacer, respectively fill a setting nut at the two ends of spacer on the described screw shaft, described spacer is fixed on the base by rolling bearing units, the other end that the described screw shaft of described cone pinion is housed adopts the wringing fit mode that handwheel is installed, and described large bevel gear and described cone pinion are engageable.
