Abstract
The utility model relates to a full complement cylindrical roller idler wheel bearing of a coal mining machine. The inner ring of a bearing body is of a shaft (4), the outer ring of the bearing body is of an idler wheel (1), full complement cylindrical rollers (2) are limited between the shaft (4) and the idler wheel (1) and are fully distributed between the idler wheel and a liner, and a baffling ring (3) sleeves the shaft (4) and is located in a groove between the full complement cylindrical rollers (2) and the shaft (4). The full complement cylindrical roller idler wheel bearing has the advantages that since the space between the gear and the supporting shaft is utilized to the utmost extent, the inner ring and outer ring of a conventional bearing are omitted, a standard bearing is replaced with the full complement cylindrical rollers, the rollers actually bearing loads are increased effectively, the service lives of the bearing and idler wheel are prolonged.
Description
Technical field
The utility model relates to the full cylindrical roller idle pulley bearing of a kind of coal winning machine.
Background technique
At present, in existing low seam mining machinery, the application of idle pulley is essential.Idle pulley bears bidirectional load in structure, and the bearing that supports idle pulley is just extremely important.As shown in Figure 1, the bearing of the most employing standards of coal winning machine idle pulley bearing, bearing comprises outer shroud, interior ring and roller, the actual bearing load of bearing be roller, because the load of idle pulley is all very large, to such an extent as to the standard rolling bearing of conventional structure is also very large, but, due to low seam mining machinery structural requirement compactness, limit the size of idle pulley middle (center) bearing, often cannot reach higher working life.In the gear cavity of coal winning machine, often because causing gear, the damage of bearing also damages, and even make the gear of whole Transmitted chains all cause damage in various degree.Want to make the bearing of idle pulley to reach higher working life, usually will sacrifice the univers parameter of coal winning machine, increase length or thickness.In order to meet the univers parameter of low seam mining machinery, improve coal winning machine overall performance, the bearing problem that solves idle pulley just seems particularly important.
Summary of the invention
The purpose of this utility model is: the idle pulley of full cylindrical roller is installed, is utilized to greatest extent the space between gear and back shaft, improve the working life of whole idle pulley group.The technical solution of the utility model is: the full cylindrical roller idle pulley bearing of a kind of coal winning machine, the interior ring of bearing is axle (4), the outer shroud of bearing is idle pulley (1), full cylindrical roller (2) by axle 4 with idle pulley 1 is limited between the two and idle pulley and lining between be booked in order full cylindrical roller (2), baffle ring (3) is sleeved on axle (4) and goes up and be positioned at the groove between full cylindrical roller (2) and axle (4).The beneficial effects of the utility model are: due to the space utilizing to greatest extent between gear and back shaft, cancel interior ring and the outer shroud of conventional bearing, replace the bearing of standard with full cylindrical roller, the roller of actual bearing load is effectively increased, like this, improve the working life of bearing, thereby improved the working life of idle pulley.

Embodiment
As shown in Figure 2, the full cylindrical roller idle pulley bearing of a kind of coal winning machine, the interior ring of bearing is axle 4, the outer shroud of bearing is idle pulley 1, full cylindrical roller 2 by axle 4 and idle pulley 1 is limited between the two and idle pulley and lining between be booked in order full cylindrical roller 2, as shown in Figure 3, baffle ring 3 is sleeved in the groove on axle 4 and between full cylindrical roller 2 and axle 4, baffle ring 3 makes full cylindrical roller 2 not directly and the end contact of axle 4, baffle ring 3 hardness are high, wear resistance is good, improves full cylindrical roller idle pulley bearing working life.
In coal winning machine idle pulley structure, do not use traditional bearing, the spring bearing of idle pulley is replaced to full cylindrical roller 2, the interior ring of bearing is replaced by axle 4, and the outer shroud of bearing is replaced by idle pulley 1.By calculating, obtain external diameter, the diameter of bore of idle pulley 1 and the diameter of full cylindrical roller of axle 4, between idle pulley and axle 4, be booked in order full cylindrical roller 2, ensure that full cylindrical roller can not come off in the time that axle 4 is extracted out, in rotation process, full cylindrical roller can revolve round the sun again in rotation.
Claims (1)
1. the full cylindrical roller idle pulley bearing of coal winning machine, it is characterized in that: the interior ring of bearing is axle (4), the outer shroud of bearing is idle pulley (1), full cylindrical roller (2) by axle (4) with idle pulley (1) is limited between the two and idle pulley and lining between be booked in order full cylindrical roller (2), baffle ring (3) is sleeved on axle (4) and goes up and be positioned at the groove between full cylindrical roller (2) and axle (4).
