Abstract

The invention discloses a bearing clearance measuring machine which comprises a machine body. An operation panel is arranged at the upper end of the front surface of the machine body, a working tableis arranged at the top of the machine body, a sliding groove is formed in the working table, a measuring base is arranged in the sliding groove in a sliding mode, and a limiting column is fixed to theportion, at the outer end of the sliding groove, of the working table. A rack is fixed to the top of the working table, an air cylinder is vertically fixed to the top of the rack, a piston rod in theair cylinder is fixedly connected with one end of a connecting rod, and the other end of the connecting rod is fixedly connected with a balance weight load. By arranging a clamping wheel, a clampingwheel frame body, a lead screw nut, an upper lead screw, a lower lead screw, a double-end clamping motor, a guide column and a grating ruler, automatic centering can be achieved during bearing clamping, positioning is accurate, a symmetrical structure is adopted for driving and loading, the influence of an unbalance loading force on clearance measurement is removed, measurement is performed through the grating ruler, and a measurement result of the whole measurement machine is more accurate.

Description

technical field [0001] The invention relates to the technical field of bearing production equipment, in particular to a bearing clearance measuring machine. Background technique [0002] Bearing clearance refers to the amount of movement when the bearing is not installed on the shaft or bearing box, the inner ring or the outer ring is fixed, and then the unfixed side moves radially or axially. According to the moving direction, it can be It is divided into radial clearance and axial clearance. The size of the clearance during operation has an impact on the rolling fatigue life, temperature rise, noise, vibration and other performance of the bearing. When the bearing clearance is too small, the most likely situation is The bearing is hot, and if the speed is faster, it may burn out, and if it continues to operate at high temperature and high speed for a long time without paying attention, it is very likely that the bearing will lock up and cause damage to the bearing. The su...
