Abstract
The utility model belongs to the technical field of the agricultural machine speed change gear technique and specifically relates to a belt tensioning speed change mechanism is related to. Its characteristics are including the driving shaft, the driving shaft on install driving pulley, driving pulley passes through the belt and is connected with from the driven pulleys, from the driven pulleys installs on the driven shaft, is provided with the take -up pulley between driving pulley and the from the driven pulleys. Its mode that adopts the belt tensioning speed governing through the band pulley that sets up the radius variation in size on the driven shaft, realizes the conversion between the friction speed, has good speed governing effect. Being provided with different tensioning poles on its take -up pulley and having different size and extension, the tensioning pole is overhanging, is convenient for operate. It has reduced work step, has saved manpower and materials. This working process the cost is reduced has improved the operating efficiency. Have simple structure, small, light in weight, connection reliable, install and remove and articulate advantages such as convenient.
Description
Technical field
The utility model relates to farm machinery speed change gear technical field, especially relates to a kind of belt tension gear.
Background technique
Along with state reform exploitation, the automotive transmission of China achieves good development, and the potentiality of China in automatic gearbox market are also very huge.Along with the development in Foreign Automobile market, adopt the demand of automatic transmission to strengthen, in China's automobile market, the sales volume of automatic transmission type accounts for about 35% of total sales volume in recent years.Automatic transmission market in recent years with 20% speed increment, but the industrial development of China delayed causing starts to walk evening in speed changer research and development field, weak foundation, the a part of new product of independent brand enterprise development, but most product does not form industrialization, product technology route neither be very clear.The complex structure of automatic transmission, R&D costs are high, and the difficulty of processing of zero device is large, and research and development technology and production technology are monopolized by overseas enterprise, its core technology and the main dependence on import of product.The value cost introduced is large.And the Applicable scope in agricultural is wideless, and the technology in the self-service speed governing of agricultural machinery is comparatively short of.
At present, China needs and installs simple and easy, the reliable speed regulating mechanism of adjusting function in agricultural speed governing.In agricultural gearshift adjustment, usually there is a difficult problem for work under bad environment, speed change difficulty, high, the inconvenient maintenance of practical cost.Operationally, main exist larger dust and foreign material to farm implements, causes speed change malfunctioning, occur the problem of job insecurity.Cause the labor intensity of the workman when agricultural operation large, manufacturing efficiency is low, and the cost of installation and use of facility is high.The subject matter that current existing variable regulating mechanism exists is: function singleness, narrow application range, and mechanism is complicated, productivity is not high.
Summary of the invention
The purpose of this utility model is avoid the defect of prior art and provide a kind of belt tension gear, efficiently solves prior art Problems existing.
For achieving the above object, the technological scheme that the utility model is taked is: described a kind of belt tension gear, be characterized in comprising driving shaft, described driving shaft is provided with driving pulley, driving pulley is connected with driven pulley by belt, driven pulley is arranged on driven shaft, is provided with Idle wheel between driving pulley and driven pulley.
Described driven pulley is made up of the belt wheel that radius is different.
The corresponding belt of described Idle wheel is arranged, and is provided with Idle wheel, Idle wheel is provided with nutted rod under every bar belt.
The beneficial effects of the utility model are: described a kind of belt tension gear, and it adopts the mode of belt tension speed governing, by arranging the different belt wheel of radius size on driven shaft, realizes the conversion between friction speed, has good speed governing effect.Its Idle wheel is provided with different nutted rods to be of different sizes and extension, nutted rod is overhanging, is convenient to operate.Which reduce job step, save manpower and materials.This working procedure reduces cost, improves operating efficiency.There is the advantages such as structure is simple, volume is little, lightweight, connection is reliable, mounting or dismounting mounting is convenient.
Accompanying drawing explanation
Fig. 1 is structural principle schematic diagram of the present utility model;
Fig. 2 is the structural principle schematic diagram of Idle wheel in the utility model Fig. 1.
Shown in figure: 1. driving pulley; 2. driving shaft; 3. belt; 4. Idle wheel; 5. nutted rod; 6. driven pulley; 7. driven shaft.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, described a kind of belt tension gear, be characterized in comprising driving shaft 2, described driving shaft 2 is provided with driving pulley 1, driving pulley 1 is connected with driven pulley 6 by belt 3, driven pulley 6 is arranged on driven shaft 7, is provided with Idle wheel 4 between driving pulley 1 and driven pulley 6.
Further, described driven pulley 6 is made up of the belt wheel that radius is different.
Further, the corresponding belt 3 of described Idle wheel 4 is arranged, and is provided with Idle wheel, Idle wheel is provided with nutted rod 5 under every bar belt.
Described a kind of belt tension gear, its Idle wheel 4 is separately positioned on the below of every band, when a certain speed of needs, is just lifted by the Idle wheel 4 of correspondence, carries out tensioning action to belt 3.When one of them Idle wheel 4 tensioning operation, other Idle wheels 4 are in relaxed state, and therefore, other corresponding belts 3 are also in relaxed state, now there is no gap certain between the belt 3 of tensioning and belt wheel, cause it can not reach the effect of transmission.The band of corresponding tensioning is only had to have the effect of transfer rate and power.Thus reach and can select different speed, certain adjustment is carried out to the operating rate of agricultural equipment.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
1. a belt tension gear, it is characterized in that comprising driving shaft, described driving shaft is provided with driving pulley, and driving pulley is connected with driven pulley by belt, driven pulley is arranged on driven shaft, is provided with Idle wheel between driving pulley and driven pulley.
2. a kind of belt tension gear as claimed in claim 1, is characterized in that: described driven pulley is made up of the belt wheel that radius is different.
