1 foreword is made in aviation, component of car automobile body is made and measure a domain, often need to offer the bearing of high accuracy to irregular surface, of German KOSTYRKA company flexible bearing unit can offer good solution (graph 1) . Graph 1 those who be used at curved surface bearing is flexible the working principle of 2 locking device is in bearing unit in mechanical system, need countershaft via often can encountering kind the problem that moving link has fixed position locking: If machine tool main shaft or circumgyrate workbench are in the fixed position locking after accurate graduation; The fixed position locking that private plane or the athletic rod that often use in product line sell. German Kostyrka axis kind move a locking device add plastic and sealed wall to give priority to system to be out of shape into high accuracy flexibility with metallic lining go up set. Below the action of liquid pressure, go up cover generation flexibility to be out of shape, be in thereby whole and circumferential on hold firmly need by the moving link of locking. Graph the working principle of 2 locking device pursues the principle that 3 hydraulic pressure assist bearing unit to use locking to cover, the auxiliary bearing that can make independence is unit, use at realizing clamp the auxiliary bearing action when intricate work. Its characteristic is: Incorrect be brought to bear on to cross large active active force by the workpiece of bearing, and only with " counterforce " workpiece of reliable ground bearing, avoided workpiece as a result of the action of bearing force generation to be out of shape thereby. Graph 3 assist bearing unit for Kostyrka standard, go up by crust, fulcrum post and locking a composition, fulcrum post can adjust freely inside certain limits extend length, live to go up by hydraulic pressure locking in bearing after workpiece a locking. The graph extends pattern outside 3 flexibility flexible bearing unit Nextpage pursues 4 be those who introduce drive of guide screw of ball of electric machinery ＋ is flexible bearing is unit, drive lever of bearing of drive of ball guide screw to move up and down through electric machinery, the repetition that bearing lever moves locates precision can amount to M of a few μ . In the graph 2 flexible bearing unit is series connection installation. Graph 4 those who introduce drive of guide screw of ball of electric machinery ＋ is flexible bearing is unit 4 flexible the installation application of bearing unit pursues 5 it is flexible product of bearing unit series of standard, the product in the graph 1 join through end panel flange, connect pressure oil to be able to be used; Product 2 it is flexible bearing unit core, the Kong Zhong that can load an user to abstain is used, flexible of bearing unit core and aperture cooperate to be H7/g6. Graph 5 flexible product of bearing unit series of standard is flexible bearing unit is OK and individual use, many OKer also use jointly. Many flexible when bearing unit is used jointly, can use the combination of product of single series of standard that takes end panel flange, also can abstain poriferous housing, load many flexible bearing unit core makes combination. Graph 6 it is to use poriferous housing, perpendicular place, combination of series connection connective is flexible bearing. Bearing lever introduces drive of only action air cylinder. The graph is 6 poriferous housing, perpendicular place, combination of series connection connective is flexible bearing pursues 7 it is combination flexible an application example of bearing, use at bearing the curved surface workpiece of large, Bao Bi, OK and agile ground is adjusted individually flexible of bearing extend length, in order to get used to the workpiece of different over all dimension. Graph 7 combination are flexible the applied example of bearing CNC Milling
