Abstract
The utility model relates to a bottom guide wheel of a platform truck, which comprises a bracket (1), a roller wheel (2) and a shaft (7). The roller wheel (2) is arranged below the bracket (1) and is connected with the bracket (1) through the shaft (7). The bottom guide wheel of the platform truck is characterized in that an annular convex belt (2.1) is arranged on the roller wheel (2); the roller wheel (2) is connected with the shaft (7) through a bearing (4); a bearing end cover (3) is arranged outside the bearing (4); a gasket (5) is sheathed on the shaft (7) at the clearance position between the two ends of the roller wheel (2) and the bracket (1); and a bushing (6) is arranged at the connecting part between the shaft (7) and the bracket (1). The roller wheel of the bottom guide wheel is provided with the annular convex belt, and the annular convex belt plays the role of guiding and cannot slide off a track; the shaft and the roller wheel are connected by the bearing, the contact area is small and the friction coefficient is low, so that the burden of a blunt-tooth mechanism is reduced; moreover, the bottom guide wheel of the platform truck cannot be easily damaged, has long service life and good overall stability, cannot easily swing and cannot destroy the track.
Description
(1) technical field
The utility model relates to a kind of platform truck guiding return pulley, is mainly used in forging or other high temperature and leads with heating furnace or drawing furnace platform truck return pulley.Belong to the forging equipment technical field.
(2) background technology
Forge or other high temperature are provided with track with quadrate part under heating furnace or the drawing furnace platform truck, the platform bus equipment has roller, and roller directly rolls in orbit during operation, thereby drives advancing or retreating of platform truck.The mounting means of existing roller is to adopt center shaft to pass the roller inwall to be directly installed on the platform truck bottom, center shaft and roller internal face area of contact are big, friction coefficient is big, and cognate mechanism needs bigger power platform truck could be advanced in the stove, increases the burden of cognate mechanism; And because friction force is big, under the long term high temperature situation the damaged cycle of equipment very short, need often maintenance, when increasing maintenance cost, reduced work efficiency; In addition,, cause whole platform truck stability bad, wave the havoc track owing to have the gap between center shaft and the roller inwall.And existing roller does not have directional tagging, and there is potential safety hazard in slippage from the track easily.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide that a kind of friction coefficient is little, not fragile, long service life, stability are high, can be from the platform truck guiding return pulley of slippage on the track.
The purpose of this utility model is achieved in that a kind of platform truck guiding return pulley, comprise support, roller and axle, described roller is positioned at the support below, and by the axle be connected with support, it is characterized in that: the protruding band of ring-type is set on the described roller, and described roller is connected with axle by bearing, and described bearing is outside equipped with roller bearing end cap, be set with packing ring on the axle of described roller two ends and support gap location, described axle is provided with lining with the junction of support.
Compared with prior art, the beneficial effects of the utility model are:
The utility model platform truck guiding return pulley is provided with the protruding band of ring-type on the roller, play the guiding role, can be from slippage on the track, and axle adopts bearing to be connected with roller, and area of contact is little, and friction coefficient is little, reduces the burden of cognate mechanism; And not fragile, long service life, whole platform truck good stability is difficult for waving, and can not destroy track.
(4) description of drawings
Fig. 1 is the structural representation of the utility model platform truck guiding return pulley.
Wherein:
(5) specific embodiment
Referring to Fig. 1, a kind of platform truck guiding return pulley that the utility model relates to mainly is made up of support 1, roller 2, roller bearing end cap 3, bearing 4, packing ring 5, lining 6 and axle 7.
Described roller 2 is positioned at support 1 below, and is connected with support 1 by axle 7, and described roller 2 two ends are passed through bearing 4 and are connected with spools 7, and described bearing 4 is outside equipped with roller bearing end cap 3; Be provided with on the described roller 2 that ring-type is protruding is with 2.1.
Be set with packing ring 5 on the axle 7 of described roller 2 two ends and support 1 gap location, described axle 7 is provided with lining 6 with the junction of support 1.Lining 6 the slide relative friction that reduces between axle 7 and the support 1 is set.
Described packing ring 5 is a steel ring.
During use, four jiaos at platform truck are provided with the utility model platform truck guiding return pulley, support 1 is connected and fixed with the platform truck bottom, and support roller 2, the bearing 4 on some rollers 2 supports whole weight, support 1 dismounting arbitrarily, very convenient, just be screwed and can work, removable screw just can take out roller 2 when needing repairing, and not needing to drive a vehicle helps.
Be connected with support 1 again after described roller 2 passes through bearing 4 and axle 7 is connected, can reduce the friction between roller 2 and the axle 7 during motion, not fragile, and because less traction, cognate mechanism is very laborsaving just to be advanced platform truck in the stove, has saved electric resources.
The setting of bearing 4 and packing ring 5 can prevent that roller 2 from teetertottering and swinging, and whole platform truck good stability is difficult for waving, and can not destroy track.
Double-deck thermal insulative board is adopted in the left and right sides of support, and furnace temperature is when 0 ℃ is raised to 1300 ℃, and double-deck thermal insulative board and bearing cap shim thermal insulation effect are fine, and temperature is very high in the stove, and temperature is very low at the bottom of the car, has well protected equipment.
Claims (1)
1. platform truck guiding return pulley, comprise support (1), roller (2) and axle (7), described roller (2) is positioned at support (1) below, and by the axle (7) be connected with support (1), it is characterized in that: the protruding band of ring-type (2.1) is set on the described roller (2), described roller (2) is connected with axle (7) by bearing (4), described bearing (4) is outside equipped with roller bearing end cap (3), be set with packing ring (5) on the axle (7) of described roller (2) two ends and support (1) gap location, described axle (7) is provided with lining (6) with the junction of support (1).
