Spindle sleeve

For filling, the spindle sleeve is pneumatically retracted, and the compressed air for the venturi nozzle is turned on. A vacuum is applied to the filling injector and the material hose. This vacuum sucks the foam particles out of the filling container. 

The main spindle of the lathe with a center distance of 550 mm was disassembled and then reassembled with adhesives. In the conventional construction, the main spindle, bearings, and spindle sleeves are assembled into a spindle unit, and this is pressed into the spindle box. When using adhesives in the assembly, the outer diameters of the sleeves were reduced to make gaps of 200 jum, and then the gaps were filled with the adhesive. 

Fit ball bearing DA5 (see below upper buffer DA7 spacing sleeve DA6, and ball bearing DAB in the ball bearing housing. Screw on lock ring DA9. Heat the unit in oil to 160-180°F (70-80°C) and push it on the spindle. 

Spinhaler uses two perforating pins to puncture the capsule body for opening. To feed the capsule, the patient has to unscrew the device body and push the capsule into a cup that is connected with a vertical spindle holding a propeller. After closing, the capsule is pierced by sliding the outer sleeve down and back again. When the patient tilts his or her... 

For manual tool change only the Morse taper according to ISO 296 is used (Fig. 1) on shop floors in some cases. The force and torque transfer is achieved via the frictional contact of a self-locking taper angle of 1 20. For higher loads there are models with a clamp thread or a cotter. This type of interface is used in drilling spindles and sleeves of tailstocks. 

The edge of the thimble is graduated in 50 divisions numbered 0, 5, 10, up to 45, then 0. Since one revolution of the thimble advances the spindle 0.5 mm, one graduation on the thimble must equal 0.5 50 mm = 0.01mm. A reading is therefore the number of 1 mm and 0.5 mm divisions on the sleeve uncovered by the thimble plus the hundredths of a millimetre indicated by the line on the thimble coinciding with the longitudinal line on the sleeve. 

Where a cutting tool or chuck has a Morse taper smaller than that of the spindle, the difference is made up by using a sleeve. For example, a drill with a No. 1 Morse-taper shank to be fitted in a spindle with a No. 2 Morse taper would require a 1-2 sleeve, i.e. No. 1 Morse-taper bore and a No. 2 Morse taper outside. Sleeves are available from 1-2, 1-3, 2-3, 2-4 and so on over the complete range. 

Dimensions of the adhesive area were 162 mm and 160 mm for the diameters of the chuck and the driving sides, respectively, and 42 mm in width. Grooves 50 pm deep and 15 mm wide were also prepared between the sleeves and the bearings, to be filled with the adhesive for joining the latter together. In Fig. 5.22 are shown the lathe spindles assembled in... 

The lathe spindle was assembled in the following manner with the adhesive. The bearings were first installed on the spindle and the sleeves bonded. The spindle nut was then tightened to apply appropriate pressure on the bearings. Then the whole spindle unit was inserted into the spindle box with the adhesive on its sleeves. The spindle location was adjusted during the pot-life of the adhesive, so that assembly errors in the parallelism between the spindle and the carriage motion, and difference between the heights of the head and tail stocl, were reduced to tolerable levels.
