Abstract
A planetary reducer air exhausting gear ring is provided with a gear ring. A threaded hole which is communicated with an inner cavity is formed in the gear ring and an air exhausting valve is arranged on the threaded hole. The air exhausting valve is provided with a valve body, a bonnet, a threaded rod and a sphere. An air exhausting hole is formed in the middle of the valve body, wherein the air exhausting hole is formed by connection of a circular truncated cone hole formed in the upper portion with a cylindrical hole formed in the lower portion. The bonnet is connected with the upper end portion of the valve body, over two through holes are formed in the bonnet ,and the through holes formed in the bonnet are communicated with the air exhausting hole formed in the valve body. The sphere is placed in the circular truncated cone hole. The threaded rod is arranged on the bonnet in a penetrating mode, the threaded rod is connected with the bonnet in a threaded mode, the lower end of the threaded rod is opposite to the sphere, and a nut is connected on the threaded rod. The valve body is connected with the threaded hole formed in the gear ring. When the threaded rod is adjusted, air displacement of the air exhausting valve can be adjusted. The threaded rod is made to stay at a fixed position through matching of the threaded rod and the nut, and therefore the air displacement of the air exhaust valve can keep invariant. In addition, the sphere is made to be matched with the circular conical surface of the circular truncated cone hole through the threaded rod, and therefore the air exhausting valve can be closed.
Description
Technical field
The utility model relates to the retarder technical field, specifically a kind of gear ring of planetary reducer.
Background technique
Planetary reducer at work, its inner air Yin Wendu rising meeting expanded by heating, and do not have venting gas appliance on the existing planetary reducer, the gas behind the expanded by heating can only be forced through the floating sealing ring place and ooze out outside the retarder, the problem of bringing thus is that lubricant oil follows this in floating sealing ring place seepage; Dust, impurity directly enter in the retarder by the floating sealing ring place easily, and then have reduced lubrication effect.
The model utility content
The purpose of this utility model is to provide a kind of planetary reducer exhaust gear ring, and this gear ring can discharge its inner air that expands as required, and the air displacement can regulate.
For achieving the above object, the utility model adopts following scheme: planetary reducer exhaust gear ring, it has a gear ring, on gear ring, have a tapped hole that communicates with its inner chamber, one outlet valve is housed on tapped hole, outlet valve has valve body, bonnet, screw rod and spheroid, the middle part of valve body has exhaust port, exhaust port is connected with the cylindrical hole that is in the bottom by the round platform hole that is in top and constitutes, bonnet connects with the upper end portion of valve body, have plural through hole on the bonnet, the through hole on the bonnet communicates with exhaust port on the valve body, and spheroid is shelved in the round platform hole, screw rod is installed on the bonnet, and be scyewed joint between the two, the lower end of screw rod is relative with spheroid, is connected with nut on the screw rod, and valve body connects with tapped hole on the gear ring.
By such scheme as seen, adjusting screw rod, it is the size of can regulate outlet valve air displacement, by cooperating of screw rod and nut, make screw rod remain on the fixed position, can make the air displacement of outlet valve keep certain, in addition, by screw rod spheroid is cooperated with the conical surface in round platform hole, can make exhaust valve closure.
Rational in infrastructure, the reliable performance of the utility model, the outlet valve that it has can be regulated air displacement as required, and can close reliably, guarantees the working environment of gear ring inside.
Description of drawings
Fig. 1 is the utility model one embodiment's a structural representation;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
The planetary reducer exhaust gear ring that the utility model provides has a gear ring 1, has a tapped hole 1a who communicates with its inner chamber on gear ring 1, and an outlet valve is housed on tapped hole 1a, and outlet valve has valve body 6, bonnet 2, screw rod 3 and spheroid 5.The middle part of valve body 6 has exhaust port, exhaust port is connected with the cylindrical hole 6a that is in the bottom by the round platform hole 6b that is in top and constitutes, bonnet 2 passes through scyewed joint with the upper end portion of valve body 6, have plural through hole 2a on the bonnet 2, through hole 2a on the bonnet 2 communicates with the exhaust port on the valve body, spheroid 5 is shelved among the 6b of round platform hole, screw rod 3 is installed on the bonnet 2 and is scyewed joint between the two, the lower end of screw rod 3 is relative with spheroid 5, be connected with nut 4 on the screw rod 3, valve body 6 connects with tapped hole 1a on the gear ring 1.In addition, between valve body 6 and gear ring 1, be provided with seal ring 7.
As seen from Figure 2, adjusting screw rod 3 is controlled the distance of 5 of its front end and spheroids, when promptly can regulate spheroid 5 rises and the space between the 6b of round platform hole, reach size adjustment to the outlet valve air displacement, by cooperating of screw rod 3 and nut 4, make screw rod 3 remain on the fixed position, can make the air displacement of outlet valve keep certain, in addition, compress spheroid 5 by screw rod 3, spheroid 5 is cooperated with the conical surface of round platform hole 6b, can make exhaust valve closure.
Claims (2)
