Description

Belt pulley installing mechanism
Technical field
This utility model relates to a kind of mounting structure, the specifically installing mechanism of belt pulley。
Background technology
When the less building of scale and fitting-out work, the service efficiency of large-scale blender is low, and then market development need answered by a kind of pony mixer, arises。At present, the power drive mechanism holding capacity of traditional pony mixer is too small, and belt pulley beat (is connected with engine crankshaft outfan mainly due to pulley side relatively greatly, belt pulley opposite side is not connected with any object, balance is poor), belt is easy to wear, and reliability is poor。
Utility model content
This utility model is intended to provide a kind of belt pulley installing mechanism, to reduce belt pulley beat, makes belt abrasion reduce。
Belt pulley installing mechanism in this programme, including frame and belt pulley, described pulley side is connected with engine crankshaft;Also include fixing bolt and fixing swivel nut, described belt pulley opposite side is provided with wheel core housing, described band wheel core housing is also associated with bearing block, it is provided with bearing between described band wheel core housing and bearing block, described bearing block is provided with installation otic placode, and described installation otic placode is provided with installing hole, and described frame is provided with the location hole corresponding with position of mounting hole, hole, described location is shoulder hole, and hole, described location includes narrower bore and in the wide aperture installed between otic placode and narrower bore;Described fixing bolt is provided with external screw thread, and described fixing swivel nut is jointly provided with the female thread mated with fixing bolt external screw thread with narrower bore, and described fixing swivel nut is provided with external screw thread, and described installing hole is jointly provided with the female thread mated with fixing swivel nut external screw thread with wide aperture;Described fixing bolt is oppositely oriented with the external screw thread on fixing swivel nut, and described fixing swivel nut upper end is provided with the extension being held on fixing bolt and installing between otic placode。
Adopt the technical solution of the utility model, have the following technical effect that
1, owing to hole, location adopts the female thread of two kinds of different rotation directions to be connected with fixing bolt and fixing swivel nut respectively, and described fixing swivel nut is together to be formed with the narrower bore in hole, location to threaded with fixing bolt external screw thread, so fixing bolt, fixing swivel nut just can be connected as a single entity with frame, and general mechanical vibration can not affect the helicitic texture of two kinds of rotation directions simultaneously;In like manner, described installation otic placode, fixing swivel nut also can be connected as a single entity with frame, then by fixing bolt, fixing annexation between swivel nut and frame, prevent from installing otic placode affected by mechanical vibration and and connection between frame occur loosening。
2, the operating of belt pulley opposite side is stablized by bearing and bearing block, it is to avoid the belt pulley deflection caused by nonequilibrium mounting structure, thus wearing and tearing between belt and belt pulley。
Further, the cross section of the extension of described fixing swivel nut is hexagon。
In order to facilitate manual operation, the cross section of the extension of fixing swivel nut is set to hexagon by spy。
Further, two bearings it are provided with between described band wheel core housing and bearing block。
Arranging two bearings is to divide equally the radial component that belt pulley is transmitted, it is to avoid single bearing premature breakdown。
Further, the outer peripheral face of described belt pulley is provided with the annular groove of spacing belt。
What belong to belt is spacing herein, it is prevented that occur that belt is dislocated from belt pulley。
