Abstract
The invention belongs to the field of machine parts, and relates to an aligning sliding bearing for an efficient air valve of a subway. The aligning sliding bearing comprises a bearing block body (1),a sliding bearing (2), a bolt hole (3), a demounting hole (4) and an oil hole (5), wherein the bearing block body is fixed with an air valve framework by bolts; the sliding bearing is connected witha blade shaft; the demounting hole is arranged in a square shape along the radial direction of an inner hole of a bearing block; and a position which is in the radial direction of the inner hole of the bearing block and is vertical to the length direction of the bearing block is provided with the oil hole. The spherical contact surface of the sliding bearing is matched with the spherical contact surface on the bearing block, so a sliding ball is difficult to slide off in the bearing block and runs more stably, and the spherical surface assembling mode can automatically adjust the concentricityof two ends of a fan blade shaft so as to effectively solve the problem of unstable running caused by the two non-concentric ends of the fan blade shaft because the fan blade shaft is too long when the air valve is in operation. The design of the oil hole of the sliding bearing block can ensure the spherical surface lubricating condition, reduce the friction, and improve the transmission efficiency and the service life of a material.
Description
Technical field
The invention belongs to the mechanical parts field, relate to a kind of be used for efficient air valve of subway can aligning the high-strength high-performance sliding bearing.
Background technique
The bearing of efficient air valve of subway in the market, adopt simple metallic sheath mostly, assemble the back owing to do not have the aligning function with blade shaft on the one hand, can not eliminate the caused force unbalance that is subjected to of blade installation process decentraction resembles, make the fluctuation of service of fan blade, because lubricating condition is bad or the selection of metallic sheath material is improper, cause bearing short working life on the other hand, have influence on the normal use of air-valve.
Summary of the invention
The present invention seeks to be problems such as the blade shaft two ends decentraction that solves efficient air valve of subway, bearing working life is not high.
A kind of aligning slide bearing that is used for efficient air valve of subway, its feature comprises bearing seat, sliding bearing, bolt hole, removal hole, oil hole.Use bolt between bearing seat and the air-valve framework, sliding bearing connects with sharf, at the radially square removal hole that is provided with of inner hole of bearing seat, radially and with the perpendicular position of bearing support length direction oil hole is set at inner hole of bearing seat.
Sliding bearing connects with sharf, and the stator blade axle is finished the spinning movement of sharf on the other hand on the one hand.
Use bolt between bolt hole and the air-valve framework, the easier maintenance of easy accessibility;
At the radially square removal hole that is provided with of inner hole of bearing seat, cylindrical is that the sliding ball of sphere is installed into inner hole of bearing seat by this position, rotates arbitrarily angled back then and just can guarantee not come off when normal the use;
Radially and with oil hole that the perpendicular position of bearing support length direction is provided with can guarantee online oiling in the normal process of using at inner hole of bearing seat,, reduce friction, improve the working life of material for the work of sliding bearing provides good lubricating condition;
The sliding ball of sliding bearing is made up of two parts of center hole and sphere surface of contact: link by center hole and sharf, match with sphere surface of contact on the bearing support by sliding bearing sphere surface of contact.Sliding ball is difficult for landing and more moves more stable in bearing support like this, and the sphere fit can be regulated the concentricity at blade shaft two ends automatically, has effectively solved the situations such as fluctuation of service that cause because of the long blade shaft two ends decentraction of bringing of blade shaft of air-valve emerged in operation.
Adopt the aligning slide bearing of this design on efficient air valve of subway, plain bearing housing is by using bolt between bolt hole and the air-valve framework; The design of plain bearing housing oil hole can guarantee the sphere lubricating condition, reduces friction, improves transmission efficiency, the working life of improving material on the other hand on the one hand.Sliding ball and plain bearing housing surface of contact adopt the sphere design, make this bearing have the self-aligning function, can eliminate the axial dipole field that may occur in the blade installation process; The sliding ball center hole connects with sharf, and the stator blade axle is finished the spinning movement of sharf on the other hand on the one hand; Sliding ball can adopt refractories such as stainless steel or copper material, the working life that can improve this device.
