Novel friction pulley transmission system
Technical field
The utility model belongs to the solid parking field, particularly relates to a kind of novel friction pulley transmission system.
Background technology
Along with the continuous development of Chinese national economy and improving constantly of living standards of the people, automobile has been come into huge numbers of families, and under the limited prerequisite of land resources, parking difficulty becomes puzzlement people's a difficult problem.Three-dimensional parking device arises at the historic moment for solving this difficult problem, and accepts extensively for people.Characteristics such as intelligent storage formula three-dimensional parking device is with its space availability ratio height, and access is easy, and noise is little are subjected to the user and welcome.The storage type tridimensional parking apparatus is of a great variety at present, mainly is divided into broach switch type, sweep switch type or the like.But all there is a common ground in these storage type tridimensional garages in exchanged form, are exactly that exchange process is comparatively complicated: during bicycle parking, vehicle must be carried to the parking stall by carrier, car is placed on the parking stall after, carrier is return the parking stall again; When picking up the car, carrier must be carried to the parking stall, carrier is vehicle retrieval, and then returns the parking stall, and this makes that the storing and taking out car time is longer.The appearance of roller path type stereo garage carrier becomes simply, fast the exchange of carrier and parking stall; In the roller path type stereo parking apparatus that has come into operation at present, two motors of many employings drive simultaneously on the key technology of carrying out the vehicle exchange between carrier and parking stall, be that roller-way drive motors on the carrier and the roller-way drive motors on the parking stall move simultaneously, therefore tighter to the synchronous requirement of two motors, complex structure, the wear rate in the transmission process is higher; In addition, two motor-driven modes have not only increased the cost of parking apparatus, and have increased the consumption to the energy.
The utility model content
The purpose of this utility model is to provide a kind of friction pulley transmission system simple in structure, and this system can effectively reduce the wearing and tearing of drive disk assembly and save the energy.
For achieving the above object, novel friction pulley transmission system of the present utility model comprises driving shaft, chain, bracing frame, friction pulley, bearing, minor axis and sprocket wheel; Described bracing frame is fixed on the carrier side bar of parking stall; Described bearing is installed in the both sides of bracing frame, and the two ends of minor axis are installed in the bearing of bracing frame both sides; Friction pulley is installed on the minor axis near on the side of bracing frame; Described sprocket wheel comprises first sprocket wheel and second sprocket wheel, first sprocket wheel is installed in the opposite side of close bracing frame on the minor axis, stagger with the installation site of friction pulley, described second sprocket wheel is installed on the driving shaft, carries out transmission by chain between this second sprocket wheel and first sprocket wheel; Described driving shaft carries out rotating by driven by motor and drives.
This programme adopts the friction pulley that is arranged on the minor axis to drive roller-way, thereby has reduced by a motor that drives roller-way, and the cost of effectively having saved the roller path type stereo parking apparatus reaches the energy consumption of motor when at every turn stopping, and is simple in structure, economy and durability.
Description of drawings
Fig. 1, be novel friction pulley transmission system schematic diagram.
The specific embodiment
By novel friction pulley transmission system schematic diagram shown in Figure 1 as can be known, this practical novel friction pulley transmission system comprises driving shaft 1, chain 2, bracing frame 3, friction pulley 5, bearing 6, minor axis 7 and sprocket wheel 4; Bracing frame 3 is fixed on the carrier side bar of parking stall, whole drive system and carrier is coupled together, and also can make whole drive system fit reliably with the parking stall friction pulley and separate.Bearing 6 is installed in the both sides of bracing frame 3, and the two ends of minor axis 7 are installed in the bearing 6 of bracing frame 3 both sides.Friction pulley 5 is installed in a side of close bracing frame 3 on the minor axis 7.Described sprocket wheel 4 comprises first sprocket wheel and second sprocket wheel, first sprocket wheel is installed in the opposite side of close bracing frame 3 on the minor axis 7, stagger with the installation site of friction pulley 5, described second sprocket wheel is installed on the driving shaft 1, carries out transmission by chain 2 between two sprocket wheels; Described driving shaft 1 carries out rotating by driven by motor and drives.In order to obtain better transmission effect, spacer 8 can be set on minor axis 7, friction pulley 5, sprocket wheel 4 and 3 of bracing frames separate by spacer.
In this programme, because friction pulley 5 and first sprocket wheel be installed on the same minor axis 7, realized the coaxial rotation of second sprocket wheel and friction pulley 5; First sprocket wheel is fixed on the driving shaft 1, transmission of drive force; First sprocket wheel drives second sprocket wheel by chain 2; Send as access vehicle instruction, checkout gear has detected and the left side or exchange vehicle with the parking stall on the right; Driving shaft 1 is done just commentaries on classics or the counter-rotating that meets command request under the drive of motor, first sprocket wheel drives second sprocket wheel by chain 2, and second sprocket wheel passes to friction pulley 5 to driving force; Friction pulley 5 is again by friction pulley on the frictional force drives parking stall, thereby drives parking stall roller-way motion, realizes the access of vehicle, needing originally to have realized the function of the storing and taking out car that two motors can finish.The utility model has following advantage with respect to two motor-driven modes: (1) adopts the friction pulley transmission, and it is less to wear and tear, and can reduce entreprise cost significantly; (2) transmission efficiency height is saved power consumption, improves economic benefit of enterprises; (3) be easy to safeguard nursing, improve the utilization rate in garage.
