Abstract
The utility model relates to a last synchronous pulley (synchronous notched belt ), especially a synchronous pulley with self -cooling effect of mechanical transmission, it includes left ring washer, synchronizing wheel post and right ring washer, they are adorned in an organic whole through the positioning punch combination, are equipped with the spiral wind guide tank on the synchronizing wheel post, are equipped with a plurality of wind -guiding holes on left ring washer and right ring washer, the both ends of wind guide tank respectively with left ring washer and right ring washer on a wind -guiding pore pair connect, the shape in wind -guiding hole is described for the straight hole form or for the horn mouth. Owing to be equipped with the wind guide tank on the synchronizing wheel post, so the band pulley is on -stream because of the produced heat that rubs, accessible wind guide tank via the discharge space of outside of the wind -guiding mouth on the retaining ring to reduce the bulk temperature of band pulley, prolonged the life of synchronous pulley and hold -in range.
Description
Technical field
The utility model is the synchronous pulley on a kind of mechanical driving device（Timing belt）, it is particularly a kind of to have certainly
The synchronous pulley of cooling effect.
Background technology
Synchronous pulley must be used cooperatively with Timing Belt, and in running up, synchronous pulley can be because friction with Timing Belt
And in the case of producing high temperature, particularly confined space, temperature can reach up to a hundred degrees Celsius.In the effect expanded with heat and contract with cold
Under, it is easy to cause synchronous pulley to deform and centre-to-centre spacing change, and then have influence on gearratio, this is for precision drive equipment
It is not allow appearance.At present general synchronous pulley, due to the structure in terms of not no radiating, so cannot avoid expanding with heat and contract with cold
It is negatively affected.
The content of the invention
The purpose of this utility model is the defect in order to overcome existing synchronous pulley not have radiator structure, and invention one kind is provided with
Wind guide tank with the synchronous pulley from cooling effect.
The purpose of this utility model is as follows realizing：The synchronous pulley with from cooling effect,
Including left ring washer, synchronous wheel post and right ring washer, they are assembled into one by assembling location hole, and in synchronous wheel post spiral is provided with
Shape wind guide tank, is provided with multiple air-guiding holes on left ring washer and right ring washer, the two ends of wind guide tank respectively with left ring washer and right ring washer on
An air-guiding hole docking.
The air-guiding hole is shaped as straight hole shape or for bell mouth shape.
Good effect of the present utility model is as follows：Because synchronous wheel post is provided with wind guide tank, thus belt wheel in operation because
Heat produced by friction, the space that can be discharged to the outside via the air guide hole on back-up ring by wind guide tank, so as to reduce belt wheel
Bulk temperature, extend the service life of synchronous pulley and Timing Belt.
Description of the drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model installation diagram
In figure：The right ring washer of synchronous wheel post 3 of 1 left ring washer 2
The air-guiding hole of 45 wind guide tank of assembling location hole 6.
Specific embodiment
As shown in Fig. 1 Fig. 2, the synchronous pulley with from cooling effect, including left ring washer 1, synchronous wheel post 2 and right shelves
Circle 3, they are assembled into one by assembling location hole 4, spirality wind guide tank 5 are provided with synchronous wheel post 2, in the He of left ring washer 1
Right ring washer 3 is provided with multiple air-guiding holes 6, the two ends of wind guide tank 5 respectively with left ring washer 1 and right ring washer 3 on an air-guiding hole 6 pairs
Connect.
The air-guiding hole 6 is shaped as straight hole shape or for bell mouth shape.
When using, synchronous pulley must be used cooperatively with Timing Belt, and synchronous pulley material can be closed for 40Cr, 45# steel, aluminium
Gold, copper, nylon etc..Because synchronous wheel post is provided with wind guide tank, so belt wheel can lead in operation because of the heat produced by friction
The space that wind guide tank is discharged to the outside via the air-guiding hole on back-up ring is crossed, so as to reduce the bulk temperature of belt wheel, synchronization is extended
The service life of belt wheel and Timing Belt.Air-guiding hole on the back-up ring of left and right can be replaced by plane air-guiding hole according to intake demand
Or horn-like air-guiding hole.
Claims (2)
1. a kind of synchronous pulley with from cooling effect, including left ring washer, synchronous wheel post and right ring washer, they are fixed by assembling
Position hole is assembled into one, it is characterised in that：Spirality wind guide tank is provided with synchronous wheel post, is provided with left ring washer and right ring washer
Dock with an air-guiding hole on left ring washer and right ring washer respectively at multiple air-guiding holes, the two ends of wind guide tank.
2. the synchronous pulley with from cooling effect according to claim 1, it is characterised in that：The shape of the air-guiding hole
