The utility model relates to an angle adjusting device, and belongs to the field of metallurgical
mechanical equipment. The device body is a sealed box body, the lead screw is rotatably arranged in the box body, and the
trunnion is arranged on the lead screw in a sliding and sleeving mode. The first side face of the
trunnion makes contact with the first side wall of the box body, and an extending block is fixedly arranged on the second side face of the
trunnion, penetrates out of the second side wall of the box body and is connected with an adjusted component. An
oil supply channel is formed in the first side wall of the box body in the length direction of the box body, an oil receiving groove is formed in the first side face of the trunnion, a first
oil distribution channel vertically connected with the
oil supply channel and the oil receiving groove is formed in the
oil supply channel, and an oil guide channel communicated to the contact face of the trunnion and the lead screw is formed in the bottom of the oil receiving groove. Lubricating oil in the oil supply channel flows into the oil receiving groove of the trunnion through the first
oil distribution channel and then flows to the contact face of the trunnion and the lead screw. Independent
oil storage space is provided for each
kinematic pair in the box body, so that the
utilization rate of lubricating oil is improved.
