Abstract
The utility model discloses a headstock gear shift fork, which comprises a bearing, a pin and a shift fork, wherein the shift fork is provided with an upward rectangular opening; the opening is relatively provided with a circular hole; the bearing is arranged in the opening; and the pin passes through the relatively provided circular hole on the opening and the central hole on the bearing. The headstock gear shift fork has simple structure, and is convenient to operate and durable.
Description
Technical field
The utility model relates to a kind of headstock gear shift fork.
Background technique
At present, the headstock gear shift fork comprises slide block, pin and fork, in the actual using process, uprise slow-speed of revolution shift fork in use slide block cause slide block to damage with rubbing between the chute, increase and repeat to change the slide block number of times, sliding-frictional resistance is big, wearing and tearing are big.
The model utility content
Technical problem to be solved in the utility model provide a kind of can reduce and chute between the headstock gear shift fork of surface friction drag.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of headstock gear shift fork, comprise bearing, pin and fork, described fork is provided with the rectangular aperture that opening makes progress, be relatively set with circular hole on the opening, bearing is arranged in the opening, and pin passes the circular hole that is oppositely arranged on the opening and the center hole on the bearing.Use to roll replace slide, it is little that surface friction drag is compared in rolling friction and sliding friction, and it is little wear and tear, and with the bearing replacement slide block of a rolling, the bearing top circle of rolling turns round simultaneously with chute.This Bearing Installation is used to stir the engagement between shifting slide gear and different gears, thereby changes velocity ratio on the level V transmission shaft, reaches the effect of speed change.Have an annular groove to cooperate with bearing on the shifting slide gear cylindrical, endoporus is a spline structure, and when stirring operating stem, bearing touches shifting slide gear and moves at splined shaft, observes the scale indication, toggles it to the position that needs and gets final product.
As preferably, the center line of described bearing and pin is vertical.
As preferably, described bearing can be in the pin axial rotation.
A kind of headstock gear shift fork of the utility model, it is simple in structure, and is easy to operate.Bearing contacts for a long time with annular groove on the gear, and wearing and tearing reduce greatly, have prolonged working life, and slide block damages to be changed number of times and also reduce thereupon.Change slide block structure in the past into rolling structure, replace slide block, prolonged bad usefulness by the bearing that rolls.Under the situation that guarantees lathe function, can reduce wear convenient operating maintenance again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the plan view of a kind of headstock gear shift fork of the utility model.
Fig. 2 is the left view of a kind of headstock gear shift fork of the utility model.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
As depicted in figs. 1 and 2, a kind of headstock gear shift fork of the utility model, comprise bearing 1, pin 2 and fork 3, described fork 3 is provided with the rectangular aperture that opening makes progress, be relatively set with circular hole on the opening, bearing 1 is arranged in the opening, and pin 2 passes the circular hole that is oppositely arranged on the opening and the center hole on the bearing 1.
As depicted in figs. 1 and 2, bearing 1 is vertical with the center line of pin 2 described in a kind of headstock gear shift fork of the utility model.
As depicted in figs. 1 and 2, bearing 1 can be in pin 2 axial rotation described in a kind of headstock gear shift fork of the utility model.
A kind of headstock gear shift fork of the utility model, it use to roll replace slides, and it is little that surface friction drag is compared in rolling friction and sliding friction, and it is little wear and tear, and with the bearing replacement slide block of a rolling, the bearing top circle of rolling turns round simultaneously with chute.This Bearing Installation is used to stir the engagement between shifting slide gear and different gears, thereby changes velocity ratio on the level V transmission shaft, reaches the effect of speed change.Have an annular groove to cooperate with bearing on the shifting slide gear cylindrical, endoporus is a spline structure, and when stirring operating stem, bearing touches shifting slide gear and moves at splined shaft, observes the scale indication, toggles it to the position that needs and gets final product.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
