在纺织、印染、造纸等机械上,球面轴承应用较广,因而球面加工的好坏,将直接影响设备的精度及使用寿命。对球面轴承的加工,如用常见的旋转法和靠模装置,则很难加工出配合精度高的球面轴承来。后来,我们经过不断的探索,终于制造成球面车削装置.传动原理这台球面车削装置系采用可变双曲柄平行四边形机构,如图1所示:图中 BC 为刀杆,A、D 为机架(即两齿轮的中心),AB、CD 为曲柄(即球面半径 R)。当要车制不同直径的球面时,可以同时改变曲柄 AB与 CD 的长度,但必须使 AB=CD。曲柄旋转由齿条带动,下体2用压板43紧固在车床尾架导轨上(图2中 A-A 剖视)。齿条20、支架25与下拖板1固定在一起,并用原车床刀架固定螺钉
In the textile, printing and dyeing, paper and other machinery, spherical bearings are widely used, so the quality of spherical processing, will directly affect the accuracy and service life of equipment. Spherical bearings on the processing, such as using the common rotation method and by the device, it is difficult to produce a spherical bearing with high precision. Later, after continuous exploration, we finally made a spherical turning device. The principle of transmission This spherical turning device uses a variable double crank parallelogram mechanism, as shown in Figure 1: BC in the picture is the arbor, A and D are the machines Rack (ie two gear center), AB, CD for the crank (ie spherical radius R). When you want to car the sphere of different diameter, you can change the length of the crank AB and CD, but must make AB = CD. The rotation of the crank is driven by the rack, and the lower body 2 is fastened to the lathe tailstock rail by the pressing plate 43 (cross section A-A in FIG. 2). Rack 20, bracket 25 and the lower carriage 1 is fixed together, and the original lathe turret fixed screws
