Abstract
A speed reducer for outputting a rolling pin block comprises the rolling pin block, an input shaft, a planetary gear, an internal gear, an output shaft, a shell and the like, wherein the rolling pin block is composed of an annular block body (5) with two parallel end surfaces, a pin shaft (6) in an interference fit in a hole of the annular block body, and a rolling body (7) sleeved on the pin shaft (6). The utility model discloses K-H-V type planetary drive formula reduction gear than traditional output mechanism simple structure, processing are convenient, when replacing slider formula output mechanism's K-H-V type reduction gear, and transmission power increases to more than 10KW from 2.2KW, and transmission efficiency improves to can continuous operation.
Description
The utility model is a kind of K-H-V type epicyclic transmission type retarder with rolling pin block output mechanism.
With involute planetary gear gear transmission and cycloid pinwheel planetary gear transmission system is the K-H-V type speed reducer of typical case's representative, and output mechanism is the critical component to its performance parameter tool significant impact.Up to now, 5 kinds of output mechanisms are arranged altogether: 1. pin-and-hole formula; 2. zero tooth differential; 3. double crank type; 4. unsteady disc type; 5. slide block type.Preceding four kinds of output mechanisms are than the transmission efficiency height of 5. planting the slide block type output mechanism, but complex structure relatively, machining accuracy and assembly condition require high, and cost is more expensive.And in fact the slide block type output mechanism of 5. planting is equivalent to a crosshead shoe shaft coupling, structure, processing are very much simple, but surface of contact is sliding friction, power loss is bigger, (referring to " mechanical design handbook ", Xu Hao edits, and publish in September, 1991 to be only applicable to discontinuity running or lower-powered occasion, China Machine Press, the 24th piece of P78 page or leaf of the 3rd volume).
The purpose of this utility model is the deficiency at above-mentioned all kinds of output mechanisms, provides a kind of both simple in structure, easily manufactured, keeps a kind of KHV type speed reducer with rolling pin block output mechanism of higher transmission efficiency again.
For achieving the above object, retarder of the present utility model comprises input shaft (1), eccentric shaft equilibrium block disjunctor (2), planetary external gear (3), internal gear housing (4), frame (8), output shaft (9), it is characterized in that annular block (5) that both ends of the surface parallel, with block (5) in the pin-and-hole interference fit bearing pin (6), be enclosed within the roller bolt block assembly that the rolling element (7) on the bearing pin (6) is formed.The bearing pin center that is symmetrically distributed on each end face of this assembly must be positioned on the straight line, preferably on diameter line; This line of centres is projected as strict vertical reticle on the positive and negative end face.
Accompanying drawing is a relevant structure of the present utility model.

E---Gear Planet Transmission throw of eccentric.
Below in conjunction with description of drawings working principle of the present utility model and an embodiment.
Figure 1 shows that a kind of little tooth difference speed reducer of single eccentric planet wheel counterweight formula of charged motivation, the utility model is such transmission: the output shaft of motor (10) is input shaft of the present utility model (1), because the effect of eccentric shaft (2) forces planetary external gear (3) not only to revolve round the sun but also the planetary motion of rotation around housing internal gear (4), because of planetary external gear and the internal gear number of teeth differ seldom, so the motion that external gear (3) is done around the axis of eccentric shaft (2) is reverse low speed spinning motion, this move through be inlaid in the relevant end face respective slot of external gear (3) with output shaft (9) by block (5), bearing pin (6), the rolling pin block that rolling element (7) is assembled into passes from output shaft, to realize the retarded motion opposite with the input shaft direction.Above principle is same as the working principle of the known K-H-V type speed reducer of people slide block type output.And in the structure of the two eccentric symmetric row star-wheel in prior art (no balance reprovision piece), also this rolling pin block transmitting movement of available same size between two planet wheels.
Rolling pin block of the present utility model as shown in Figure 2; The roller bolt block structure of a plurality of rolling elements of tool as shown in Figure 4.Block (5) is made with modified heat treated No. 45 steel or 40cr steel, and Vehicle Processing is not more than the ring bodies of 0.015mm for the both ends of the surface parallelism error, bores, cuts with scissors out pin-and-hole then, and on surface grinding machine with grinding two end surfaces to given size; The available commercially available standard piece roller of bearing pin (6), materials such as the alloyed steel of also available Gcr15 or low carbon high-strength degree good toughness such as 20GrMn-M0VBA are made, and rolling element (7) is used similar materials processing always, but heat treatment hardness should be low than bearing pin (6).Rolling element also make by engineering plastics such as available nylon or phosphor bronze when the small-power transmission.The rolling element profile mostly is hollow circular cylinder, also can be made into the outer surface of cydariform or taper in case of necessity; Simultaneously, also should make corresponding groove shape on the external gear that matches with it and the position of output shaft.Substitute at the also available needle bearing of the higher occasion rolling element of rotating speed, rolling bearing etc.
The available plunging of bearing pin (6) is pressed in the respective pin hole of block (5), and also available hot charge practice is placed on block (5) in the deep fat (150-200 ℃) pin-and-hole is swollen, and bearing pin is put into pin-and-hole, is secure fit after the cooling.
During final assembly rolling element (7) being enclosed within bearing pin (6) upward gets final product.
The utility model is compared with five kinds of output patterns of K-H-V type speed reducer transmission, has advantage significantly simple in structure, easy to process, with low cost than pin-and-hole formula, zero tooth differential and double crank type; Compare with unsteady disc type, engineering circles is for reducing the transmission noise at present, lower processing charges, with planetary external gear just being gradually adopted the material that strengthens these class tool flexibilities of engineering plastics such as nylon, if it is often easily loosening and cause accident to be fixedly mounted with bearing pin in these materials, but the utility model only needs in these material compactings or injects groove at once, makes things convenient for safely; Therefore be beneficial to promoting the use of and not having a machining of New Type Material gear; Compare then with the 5th kind of cross slider type and to change rolling friction into by sliding friction, transmission efficiency is improved, temperature rise reduces. The K-H-V type speed reducer of cross slider type output is original multiplex in the following occasion of 2.2KW, use the utility model instead after transmitted power surpass 10KW, prodigiosin moves continuously. When substituting crosshead shoe, need not change the rolling pin block of this utility model other any parts in the decelerator.
