Abstract

871,982. Grinding. HEALD MACHINE CO. March 22, 1960 [May 27, 1959], No. 10060/60. Class 60. [Also in Group XXXIV] A high-speed grinding wheelhead comprises a hollow housing 10, a jackshaft 22 which is mounted in the housing and has one end extending from the housing and adapted to receive a pulley 12, and a high-speed shaft 39 which is mounted in the housing parallel to and spaced from the jackshaft and has one end extending from the opposite side of the housing and adapted to receive a grinding wheel 14, the opposite ends of the jackshaft and high speed shaft being connected by a flexible belt. The high-speed shaft is formed with grooves 51, 52 which have circular and conical portions and are engaged by the balls of bearings 37, 38 mounted in a cartridge 13 removable-secured in the housing 10. The shaft, at one end, receives a grinding wheel 14 and.at the other is formed with a pulley 41 which is connected to a pulley 33 on the jackshaft 22 by the belt 42. The jackshaft has a heavy centre portion 23 which serves as a flywheel and at its outer end carries the pulley 12. The belt 42 is tensioned by a pulley 53 carried on an arm 54 urged towards the belt by a spring 58. An extension 56 on the arm engages a piston 59 in a cylinder 61, a spring 64 and fluid in the cylinder providing a dashpot effect. The portion 23 of the jackshaft has recesses 32 which can be engaged by a plunger to hold the jackshaft against rotation when it is desired to remove a nut 81 securing the pulley thereto. Changing the pulley 12 and cartridge 13 varies the speed of rotation of the wheel which may be between 45,000 and 100,000 r.p.m. for grinding the internal bores of the outer races of small ball bearings. The bearings 37, 38 are lubricated by oil mist.
