Abstract
The utility model relates to an elliptical roller coupling, which adopts end covers, inner gear rings and outer gear sleeves. The end cover is sheathed on the outer gear sleeve, and the outer gear sleeve is provided with a shaft hole provided with a key groove. The inner gear ring and the outer gear sleeve are respectively provided with a plurality of concave half-cylinder surfaces, and the circular hole formed by two corresponding concave half-cylinder surfaces is provided with the elliptical roller. The end cover sheathed on the outer gear sleeve adopts a screw bolt to be connected by matching with the inner gear ring. The part of the end cover matched with the outer gear sleeve is provided with a sealing ring, and a gap is left between two outer gear sleeves. The inner gear rings are engaged mutually and are fixed together, and the inner gear ring is provided with the screw plug of an oil feeding hole. The utility model has the advantages of favorable capacity of compensating comprehensive deviation of two shafts, high transmission efficiency, large torque, smooth running, low noise and long service life.
Description
The utility model relates to a kind of coupling, particularly oval roller coupling.Oval roller coupling is a kind of movable coupling product.
The coupling that is used to be widely used in industrial machinery now has gear coupling, gear coupling is called for short the toe joint hand, the toe joint hand is important and more valuable mechanical rapid wear basic part, it uses on the medium-sized and heavy duty equipment extensively in metallurgy, lifting etc., its basic structure is gear and gear engagement, because due to its structure, be in contact with one another that stress is big, easy to wear, the life-span short.
The purpose of this utility model is, improves at above-mentioned the deficiencies in the prior art, proposes and design oval roller coupling, as the upgrading products of existing gear coupling.
Technical solution of the present utility model is, adopt two end caps, two external tooth covers, end cap is sleeved on the external tooth cover, axis hole is arranged on the external tooth cover, keyway is arranged in the axis hole, it is characterized in that, adopted the ring gear that cooperatively interacts with external tooth cover, ring gear, external tooth cover have several recessed semi-cylindricals respectively, in the circular hole that two corresponding recessed semi-cylindricals form oval roller are housed, and the end cap that is sleeved on the external tooth cover adopts bolt and ring gear to connect.
It is characterized in that seal ring is equipped with at the position that end cap cooperates with external tooth cover.
It is characterized in that, leave the gap between two external tooth covers.
It is characterized in that ring gear is meshing with each other and adopts bolt, packing ring, nut to fix.
It is characterized in that, the oil hole plug screw is housed on the ring gear.
It is characterized in that ring gear, external tooth cover have several recessed semi-cylindricals to be evenly distributed on the position that ring gear and external tooth cover cooperatively interact respectively.
The utility model has the advantages that: 1) two recessed semi-cylindricals and contacting of oval roller are circular arc line contact (being the some contact during angle of cut of toe joint hand at axle) when two angles of cut change, contact stress is little, wearing and tearing less, the life-span is long, can dwindle physical dimension.2) recessed semi-cylindrical and oval roller to contact relative position unrestricted, and flexibly, spend or bigger so the angle of cut that diaxon allows can reach 1.5.3) contact gap of recessed semi-cylindrical and oval roller is little, so operation accurately, steadily, noise is low, can adapt to connecting of high speed shaft.4) two crossed axis angles change recessed semi-cylindrical and oval roller when moving axially relative movement for rolling (the toe joint hand must slide), so friction loss is little, the transmission efficiency height, temperature rise is low, energy-conservation, maintenance and lubricating simply.5) so tooth is formed by the two halves cylndrical surface root intensity height, not easy tooth-breaking.6) be suitable for connecting two horizontal coaxial line transmission shafts, have the performance of the relativity shift of very high compensation diaxon, the motion stationary noise is lower, but the loading capability height.
Fig. 1, basic structure schematic representation of the present utility model
Below, describe embodiment of the present utility model with reference to the accompanying drawings in detail.
As shown in Figure 1, the utility model is made up of external tooth cover 1,12, bolt 2,7, spring washer 3,8, seal ring 4, ring gear 5,6, nut 9, oval roller 10, end cap 11, oil fill plug 13.Adopt two end caps 11, an end cap 11 to be sleeved on the external tooth cover 1, an end cap 11 is sleeved on the external tooth cover 12, on the external tooth cover 1,12 axis hole 13 is arranged all, keyway 14 is arranged in the axis hole 13, ring gear 5 cooperatively interacts with external tooth cover 1, ring gear 6 cooperatively interacts with external tooth cover 12, ring gear 5,6, external tooth cover 1,12 have several recessed semi-cylindricals respectively, ring gear 5,6, external tooth cover 1,12 have several recessed semi-cylindricals respectively, and they are evenly distributed on the position that ring gear 5 and external tooth cover 1, ring gear 6 and external tooth cover 12 cooperatively interact.In the circular hole 16 that two corresponding recessed semi-cylindricals form oval roller 10 is housed, two end caps 11 that are set on the external tooth cover 1,12 adopt bolt 2, spring washer 3 and plain washer to connect with ring gear 5,6 separately.Two end caps 11 all are equipped with seal ring 4 with the position that external tooth cover 1,12 cooperates respectively.Leave gap 15 between the position that external tooth cover 1,12 cooperatively interacts.Ring gear 5,6 is meshing with each other, and adopts bolt 7, spring washer 8, nut 9 to fix.Ring gear 6 has oil hole, and it is equipped with oil hole plug screw 17.Using method of the present utility model is: 1) unclamp bolt 7, spring washer 8, nut 9, disintegrate into two, end cap 11 is sleeved on axle goes up and shift onto the position.2) according to the assembly technology of axis hole with axle, external tooth cover 1 is contained on the axle, external tooth cover 1 end face and axial end flush, and fixing.During hot charging, should prevent that the flank of tooth from crossing thermal annealing.3) then internal tooth casing 5 is sleeved on the external tooth cover 1.4) aim at the circular hole 16 that two recessed semi-cylindricals form, insert grease, the oval roller 10 of packing into packages seal ring 4 and end cap 11, loads onto compression spring, tights a bolt 2.5) second half coupling that uses the same method.6) check to adjust drift angle≤1 ° 30 of diaxon ', to good seam and bolt hole and fix with bolt 7, spring washer 8, nut 9.7) the setting stick car does not have card and bumps phenomenon, check errorless after, can start preliminary operation and operation.8) daily spot check, patrol and examine in the process, whether caution'soperation normal, have no abnormal sound and bolt moving, and in time handle.9) lubricated, high temperature area operation 3-6 month, the normal temperature operation was turned on oil hole plug screw 13 in 6-9 month, and grease up is tightened oil hole plug screw 13 again.
The utility model can also be made the identical series product of main structure with requirement according to different Environmental Conditions.For example, with ring gear 5,6 processing and fabricating that is integrated, save bolt 7, spring washer 8, nut 9.Perhaps external tooth cover 12 and internal tooth casing 6 are integrated and directly join company with internal tooth casing 5 engagements, use bolt 7, spring washer 8, nut 9 fixedly connected, save the recessed semi-cylindrical of processing and by several circular holes 16 that form by two recessed semi-cylindricals one to one and the oval roller 10 in the circular hole of packing into.
