The utility model discloses a self-lubricating mould guide sleeve, which relates to the technical field of mould guide sleeve lubrication, aims to solve the technical problems that the abrasion between the guide sleeve and a guide post is increased and the guide sleeve or the guide post is damaged due to insufficient lubrication of the guide sleeve when the current mould guide sleeve runs at a high speed, and comprises the guide post, a spring, a guide sleeve component and a moving component. The spring assists the outer guide sleeve to move, so that the stability and smoothness of the stamping equipment during operation are remarkably improved; linear motion of the outer guide sleeve is converted into rotation motion of the outer sleeve ring and the inner sleeve ring through thread transmission, automatic extrusion and smearing of lubricating oil are achieved in combination with matching of the balls and the sliding grooves, and friction and abrasion between the guide column and related parts are effectively reduced. Meanwhile, the design of the limiting groove avoids waste of lubricating oil and reduces maintenance cost; and the requirement for lubricating the guide pillar in the stamping process is met, the functionality and practicability of equipment are improved, and the service life of the equipment is prolonged.

This invention relates to the field of aero-engine bearing testing technology, and discloses a bearing testing device, including a main shaft, a test bearing assembly, a sealing structure, and a maintenance assembly. The test bearing assembly includes a first bearing housing and a test bearing. The first bearing housing has a first air inlet. The adjusting ring of the maintenance assembly has a first end and a second end. An oil injection ring is spaced apart from the second end to form a sealing channel. A stationary ring is connected to the oil injection ring and positioned close to the second end. The first air bleed channel of the oil injection ring communicates with the second air bleed channel, and the first air bleed channel communicates with the first air inlet. The other end of the second air bleed channel communicates with the sealing channel. This invention, through the spaced arrangement of the rotating and stationary rings and the airflow guidance of the sealing channel, introduces high-temperature gas through the first air inlet of the first bearing housing and guides it into the sealing channel, recreating a real sealing scenario. This makes the bearing test verification more comprehensive and closely resembles the actual working condition, significantly improving the reference value of the test data.
