Problems solved by technology

During the process of placing the slewing bearing on the test device, it needs to be aligned by hoisting, so there is a problem of inconvenient installation. In addition, the value tested by the torque sensor does not directly affect the bearing, but passes through the transmission mechanism such as the reducer. The torque Values ​​are distorted by transmission efficiency

Abstract

The invention discloses a slewing bearing performance testing device. The slewing bearing performance testing device comprises a supporting rack, a slewing driving unit and a planar moving sliding table, wherein the supporting rack is used for bearing the slewing bearing, the slewing driving unit is used for driving an inner ring and an outer ring of the slewing bearing to rotate relatively, and the slewing driving unit is fixed on the plane moving sliding table. During testing, after the slewing bearing is placed on the supporting rack, if the slewing center of the slewing bearing and the slewing center of the slewing driving unit are not coaxial, the plane moving sliding table is started at the moment, and the slewing driving unit is controlled to move in a plane until the central axis of the slewing driving unit coincides with the central axis of the slewing bearing, so that the hoisting difficulty can be reduced, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a performance testing device for a slewing bearing. Background technique [0002] The slewing ring is a large-scale bearing capable of bearing comprehensive loads. It is composed of inner and outer rings, rolling elements, cages, etc., and is widely used in industry. [0003] The starting torque is the torque required for the relative rotation of the inner and outer rings of the turntable. Before installation and application, the starting torque of the slewing ring needs to be measured to measure whether the assembly of the slewing ring is qualified. The measured value of the starting torque measures the steel ball between the inner and outer rings. Whether the size is suitable. If the measured starting torque is greater than the specified starting torque, it indicates that the selection of steel balls is too large and the clearance between the inner and outer rings is...
