Abstract
The present invention relates to a kind of idle gear pad, cushion block is a ring entirety, and its face back to idle gear is plane, and the face contacted with idle gear is for arranging reeded plane, and the center line of described groove is curve or straight line; When the center line of groove is straight line, the center line of described groove is greater than with the angle of the radial line of the cushion block annulus heart but is not equal to zero degree.
Description
Technical field
The present invention refers to for idle pulley installation in gear chamber before and after motor and protection train field, refers to a kind of gear cushion block limiting idle gear axial motion especially.
Background technique
The major function of gear cushion block is the axial motion of limiting gear, ensures gear-driven steady, reliable.Existing idle gear pad is cirque structure, middle for bolt mounting holes thrust surface be plane structure.
The working principle of idle gear pad is pressed on idle gear shaft by fixing bolt, and idle gear and idle gear pad are designed with certain axial clearance, and existing axial clearance is generally between 0.1-0.2mm, and axial clearance is used for ensureing that idle gear can normal rotation.When the existence of idle gear rotation process moves axially, idle gear pad can stop moving axially of idle gear, ensures that idle gear rotates steady, reliable.
Idle gear in rotation process, and has between idle gear pad to rub and produces, and in order to prevent the wearing and tearing of idle gear and idle gear pad, improves slickness to reduce to rub on the surface that idle gear contacts with idle gear pad by lubricant oil.
Idle gear pad in existing technology is plane with the surface that idle gear contacts, and such plane structure makes lubricant oil be not easy to enter between two surfaces, and lubrication effect is bad.In order to improve the lubrication effect between idle gear and idle gear pad, Chinese Patent Application No. is that 201120430439.x patent proposes improvement project to idle gear pad, increases lubrication effect by being provided with uniform radial fluting on two surfaces of idle gear pad.But this technological scheme has obvious defect: be on the one hand, idle gear pad in the course of the work, it only has a face to contact with idle gear, and what another face contacted is fixing bolt, is provided with the cost of production of slotting without any acting on and add cushion block on the surface contacted with fixing bolt.Another aspect is when adopting radial fluting in idle gear pad, the direction of relative movement of idle gear and idle gear pad is be in plumbness with fluting substantially, and the collar extension of fluting can be closed by lubricant oil that this state drives when causing idle gear to move in the form of a film, make to enter into the lubricant oil limited amount with idle gear surface of contact, although make moderate progress with the lubrication effect of the idle gear pad of not slotting, improve DeGrain.
Summary of the invention
The object of this invention is to provide a kind of idle gear pad improvement opportunity scheme, by improvement opportunity scheme, raising the efficiency under the prerequisite reducing cost, improve the lubrication effect of idle gear and idle gear pad surface of contact.
The present invention is achieved by the following technical solutions:
A kind of idle gear pad, cushion block is a ring entirety, and its face back to idle gear is plane, and the face contacted with idle gear is for arranging reeded plane, and the center line of described groove is curve or straight line; When the center line of groove is straight line, the center line of described groove is greater than with the angle of the radial line of the cushion block annulus heart but is not equal to zero degree.
Described groove is distributed in the toroid surface of cushion block.
Described groove is that both ends open is in the through groove of cushion block exterior edge face.
The quantity of described groove is at least two.
The cross section of described groove is in the isosceles trapezoidal structure lacking upper bottom surface.
The angle of two waist limit elongation lines of described isosceles trapezoidal structure is 30 degree to 90 degree.
Described groove two inclined-plane is provided with circular arc lead angle with the plane symphyses of idle gear pad.
The present invention's beneficial effect is compared with the existing technology:
1, the technical program is passed through, groove has opening to have certain angle with the sense of rotation of idle gear all the time, such groove can not produce oil film closed phenomenon because of the rotation of idle gear in the end face opening of idle gear pad, lubricant oil can enter into the surface that idle gear contacts with idle gear pad easily, improves lubrication effect.
2, by the technical program, only fluted in a surface Machining of idle gear pad, decrease manufacturing procedure, reduce cost of production.
