The cross coupling device has the characteristics of realizing suspended connection, conveying comparatively large torque moment, realizing stable transmission and having smaller volume, is applicable to the coupling of transmitting the rotation along the same direction downwards from the same vertical shaft in the device, and can be widely applied to the secondary coupling of a vertical type crusher, the secondary coupling of a lead stripping machine,and the like.
Description
Technical field
The utility model relates to mechanical transmission fields, and particularly a kind of elastic expansion piece ring twin shaft cover hangs the cross coupling arrangement.
Background technique
In the prior art, when device interior down transmits the rotation of same direction at same vertical shaft, the main mode that adopts the lengthening axle sleeve.This transfer mode because axle sleeve is longer, is easy to generate swing during rotation, make that its running is steady inadequately, and when installing spring bearing additional in its underpart, its sealing is relatively more difficult again.
Summary of the invention
Deficiency at the prior art existence, technical problem to be solved in the utility model provides a kind of device interior that is used for, and when same vertical shaft down transmits the rotation of same direction, can realize hanging connection, can transmit again, and can realize the transmission coupling arrangement of smooth transfer than high pulling torque.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that a kind of elastic expansion piece ring twin shaft cover of design hangs the cross coupling arrangement:
Comprise expansion axle sleeve 2;
A, also include the upper-end surface and have the countershaft cover 7 that criss-cross groove, its endoporus top have one inner groove;
The edge, upper-end surface of B, expansion axle sleeve 2 has criss-cross projection, has one outer groove on the outer cylinder of its underpart, and has the axial bore that several communicate with described outer groove on its post jamb; The outer cylinder of expansion axle sleeve 2 is sleeved in the endoporus of countershaft cover 7;
C, the several piece watt shape expanding ring 3 of device in the outer groove of expansion axle sleeve 2 are pressed in the inner groove of countershaft cover 7 by expansion bearing pin 1, make between the inner groove of its outer groove that is in expansion axle sleeve 2 and countershaft cover 7.
Expansion bearing pin 1 is made by elastic material.
Elastic expansion piece ring twin shaft cover of the present utility model hangs the cross coupling arrangement, adopts the twin shaft cover form of expansion axle sleeve and countershaft cover cooperation, the countershaft cover is prolonged vertically be implemented in the rotation that the same axis line down transmits same direction; And in countershaft cover endoporus, install the axle sleeve bearing additional and support, realize smooth transfer; Simultaneously, use expanding ring, utilize the crowded power of expansion bearing pin, countershaft cover and the suspension of expansion axle sleeve are connected as one; And, crosswise groove and projection that the upper-end surface of countershaft cover and expansion axle sleeve is designed to cooperate, thereby, can realize transmission than high pulling torque; In addition, because the elastic expansion element apparatus is between expansion axle sleeve and countershaft cover, volume is less, so can be used for the device interior use.
Description of drawings
Accompanying drawing 1 is the main sectional view along B-B axis of the present utility model;
Accompanying drawing 2 is sectional views of bowing along A-A axis of the present utility model.
Among the figure: the 1st, expansion bearing pin, the 2nd, expansion axle sleeve, the 3rd, expanding ring, the 4th, workpiece axle sleeve, the 5th, axle sleeve bearing, the 6th, workpiece shaft sleeve key, the 7th, countershaft cover, the 8th, main shaft seat, the 9th, main shaft, the 10th, main shaft key.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model is made of main shaft 9, expansion axle sleeve 2, countershaft cover 7, expanding ring 3 and expansion bearing pin 1.
The cross section of expansion axle sleeve 2 is "T"-shaped, and its endoporus has the keyway that cooperates with main shaft key 10, and the bottom outer cylinder has the outer groove that holds expanding ring 3; On the upper-end surface of its post jamb, axially have several holes that hold expansion bearing pin 1 that communicate with described outer groove (quantity in this hole determines that according to driving torque power needs present embodiment is designated as eight).The end face edge has criss-cross projection thereon.
The upper-end surface of countershaft cover 7 has criss-cross groove, and the tapering that the bottom is slightly up-small and down-big has a step in the underpart, is used for device workpiece axle sleeve 4, is connected by workpiece shaft sleeve key 6; In the middle of the endoporus of countershaft cover 7 step is arranged, be used for installation shaft cover bearing 5, it also is equipped with seal ring in the position slightly down; The endoporus top of countershaft cover 7 has the inner groove that is used to hold expanding ring 3.
Expanding ring 3 is watt shape ring pieces that are divided at least three strands or above quantity (present embodiment is made as four strands) by annulus, and the corresponding part of itself and expansion bearing pin 1 has arc-shaped notch.Expansion bearing pin 1 is made by nylon elastic material or other elastic material.
During assembling, the bottom with countershaft cover 7 is sleeved on the top of the main shaft seat 8 of " Y " shape that the cross section is hollow earlier, and seal ring and axle sleeve bearing 5 are installed; Main shaft 9 upwards stretches out in main shaft seat 8, and expanding ring 3 is packed in the outer groove of expansion axle sleeve 2 outer cylinders, is set in the lump on the main shaft 9, connect by main shaft key 10, at this moment, the crosswise projection at edge, expansion axle sleeve 2 upper-end surface embeds countershaft and overlaps in the crosswise groove of 7 upper-end surfaces, forms cross and connects; Again expansion bearing pin 1 is inserted by the hole of expansion axle sleeve 2 upper-end surfaces, at this moment, being loaded on expanding ring 3 in expansion axle sleeve 2 outer grooves is inflated bearing pin 1 and presses to countershaft and overlap in the inner groove on 7 endoporus tops, expanding ring 3 is in the inner groove of the outer groove of expansion axle sleeve 2 and countershaft cover 7, the part of expanding ring 3 is shelved on the outer groove of expansion axle sleeve 2, another part is hanging the inner groove of countershaft cover 7, has realized expansion axle sleeve 2 and countershaft cover 7 suspension between the two.Main shaft 9 continues to extend upward, and connects other parts.
During use, power passes to main shaft 9 by transmission device, thereafter, on the one hand, main shaft 9 by main shaft key 10 with transmission of power to the axle sleeve 2 that expands, the expansion axle sleeve 2 crosswise groove that overlaps 7 upper-end surfaces of crosswise projection and the countershaft by its edge, upper-end surface again passes to countershaft cover 7, countershaft cover 7 transmits the workpiece axle sleeve 4 that is loaded on its underpart by workpiece shaft sleeve key 6 again, pass to workpiece by workpiece axle sleeve 4, thereby be implemented in the rotation that same vertical shaft down transmits same direction; On the other hand, continue upwardly extending main shaft 9, give other parts transmission of power.
Elastic expansion piece ring twin shaft of the present utility model cover hangs the cross coupling arrangement, is applicable to the connection of device interior when the rotation that same vertical shaft down transmits same direction, such as the vertical secondary that washes away mill connect, the secondary connection of wire stripping machine etc.
