A fast detector for radial runout of shaft-connected bearings of water pumps

Abstract

The invention discloses a water pump bearing radial runout rapid detector. The performance test research of an automobile water pump bearing becomes the top priority. The water pump bearing radial runout rapid detector comprises a material feeding mechanism, a material discharging mechanism, a measuring mechanism and a clamp mechanism. The clamp mechanism clamps the water pump bearing on the material feeding mechanism. The measuring mechanism rapidly detects the radial runout of the water pump bearing and transmits the qualified product back to the assembly line, and the rejected product is discharged by the material discharging mechanism. The second stepping motor of the measuring mechanism is fixed on a measuring mechanism support and connected with a first ball screw. A screw pair is formed by a first ball screw cap and the first ball screw. A first screw cap support is fixed on the first ball screw cap. The base of a dial indicator is fixed on the first screw cap support. Two digital display dial indicators are fixed at the two ends of the base of the dial indicator. The measuring heads of the digital display dial indicators orient towards a rotating material feeding part. The radial runout value of the water pump bearing can be rapidly and accurately measured, and the rejected product can be removed out of the assembly line.

Description

technical field [0001] The invention belongs to the technical field of testing, and relates to a bearing detection device, in particular to a fast detection instrument for the radial runout of a shaft-connected bearing of a water pump. Background technique [0002] Water pump shaft bearings are an important part of automotive water pumps. Since the engine, which is the core of the car, is developing towards high power, its calorific value is increasing sharply. The water pump, which is the core component of the cooling system, needs a higher speed and a larger impeller to ensure the normal operating temperature of the engine. At present, the speed of common water pump shaft-connected bearings can reach 6000r / min, and some high-speed shaft-connected bearings can reach 9000r / min. [0003] The radial runout of the water pump shaft-connected bearing is one of the important parameters of the automobile water pump shaft-connected bearing. It will affect the maximum deflection ang...
