The tensioning belt wheel structure is composed of two sets of symmetrical tensioning belt wheel assemblies (1), and is characterized in that the tensioning belt wheel assemblies (1) comprise belt wheel outer plates (2) and belt wheel inner plates (3). The belt wheel outer plates (2) and the belt wheel inner plates (3) are fixedly connected. Quadruple surface flanges are arranged on the outer circumferential surfaces of the symmetrical tensioning belt wheel assemblies (1). Inner holes and shaft sleeves A (4) are fixedly connected. Bearings (9) are arranged between the shaft sleeves A (4) and shaft sleeves B (8). Check rings (5), spacer sleeves A (6) and spacer sleeves B (7) are arranged between the two sets of symmetrical tensioning belt wheel assemblies (1). The spacer sleeves A (6) are arranged on the check rings (5), and the spacer sleeves B (7) are arranged on the shaft sleeves B (8). The tensioning belt wheel structure has the advantages of being capable of ensuring contact in a press fit adjusting mode, light in weight, even in heat dissipation, and convenient to machine.
Description
Technical field
The utility model relates to the belt drive unit field, relates in particular to a kind of tensioner belt sheave structure.
Background technique
In belt transmission, expansion tightening wheel can be adjusted tension force according to the different tightness of belt, makes the transmission system stability and safety reliable, and belt operates steadily, and reduces noise, prevents to skid.The blower fan of large-scale cotton harvester is by the running of tetrad v belt transferring power, and expansion tightening wheel contacts by cylinder regulating and controlling belt elasticity with belt is outside.Expansion tightening wheel of the prior art, heavier, loading and unloading inconvenience, and can not effectively contact with belt.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of pressing adjustment contact that can guarantee is provided, and is in light weight, and heat radiation is even, the tensioner belt sheave structure of being convenient to process.
The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Tensioner belt sheave structure of the present utility model, two cover tensioner pulley assemblies by symmetry are formed, wherein: described tensioner pulley assembly comprises belt pulley outside plate, belt pulley inner panel, the belt pulley outside plate is fixedlyed connected with the belt pulley inner panel, and its outer peripheral surface forms tetrad surface flange, endoporus is fixedlyed connected with axle sleeve A; Be provided with bearing between axle sleeve A and the axle sleeve B, be provided with back-up ring, spacer A, spacer B between the two cover tensioner pulley assemblies of symmetry, spacer A is positioned at the back-up ring place, and spacer B is positioned at axle sleeve B place.
Above-mentioned tensioner belt sheave structure, wherein: described belt pulley outside plate and belt pulley inner panel are sheet metal.
Above-mentioned tensioner belt sheave structure, wherein: described belt pulley outside plate and belt pulley inner panel are fixedly connected by welding.
Above-mentioned tensioner belt sheave structure, wherein: described bearing is a ball bearing.
The utility model compared with prior art has tangible advantage and beneficial effect.By above technological scheme as can be known, described tensioner pulley assembly comprises belt pulley outside plate, belt pulley inner panel, and the belt pulley outside plate is fixedlyed connected with the belt pulley inner panel, and its outer peripheral surface forms tetrad surface flange, endoporus is fixedlyed connected with axle sleeve A; Adopt sheet metal by formed in mould belt pulley inner panel and belt pulley outside plate, form tetrad surface flange after the seam naturally, can effectively contact, and heat radiation is evenly with belt, and easy to process, economical with materials, weight reduction.Be provided with back-up ring, spacer A, spacer B between the two cover tensioner pulley assemblies of symmetry, spacer A is positioned at the back-up ring place, and spacer B is positioned at axle sleeve B place, and it is convenient that the overall structure assembling is adjusted.In a word, belt pulley inner panel of the present utility model and belt pulley outside plate form tetrad surface flange naturally after the seam, can effectively contact with belt, and heat radiation is evenly in light weight, is convenient to processing.
