Abstract
A multi-freedom-degree idler wheel comprises a wheel frame and an idler wheel, wherein the whole wheel frame is in a short cylinder shape, three pits with openings on the sides of the cylinder surface of the wheel frame are evenly distributed on two end faces of the wheel frame, bottom surfaces of the pits on the two end faces of the wheel frame are adjacently connected and staggered by a 60-degree angle. A fixed shaft perpendicular to a wheel frame shaft is arranged in each pit, a waistdrum-shaped idler wheel is movably sleeved on the fixed shaft, and a transmission shaft hole is positioned at the axial center of the wheel frame. The multi-freedom-degree idler wheel replaces a structure formed by two pieces with an integral structure, thereby being convenient to manufacture and assemble, improving whole strength and providing an important component with low cost and reliable quality for a heavy-type vertical steering conveyor.
Description
Technical field:
The utility model relates to a kind of parts of roller conveyor.
Background technique:
At present, the roller conveyor that transports heavy article is many to be made of the single-degree-of-freedom roller, and it is flexible that its shortcoming is that the steering gear is owed, and floor space is big.Multivariant roller steering is flexible, and it comprises the wheeled and four stars roller type of spherical universal.The former is not suitable for the powered rollers conveyor, though the latter can be applicable to power and unpowered roller conveyor, because intensity is relatively poor, is only applicable to carry the roller conveyor of light-duty article.For this reason, claimant parent company (Dema Material Flow System Engrg. Co., Ltd., Huzhou) had once designed " heavy multi-freedom degree roller " (patent No. is: ZL 00259225.8) that is applicable to heavy roller conveyor, it is to interlace 60 ° by two roller group sheets, matched by the tenon tenon groove on the wheel carrier, and be connected with wheel shaft and bearing thereof by axle hole, form with nut is fixing again, wherein every roller group sheet has wheel carrier and roller, the all sides of wheel carrier are evenly equipped with three bayonet slot, roller passes through the Bearing Installation at stationary axle and two ends thereof in each bayonet slot, also is provided with the groove of being convenient to install and fix axle between all each bayonet slot of side of wheel carrier.The advantage of this heavy type multi-freedom degree roller be turn to flexibly, convenient, by the conveyor the steering gear reliable operation of its body plan, durable and floor space is little, but structure is complicated, manufacture cost is higher.
Summary of the invention:
The purpose of this utility model is that above heavy multi-freedom degree roller is carried out technological improvement, thereby a kind of advantage that not only has above heavy multi-freedom degree roller is provided, and structure is simpler, and is easy to assembly, the novel multi-freedom degree roller that manufacture cost is lower.
The technological scheme that realizes above-mentioned purpose is: it has wheel carrier and roller, wheel carrier integral body is short cylindrical, be evenly equipped with three pits on its both ends of the surface respectively in the cylinder side opening, the bottom surface of each pit of both ends of the surface interlace 60 ° adjacent, be equipped with in each pit with wheel frame axle to perpendicular stationary axle, dolioform roller is sleeved on the stationary axle versatilely, and the axial centre of wheel carrier offers the transmission axis hole.
The utility model has substituted the structure of former two combination formings with integral structure, the simpler compactness of overall structure, go slick conveniently, reliable operation, the intensity height, and cost is lower, for make the steering gear floor space little, can make the heavy logistics conveyor of the article vertical duction that transports that a kind of comparatively ideal basic building block is provided easily.
Description of drawings:
Accompanying drawing is the three-dimensional decomposition texture schematic representation of the utility model.
Embodiment:
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Wheel carrier 1 and roller 5 all adopt aluminum alloy or the good material of other light weight intensity high wear resistances to make.Wheel carrier 1 is designed to an integral body that is short cylindrical, is evenly equipped with three pits 8 in the cylinder side opening on its both ends of the surface respectively, the bottom surface of each pit 8 of both ends of the surface interlace 60 ° adjacent, be equipped with in each pit 8 and wheel carrier 1 axial perpendicular stationary axle 3.Roller 5 is that hollow is dolioform, and forced axle sleeve 4 is installed in the axis hole of two ends, and this axle sleeve 4 adopts wear-resisting engineering plastics to make.Roller 5 is installed in the pit 8 by stationary axle 3, and can rotate flexibly around stationary axle 3.Stationary axle 3 two ends are fixing with hollow round pin 2 and locking nut 6.Then offer groove 9 and the pit 7 of being convenient to install hollow round pin 2 and locking nut 6 on pit 8 sidewalls.Then constitute a circle if the peripheral, axial camber line of 3 dolioform rollers of wheel carrier 1 ipsilateral coupled together.The transmission axis hole 10 at wheel carrier 1 center is hexagon, can be installed in whole multi-freedom degree roller on the frame face of roller conveyor easily, forms multi-freedom degree and carries.
