Abstract
The invention relates to a high-speed rotating shaft thrust disc locking mechanism on a high-speed centrifugal compressor, which can ensure that a thrust disc does not get loose during the operation and operates stably. The high-speed rotating shaft thrust disc locking mechanism comprises a pinion, a high-speed rotating shaft and thrust discs, wherein the pinion and the high-speed rotating shaft are connected into a whole, and the thrust discs are respectively arranged at two sides of the pinion of the high-speed rotating shaft. The high-speed rotating shaft thrust disc locking mechanism is characterized in that mounting grooves are respectively arranged at the outer sides of positioning shaft necks of the two thrust discs of the high-speed rotating shaft, half baffle rings of a semi-ring structure are sleeved in the mounting grooves in pairs, and fastening rings are sleeved at the excircle surfaces of the half baffle rings of the semi-ring structure.
Description
(1) technical field
The present invention relates to high speed centrifugation compression device field, be specially the high speed rotating shaft thrust disc locking mechanism on a kind of high speed centrifugation compression device.
(2) background technique
Existing high speed centrifugation compression device, comprise centrifugal compressor and centrifugal blower, gearwheel is installed in the low speed rotating shaft, small gear and high speed rotating shaft are integrally manufactured, the low speed rotating shaft is by the gear transmission of gearwheel and small gear, the driving high speed rotating shaft runs up, and then drive installation is at the centrifugal impeller pressurized gas of high speed rotating shaft end, the thrust disc structure is adopted in its small gear both sides on high speed rotating shaft, with the axial force transmission on the high speed rotating shaft to the low speed rotating shaft, bear by the thrust bearing in the low speed rotating shaft, and high speed rotating shaft only need arrange that the radial support bearing gets final product.For thrust disc firmly being installed on the small gear both sides on the high speed rotating shaft, Chang Yong construction design method was only to arrange a thrust disc separately in the small gear both sides in the past, and all selected bigger magnitude of interference for use, adopted hydraulic method that thrust disc directly is pressed into assembling.During this equipment operation, thrust disc easily gets loose, and its run stability is poor.
(3) summary of the invention
At the problems referred to above, the invention provides the locking mechanism of the high speed rotating shaft thrust disc on a kind of high speed centrifugation compression device, it can guarantee thrust disc not getting loose when operation, has guaranteed its run stability.
Its technological scheme is such: it comprises small gear, high speed rotating shaft, thrust disc, small gear and high speed rotating shaft are connected as a single entity, the small gear both sides of described high speed rotating shaft are equipped with described thrust disc respectively, it is characterized in that: the locating journal outside of two thrust discs of described high speed rotating shaft is opened respectively mounting groove is housed, half baffle ring of semicircular ring structure is set in the described mounting groove in pairs, and the periphery of half baffle ring of described semicircular ring structure is set with retaining ring.
It is further characterized in that: the end face of described retaining ring has tapped through hole; Described thrust disc has axial power transmission circular groove at the end face near small gear one side.
In the said structure of the present invention, the locating journal outside of two thrust discs of described high speed rotating shaft is opened respectively mounting groove is housed, half baffle ring of semicircular ring structure is set in the described mounting groove in pairs, the periphery of half baffle ring of described semicircular ring structure is set with retaining ring, the locking mechanism that half baffle ring of described retaining ring, semicircular ring structure is formed can guarantee thrust disc not getting loose when operation, has guaranteed its run stability.
(4) description of drawings
Fig. 1 is the structural representation of plan view of the present invention;
Fig. 2 is the left view of Fig. 1.
(5) embodiment
See Fig. 1, Fig. 2, the present invention includes small gear 1, high speed rotating shaft 2, thrust disc 3, small gear 1 is connected as a single entity with high speed rotating shaft 2, small gear 1 both sides of high speed rotating shaft 2 are equipped with thrust disc 3 respectively, the locating journal outside of two thrust discs 3 of high speed rotating shaft 2 is opened respectively mounting groove 5 is housed, half baffle ring, 4 paired mounting of semicircular ring structure are in mounting groove 5, and the periphery 6 of half baffle ring 4 of semicircular ring structure is set with retaining ring 7.The end face 8 of retaining ring 7 has tapped through hole 9; Thrust disc 3 has axial power transmission circular groove 10 at the end face near small gear 1 one sides.Tapped through hole 9 uses as the jack-up hole when dismounting, and axially power transmission circular groove 10 transmits axial force.
