Cam sleeve power shaft-driven hollow cam sleeve impact box for implementing method for driving rotation of hollow cam sleeve by cam sleeve power shaft

Abstract

The invention belongs to the field of machinery, and in particular relates to a cam sleeve power shaft-driven hollow cam sleeve impact box for implementing a method for driving rotation of a hollow cam sleeve by a cam sleeve power shaft. The cam sleeve power shaft-driven hollow cam sleeve impact box comprises an impact box, a hollow cam sleeve, hollow cam sleeve bearings, a cam sleeve power shaft,power shaft bearings, connecting rods, guiding components, a power source component, impact heads and the like, wherein a left supporting transmission bearing hole for supporting the cam sleeve powershaft is formed in a left side box plate, and a right supporting transmission bearing hole for supporting the cam sleeve power shaft is formed in a right side box plate; one end of the cam sleeve power shaft runs through the left supporting transmission bearing hole, then is inserted into the hollow cam sleeve, and then is arranged on the power shaft bearing of the right supporting transmission bearing hole; the power source component drives the cam sleeve power shaft to rotate; the cam sleeve power shaft drives the hollow cam sleeve; the hollow cam sleeve drives the connecting rods to move;the connecting rods drive the guiding components and the impact heads to achieve reciprocating impact. The cam sleeve power shaft-driven hollow cam sleeve impact box is simple in structure, does not use easy-shed and quick-wear parts, the service life of the impact box is improved, and the safety and the reliability of equipment are not guaranteed.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a cam sleeve power shaft driving a hollow cam sleeve impact box in which a cam sleeve power shaft drives a hollow cam sleeve to rotate. Background technique [0002] The method for supporting the camshaft in the reciprocating impact box of the existing reciprocating impact mining machine is to set a bearing hole for supporting the camshaft on the left box plate of the box body, and to set a bearing for supporting the other end of the camshaft on the opposite right box plate. , in order to put the camshaft, connecting rod and guide into the impact box, the right side box plate is made into a flap, and the right flap is connected with the impact box with screws, because the right flap and the impact box are The split connection causes an error in the concentricity of the shaft center of the left support camshaft bearing and the right support camshaft bearing, especially under t...

[0002] The method for supporting the camshaft in the reciprocating impact box of the existing reciprocating impact mining machine is to set a bearing hole for supporting the camshaft on the left box plate of the box body, and to set a bearing for supporting the other end of the camshaft on the opposite right box plate. , in order to put the camshaft, connecting rod and guide into the impact box, the right side box plate is made into a flap, and the right flap is connected with the impact box with screws, because the right flap and the impact box are The split connection causes an error in the concentricity of the shaft center of the left support camshaft bearing and the right support camshaft bearing, especially under the strong reciprocating impact vibration, the screws of the right side plate are quickly shaken and loosened, further causing the left There is an error in the concentricity of the shaft center of the side support camshaft bearing and the shaft center of the right side support camshaft bearing, so that the movement direction of the camshaft driving the connecting rod is different from the impact direction of the impact head guided by the guide, causing the camshaft to be connected. The rod damages the impact head of the guide part and has a complex structure and many wearing parts, which damages the guide system and the camshaft transmission system; and because the flap on the right side is shaken loose, the lubricating and cooling liquid in the impact box flows from the box plate on the right side. The outflow of the gap between the impact box and the impact box leads to overheating and locking of the bearing in the impact box, which makes the reciprocating impact system scrapped and causes huge losses such as shutdown and production.
