Description
One, technical field
The utility model relates to a kind of deciliter mechanism of high-pressure vacuum breaker, and especially a kind of adaptation is used for deciliter mechanism of the high-pressure vacuum breaker of large-scale transformer station.
Two, background technology
High-pressure vacuum breaker is as the ensuring equipment in the high-pressure delivery circuit, very important effect is played in the fail safe of high-pressure delivery circuit, especially in large-scale networking circuit is carried, therefore high-pressure vacuum breaker is a very important equipment, and in existing high-pressure vacuum breaker, owing to used camshaft to connect with support by copper sheathing, in use, the lubricating grease in the copper sheathing holds dried very much
And do not have lubrication, make the gap of camshaft and copper sheathing increasing, camshaft is made in rotation produce the phenomenon of rocking, thereby influence the contact performance between the contact point of coupling or uncoupling means of high-pressure vacuum breaker, the friction owing to camshaft and copper sheathing simultaneously produces copper powders may, also influences the contact performance between them when copper powders may concentrates on the contact point of coupling or uncoupling means.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of deciliter mechanism of high-pressure vacuum breaker, makes the rotation of camshaft more flexible, and the coupling or uncoupling means operation is more steady.
For achieving the above object, the technical scheme that the utility model is taked is to include, and includes support, camshaft, bearing and positioning sleeve; Support is set to three-dimensional box, bearing is set to self-lubricating type, the inner ring tight fit that the lateral surface at the two ends of camshaft is set to bearing connects, the outer ring of bearing is set to be fixedly connected with support, the middle part of camshaft is provided with the cam that is fixedly connected with it, one end of camshaft is set to connect with the output shaft of motor and the other end is provided with and pulls out plate and ratchet device, is provided with positioning sleeve pulling out between plate and ratchet device and the support of camshaft.
Motor start-up drives camshaft and rotates, camshaft drives cam and makes the coupling or uncoupling means work of high-pressure vacuum breaker, and the rotational angle that pulls out plate and ratchet device positioning cam axle is arranged by the rotation of bearing, by the positioning sleeve location, prevented vertically moving of camshaft; Owing to designed bearing, do not re-use lubricating grease, therefore make the rotation of camshaft more flexible, the coupling or uncoupling means operation is more steady.
The utility model has designed, and bearing is set to the sintered metal powder bearing of wear-resistant self-lubricating formula.Reduced when rotating and powder occurred, thereby powder is accumulated on the contact point in the high-pressure vacuum breaker, influenced the performance of high-pressure vacuum breaker.
The utility model has designed, and also includes bearing pedestal and regulating sleeve; The lateral surface at the two ends of camshaft is provided with the regulating sleeve with its socket, and the inner ring tight fit that regulating sleeve is set to bearing connects, and bearing is arranged in the bearing pedestal and the outer ring of bearing is set to be fixedly connected with bearing pedestal, and bearing pedestal is set to be fixedly connected with support.Prolonged the useful life of bearing and camshaft.
Four, description of drawings
Accompanying drawing is the utility model schematic diagram.
Five, embodiment
Accompanying drawing is an embodiment of the present utility model, specifies present embodiment in conjunction with the accompanying drawings, includes support 13, camshaft 1, bearing pedestal 2, bearing 3, regulating sleeve 4 and positioning sleeve 9; Support 13 is set to three-dimensional box, the lateral surface at the two ends of camshaft 1 is provided with the regulating sleeve 4 with its socket, the inner ring tight fit that regulating sleeve 4 is set to bearing 3 connects, bearing 3 is arranged in the bearing pedestal 2 and the outer ring of bearing 3 is set to be fixedly connected with bearing pedestal 2, bearing pedestal 2 is set to be fixedly connected with support 13, the middle part of camshaft 1 is provided with the cam that is fixedly connected with it, one end of camshaft 1 is set to connect with the output shaft of motor and the other end is provided with and pulls out plate and ratchet device, is provided with positioning sleeve 9 pulling out between plate and ratchet device and the support 13 of camshaft 1.
In the present embodiment, bearing 3 is set to the self-lubricating formula.
In another embodiment of the present utility model, bearing 3 is set to sintered metal powder bearing.
Motor start-up drives camshaft 1 and rotates, camshaft 1 drives cam and makes the coupling or uncoupling means work of high-pressure vacuum breaker, and the rotational angle that pulls out plate and ratchet device positioning cam axle 1 is arranged by the rotation of bearing 3, by positioning sleeve 9 location, prevented vertically moving of camshaft 1.
When using this enforcement, owing to also include bearing pedestal 2 and regulating sleeve 4; Reduce the wearing and tearing of bearing 3 and camshaft 1, prolonged the useful life of bearing 3 and camshaft 1.
Owing to designed bearing 3, made the characteristics of the utlity model has down:
1,, make the performance of coupling or uncoupling means of high-pressure vacuum breaker better because bearing 3 exercise performances are better than copper sheathing.
2, because the specifications and models of bearing 3 are many, the self-lubricating formula is arranged particularly, do not re-use lubricating grease, make high-pressure vacuum breaker can be in rugged environment operate as normal, can select the bearing 3 of different size model according to the field of employment simultaneously, expand the model of high-pressure vacuum breaker.
